Before we start, I'd like to point out that this conference call may contain projections or other forward-looking statements regarding future events or the future performance of the company. These statements are only predictions, and Allot cannot guarantee that they will in effect occur. Allot does not assume any obligation to update that information. Actual events or results may differ materially from those projected, including as a result of impact due to the COVID-19 pandemic, changing market trends, reduced demands, and the competitive nature of the security system industry, as well as other risks identified in documents filed by a company with its Securities and Exchange Commission. With that, I would now like to hand over the call to Erez. Erez, go ahead, please. Thank you, Ehud. I'd like to welcome all of you to our conference call, and thank you for joining us today. Our fourth quarter was another quarter of solid growth. Revenues grew 28% year-over-year for the fourth quarter and reached $39.1 million. Revenues for the full year 2020 grew 23% compared to 2019 and reached $135.9 million. Our revenue growth in 2020 accelerated compared to our revenue growth rate in previous years. In the fourth quarter, we also achieved non-GAAP operating profit of half a million dollars. This is our 12th straight quarter of double-digit revenue growth year-over-year, and I am very pleased with the results we achieved during the fourth quarter. During 2020, we succeeded in signing recurring security revenue deals with an aggregate MAR of $192 million, 37% above our original goal for the year, a goal which we declared prior to the onset of the global pandemic. I am very pleased with these results, and I believe it shows we are on track and successfully executing on our plan. Our business is expanding across our product lines and markets, and we are increasing our market share, especially in the cybersecurity business, as I will describe in more detail. As we see our opportunities grow, we increased our investments to capitalize on the significant number of opportunities that we see. Ziv will provide more details on our financials and forecasts later. The fourth quarter was clearly a very strong finish for a very successful 2020. 2020 was a different year, not in the least as a result of COVID and its impact on business, reduced travel, and significant changes in our mode of operation. I think we can all get a clearer picture if we summarize 2020 as a whole at this point, rather than focus on the fourth quarter. I want to start by describing what we see in our cybersecurity business and how the market is changing favorably for Allot. Allot is rapidly transforming into a cybersecurity company, and this is where we see most of our future growth coming from. Looking at the market, I see what I would call a "perfect storm." Consumers are under attack, and this notion is accelerating during COVID. Phishing, for example, has become more prevalent than ever. In a recent study by Deloitte, we see that nearly half of individuals fall for phishing scams while at home. In Allot study, we found that phishing attacks are more than half of all the cyber threats targeting consumers and SMBs. On the other hand, CSPs or communication service providers, are looking to monetize their networks. They are looking for subscriber services that drive revenues, loyalty, and brand differentiation. To quote a senior VP for wireless products in a major North American operator I recently talked to, "We are hungry for ARPU-generating services, and if what you are showing us is true, this is a real ARPU growth generator." In discussions we have with many CSPs, we see this drive becoming accelerated by their 5G deployments. The design of 5G networks for higher bandwidth and multiple internet connection points makes them more open to threats. In addition, the investment required is very large. All these make 5G networks, in my view, a catalyst for cybersecurity solutions. End users, consumers, and SMBs are looking for a simple zero-touch cybersecurity service. They prefer a simple security service and not have to do anything technical, like downloading an app to each device and configuring it. A network-based cybersecurity solution is the only way to deliver all of this. A growing number of CSPs want to launch a cybersecurity service for their customers, for their consumer, and SMB customers. Previously, even one year ago, many CSPs thought that reselling a security app was sufficient for their customers. This, in my view, has changed significantly in 2020, and now we see that most CSPs we talk to understand that they need to provide a network-based cybersecurity service. North American operators have, based on our interaction with them, quote, "turned the corner," end quote, on cybersecurity services for consumers. We are closely interacting with multiple North American operators that are now seriously looking into launching network-based security services for the mass market. This was not the case a year ago. While we cannot be assured, of course, of any success, the requirement from the operators is now clearly there. Operators worldwide can typically charge for network-based security services anywhere from 5%-7% of the consumer's ARPU, and around 15% of the SMB's ARPU. The preferred business model that most, but not all, operators worldwide are accepting of is a monthly fee. Whether a revenue share or monthly per-subscriber fee, 30%-50% of the perceived end-user value is considered a reasonable range for an all-inclusive security service package. As a result of all the above, our deal pipeline is very robust, and it has grown significantly. The total MAR of all the opportunities we are actively engaged with is higher than in any previous time. I would now like to look at Allot and how we are uniquely positioned to turn these exciting market developments into accelerated growth. I will start with our platform and product. The Allot Secure 360 platform is a clear differentiator. To remind us all, Allot offers a unified management, threat database, policies, user experience, reporting, and user control, protecting families across all devices. This can be done regardless if the connectivity is mobile, fixed, or even off network. Allot provides enforcement points for the security in the mobile network, 4G or 5G, in the home router, in the business router, and even security apps on the devices for off-network protection. These holistic capabilities are unique in the industry and are very appealing to many operators. I believe we have today the widest range of security enforcement points available from any competitor. I am not familiar with other technology companies that can provide such a unified experience across access means, devices, and threats. Recently, we announced an agreement to develop together with PowerDNS a DNS security enforcement product, DNS Secure, that will be an integral part of the Allot Secure platform. I explained in the past that DNS security is inherently inferior to NetworkSecure and cannot provide the same level of protection. This is true for our DNS Secure solution as well. However, DNS-based security is a much lighter touch on the network and requires less hardware. We believe our DNS security solution will expand our addressable market to include fixed networks, especially in low ARPU countries where the perceived dollar value of a security solution is lower. When we look at our recurring security revenue growth path, we see our revenues growing in three dimensions. One, signing up and launching cybersecurity services with additional CSPs. Two, in a CSP that launched the service, having more end users signed up for this security service. Three, CSPs expanding the security offering to the market from an initial market segment, such as mobile, to additional segments, such as the home or off-net protection or the SMB market. I believe this threefold growth opportunity is what can make our recurring security revenues grow very rapidly. I would like now to turn our attention to the deals we signed in 2020 and the results in the services the operators launched. In 2020, we signed multiple new security deals with operators who intend to launch the security service in 2021. Most of these deals, primarily due to COVID-related delays, were signed in the fourth quarter of 2020. These deals were with CSPs in EMEA, APAC, and Latin America. They include NetworkSecure, HomeSecure, and EndpointSecure. In 2020, several operators who started with one product, typically NetworkSecure for mobile, decided to expand the service to include EndpointSecure for off-net protection and HomeSecure for fixed network protection. Another interesting area we see is the SMB segment. A growing number of operators see SMB as a lucrative segment. Several of the deals we signed in 2020 are either focused exclusively on SMB or have specific plans to service this specific segment. During 2020, several operators in Europe and Asia Pacific, who previously signed deals with us, launched the services to their customers. The take-up rates we see in these operations are very encouraging. I will note that the actual rates depend significantly on the go-to-market strategy the operator takes. The more aggressive the go to market, the higher the rate of customers signing up. We see that selling in shops is a very effective means of adding new customers. When offered as a paid value-added service, one operator is seeing that over 80% of new customers who join their network in shops choose to add the security service option. Moreover, a year after they purchased the service, two out of three customers keep it. These are very high conversion and longevity numbers. Another operator who launched the service as a paid-on service offered to customer with every operator interaction, managed to get 10% penetration in less than six months. While this is a truly outstanding penetration rate that we should not expect to replicate in many operators, it shows the appeal and potential of the service to consumers. On the other hand, operators who launched the service with less aggressive go-to-market plans, such as digital means only, achieved significantly lower take-up rates. Our marketing team is heavily engaged with these operators' marketing teams to show them how they can improve the results. On average, the penetration rates we are seeing in the services launched are very encouraging. We also continue to see take-up rates from SMB typically higher than the average rate for consumers. One SMB service reached more than 40% penetration in 18 months. I will note, though, that there are much fewer SMBs than consumers, so the potential value of SMB deals is typically lower than that for consumers. As I mentioned in previous calls, Allot not only enables the CSPs to protect consumers and SMBs, but we also protect the CSP network itself from attacks. In the 4G world, we protect the network with our DDoS Secure product. As 5G networks are rolling out, they are more susceptible to volumetric DDoS attacks. As a result, we are seeing significant traction for our NetProtect product. As I discussed in our previous call, Allot has a unique position to play in securing the user plane in 5G networks. Our combination of being able to analyze in real time the full traffic flow, ability to mitigate DDoS attacks inline very quickly, and protect the network from rogue IoT devices, puts us in a unique position to help operators secure their 5G network. Allot comes to the 5G world with a very strong telco-grade technology, products that scale easily to the 5G bandwidth requirements, and full multi-tenancy support to enable differentiated services. These abilities are key differentiators for us in the future 5G deployments. While we cannot ensure we will win, I hope we will be able to close one of these deals in the coming months. To summarize, I believe the market for cybersecurity services by CSPs to consumers and SMBs is taking off. Our pipeline is stronger than ever. I believe Allot is uniquely and very well positioned to take advantage of this and grow significantly. New deals with CSPs still take time, usually between 12 and 18 months, and with COVID, some even take 24 months. Once signed, it takes nine months to launch the service and start gradually building a revenue base. COVID-19 may cause even several months further delays in launch of services after the deal is signed. Factoring in all this, we expect recurring security revenues in 2021 to be between $6 and $8 million. Looking farther ahead, we expect recurring revenues from security deals in 2022 to be $25 million, and to keep accelerated growth year after year after that. We also expect to sign in 2021 new recurring security revenue deals totaling at least $180 million of MAR. Before turning to the DPI for Allot Smart, I would like to say a few words on the changes we went through in 2020 and their impact on the company. As with many companies, COVID-19 dramatically restricted our international travel and ability to be physically present at customer sites and meet customers face-to-face. As a result, we made a series of changes to adapt our mode of operation. Our sales team transformed the way we initiate interaction and generate leads. From mostly physical meetings, conferences, customer gatherings, et cetera, we partially adopted targeted digital means to approach the relevant decision-makers and potential customers. This has been successful for us and opened up quite a few interesting opportunities for recurring revenue security deals, both for consumers and for SMBs. Implementation was harder this year, as we could not send engineers to install systems on-site. Work was done mostly by remote connection. In one case, we had to install a complete network in a country we had never worked in before and were not even familiar with local integrators. Everything was built and pre-installed in racks in Israel and shipped to the country whole. We identified a local integrator, trained them remotely with video clips on how to install and turn on the service, and succeeded to pass acceptance without stepping into the country. Internally, we modified our structure this year to fit the changing needs. As we discussed in our previous call, we created two separate product business units, one for Allot Secure and one for Allot Smart. In the short months that passed since the change, I can see the value that focusing on each product line is already bringing to product development and to new deals. In our global support services, we moved headcount and resources from expensive region to lower cost geographies, mostly to India and Colombia. This transition and transfer of knowledge was not easy. We succeeded to complete the task this year while reducing the number of open trouble tickets, despite the growth in revenues and the growth in our installed base. In addition, we strengthened significantly the number of salespeople focusing solely on security deals worldwide. I think perhaps the biggest change for us resulted from a political change, the Abraham Accords and peace treaties that Israel signed with Arab countries. These agreements opened up the Gulf market to Allot, especially in the UAE and Bahrain. My first and only international trip after COVID started was actually to Dubai in December. Little could I have guessed that a year ago. I am very pleased to say the business atmosphere in the Gulf region is very positive towards working with Allot, and we are actively engaged in several opportunities in both DPI and security. I would like to turn now to discuss our visibility and control business addressed by our Allot Smart product line. This business grew well for us in 2020. The main use cases we see today are in congestion management, quality of user experience, especially for video, policy and charging control, and digital enforcement. We won several deals this year where we replaced a direct competitor's product that was installed, one of them in a tier 1 in Europe. We are discussing similar opportunities with other CSPs using our competitor's product. In addition, we are involved in several RFPs with operators who do not have such systems today on their networks. While we cannot be assured of success, we are optimistic regarding our chances in some of these opportunities. Our enterprise business grew and had a record year. The deal we signed in the beginning of 2020 with Broadcom to position Allot as the replacement for PacketShaper product, which is end of life, is starting to show results. We signed new distributors for our enterprise products in several countries, including the U.S., and we expect continued growth of the enterprise business in 2021. To summarize, I believe demand for the Allot Smart product line, including congestion management, traffic management, analytics, digital enforcement, and enterprise use cases, will remain healthy with growth for Allot in the years to come. I would now like to summarize the overall picture and key messages. We are proceeding according to our plan and continuing to grow the business. In the Allot Smart product line, we see a strong pipeline. Multiple use cases, such as congestion management, digital enforcement, and the enterprise business, are growing. Overall, we see a solid demand for Allot Smart. The security area is where we see our long-term growth. We are very encouraged by the pipeline growth we see and by the consumer and SMB take-up rate as they sign up for the service. We signed significant deals for our various products and succeeded in exceeding our MAR target for 2020. While these deals always take time to close, COVID-19 pushed the closure of several deals a bit more. It is also postponing services commercial launch in some of the deals that were already signed. Overall, the pipeline is robust and growing. Across our product line, we see positive signs from the market. To take advantage of these growth opportunities, we decided to continue our significant investment in developing the full breadth of Allot Secure products and our solutions for 5G, as well as in our sales and support teams. Ziv will discuss the numbers in more details later. Looking at our backlog, the market demand as we see it now, and the pipeline of deals that we are working on, our revenue guidance for 2021 is between $145 million-$150 million, including between $6 million-$8 million of recurring security revenues. We further expect to sign additional recurring security revenue deals with an MAR exceeding $180 million. Now, I would like to hand the call over to Ziv Leitman, our CFO. Ziv, please go ahead. Thank you, Erez. Before I begin reviewing the financial results for the quarter and for the year, I would like to inform everybody on this call, unless otherwise noted, I will refer entirely to the non-GAAP financial measurements when discussing operational results, which is what we use internally to judge the performance of our business. Non-GAAP financial measures differ in certain respects from the generally accepted accounting principles and exclude share-based compensation expenses, revenue adjustments due to acquisition, restructuring expenses related to M&A activities, amortization of certain intangible assets, exchange rate differences, changes in tax-related items, and changes in deferred taxes. Now, regarding the financial results. We are pleased with the revenues for the fourth quarter of 2020, which were $39.1 million, growing by 28% compared with those of the fourth quarter of 2019. Revenues for the full year of 2020 were $135.9 million, growing 23% compared to 2019. In line with our expectation, despite a much more difficult year than anyone could have anticipated at this time last year. Our year-end backlog was $110 million. You may remember we said backlog would be below that of year-end 2019 because of the outstanding orders that were received in the second half of 2019. For the year 2019 and 2020 together, the book-to-bill ratio was 1.17. I would like to give you some more color regarding the revenue breakdown and the certification. The geographic breakdown for the fourth quarter of 2020 was as follows: Americas was $1.9 million, or 5% of revenues. EMEA was $29.6 million, or 76% of revenues. Asia Pac was $7.6 million, or 19% of revenues. For the full year of 2020, geographic breakdown was as follows: Americas with $8.1 million, or 6% of revenues. EMEA with $104.3 million, or 77% of revenues, and Asia Pac with $23.5 million, or 7% of revenues. Regarding the breakdown between products and services, for the fourth quarter, it was as follows. Product revenues were $28.8 million compared to $18.2 million last year. Professional services revenues were $2.5 million, compared to $3.3 million last year. Support and maintenance revenues were $7.8 million, compared to $9.1 million last year. For the full year of 2020, the breakdown was as follows. Product revenues accounted for $94.4 million, compared to $67.4 million last year. Professional services revenues were $11.4 million, compared to $8.5 million last year. Support and maintenance revenues were $30.1 million, compared to $34.2 million last year. Portion of communication service providers revenues out of total revenues were 82% in the fourth quarter, compared to 76% in Q4 last year. 84% for the full year of 2020, compared to 81% last year. It is worthwhile mentioning that the enterprise revenue in dollar terms slightly increased versus 2019, to a level of $21 million, and we do expect a double-digit increase in 2021 enterprise revenue, mainly because of the healthy pipeline, which was generated due to our deal with Broadcom. Security revenues in 2020 were $22.8 million or 17% of total revenues. This is compared to $26.3 million or 24% of total revenues in 2019. I would like to stress that we are in a process of shifting from security CapEx deals to a revenue share model of recurring revenues. By nature, the outcome of such transition, typically, a short-term reduction in the security revenue. While the long-term ongoing revenue potential from the Security as a Service deals will be significant, the new SECaaS deals will take time to ramp, and they are typically nine to 12 months before signing with the customer and the commercial launch. After the launch, revenue should start to ramp up slowly over many months as the subscriber sign on to the new service and the penetration gradually increases. Furthermore, the COVID-19 pandemic has increased the time it takes to sign new deals, and the pandemic has somewhat delayed the launch of already signed deals. Please note that the revenue breakdown, whether geographical or by product line or any other, may fluctuate from quarter to quarter depending on the specific revenue and deals we recognize in the specific quarter. Our top 10 end customers made up 71% of our revenues in 2020, compared with 56% in 2019. Looking further down to the income statement, gross margin for the quarter was 70.9% compared to 68.7% in the fourth quarter of last year. Gross margin for 2020 was 71.2% compared to 70.2% in 2019. The variation between the quarter reflect the product mix sold, It is not indicative of any specific trend. Operating expenses for the quarter were $27.3 million, compared to $22.8 million as reported in the fourth quarter of 2019. For 2020, operating expenses were $100.2 million compared to $85.3 million in 2019, which primarily reflects an increase in head count, mainly an increase in R&D expenses in order to capitalize on the opportunities we see in our market. The total worldwide market number of full-time employees as of December 31st, 2020, was 676. This is an increase of 82 full-time employees compared with that of the end of 2019, which stood at 594. Operating income for the quarter was $475,000, compared with an operating loss of $1.8 million in the fourth quarter of 2019. Net income for the quarter was $382,000, or $0.01 earnings per share, versus a loss of $1.7 million or $0.05 loss per share in the fourth quarter of 2019. Net loss for 2020 was $3.6 million or $0.10 per share, versus $7.5 million or $0.22 per share in 2019. For the three months ending December 2020, the number of basic shares was 35.3 million, and the weighted average number of fully diluted shares was 37.6 million. Turning to the balance sheet, our cash reserve comprised of cash equivalent, and investment as of December 31st, 2020, totaled $99.4 million compared to $107.2 million as of September 2020, and $117.6 million as of December 31st, 2019. I note that toward the end of 2019, we received large advanced payment from deals signed in 2019, and the comparative cash decrease between December 31st, 2019, and the year-end 2020, was primarily due to that. We are expecting a negative cash flow in 2021 in the range of $23 million-$25 million, while our operating loss is expected to be between $6 million-$8 million. The reason for the gap between the expected loss and the cash flow is mainly due to the following. First, I know to the highlightThat in 2019 and 2020, we had a typical high advance payment from customers, which led to a low level of year-end accounts receivable of $21 million. We are not expecting to receive such high level of advances in 2021, so the accounts receivables level at the end of the year is expected to be significantly higher than the AR level at the end of 2020. Second, we expect increased revenues in 2021, which will lead to even a higher AR. Third, as part of our accelerated growth of security revenue share deal deployment, we will need to invest a few million dollars in CapEx. We expect gross margin for 2021 to average around similar level as in previous years, at around 70%. However, it is important to understand that gross margins may fluctuate on a quarterly basis as a result of a deal mix and revenue recognition. As we continue to invest in sales and marketing and R&D to facilitate the growth of the company, we expect 2021 operating expenses to be in the range of $110 million-$111 million. This increase in expenses is expected to be a combination of increase in head count, negative effect of exchange rate to the US dollar, and others. The outcome of the above is expected to generate an operating loss in 2021 of $6 million-$8 million, as I mentioned earlier. I want to highlight that we have actively taken the decision to increase our investment in R&D and sales and marketing. With a balance sheet with a significant amount of cash, we feel that investment to capitalize on the opportunities we see for strong long-term growth is much more important and trump short-term profitability consideration. Our view is that eventual profitability will come via growth, and we do not feel it is necessary right now to anchor to a short-term profit target. In 2020, we signed six deals with an MAR of $192 million, which bring us an accumulated MAR of $280 million. We believe that in 2021, we will sign additional deals with MAR of $180 million. I would like to remind everybody that MAR, which stand for maximum annual revenue potential of concluded transaction, was estimated by Allot upon transaction signature, and constitutes an approximation of the theoretical annual revenue Allot would receive if 100% of the customer subscribers, as estimated by Allot, sign up this service. As I have explained, takes a lot of time from contract date to commercial launch, and then the ramp-up of penetration. Therefore, in 2020, we booked Secure revenues of only $1.9 million. Since most of 2020 new Secure deals we signed towards the end of the year, the expected recurring security revenue in 2021 will be in the range of $6 million-$8 million. To sum up my comments, we are very pleased with Allot 2020 achievements and growth, hitting our targets. This is even more impressive when we take into account the COVID-19 headwind throughout 2020. We are expecting to continue our growth and investment in 2021 in order to fortify the company foundation and capitalize on the potential given the expected accelerated growth starting 2022. That conclude my remarks. We would be happy to take your question now. Operator? Thank you ladies and gentlemen at this time. We will begin the question and answer session. If you have a question, please press star one. If you wish to cancel your request, please press star two. If you are using speaker equipment, kindly lift the headset before pressing the numbers. Your questions will be pulled in the order they are received. Please stand by while we poll for your questions.The first question is from Alex Henderson of Needham & Company. Please go ahead. Alex? Sorry, forgot to unmute. Thank you very much. I heard a little crackle on the line when you gave the book-to-bill comment. Could you just restate what you said about book-to-bill for 2020? For 2020, it was around 0.8, but for 2019 and 2020 together, it was 1.17. That's what I said. Okay. I didn't catch it. It was just crackle. Thanks. As I'm looking at the numbers here and the mechanics associated with them, it looks like the growth, in 2021, at the low end of the band, you're looking at essentially 2% kind of growth, excluding the security business. With the comments about double-digit growth in enterprise, it would suggest that you would actually see maybe a little bit of shrinkage in the service provider, more traditional business. Is that mechanically correct? Is that a function of the, obviously, drawdown and backlog that occurred over the course of 2020, which ultimately, is a reflection of COVID and the like? Am I doing the math right there? Yeah. The numbers are okay. As we said in the past few times, we think that the DPI market, including the enterprise, is supposed to grow single digit each year. Since it's not such a huge market, and there might be big deals, there might be fluctuation. One year it might grow more, and another, it might grow less. Hopefully, we'll do more than the lower range of our guidance. Yeah. Look, I'm not saying that it's a bad thing. I just want to make sure I had the calculus correctly. The second question is around the acceleration in investment to drive this security business, which I think is probably the right thing to do. Certainly, the opportunity here is significant, and the MAR that you've already delivered is outstanding. Can you give us some sense of the mechanics around that? Have you already started that investment in the fourth quarter? Are you going to ramp it from there sequentially into the March quarter, or is it going to be spread out over the course of the year? What's the tempo of that acceleration in investment? As we said, the total OpEx for the year will be between $110-$111. This includes everything. It will be spread all over the year. It's not going to be a one-time investment in Q1. Okay, it's fairly evenly distributed in terms of the sequential increase. Is it more in sales and marketing, more in R&D? How do we split between the growth in those two? I would say it's more in R&D, but also in sales and marketing. Okay. It's more in R&D. Now, if you take it evenly, and you take the 110 divided by four, you see that it's similar to the expense level of Q4. I see. Okay. In terms of the ramp of programs that you just signed, obviously very heavily skewed to 4Q. One of the obvious questions is, what kind of programs are the customers putting in place, in terms of marketing? Are they the more aggressive programs? Do they tend to be more conservative coming out of the COVID-19 environment? Can you qualitatively talk a little bit about what you're hearing and seeing from them in terms of their marketing programs against that very large MAR number? We're seeing a mixture. Some are looking at it very aggressively. Some are looking at it less aggressively. This is still in discussions between us and them and for the operators also internally. Until they actually launch, these plans can change. Hopefully, we will help convince them to change for the more aggressive route. I think that from the get-go, there's a mix. Each operator has his own view on what he wants to achieve with this. Those that are more skewed towards let's get revenues and get revenues quickly are taking an aggressive go-to-market. Those that are looking more at overall brand recognition, and that's their beginning, may be a bit more hesitant on how aggressive to go. We're working very tightly with them to show them the advantages, what they can do, and how they could go more aggressively. I got it. Great. I'll see you on the floor. Thank you. The next question is from Tal Liani of Bank of America Merrill Lynch. Please go ahead. Tal? The next question is from Marc Silk of Silk Investment Advisors. Please go ahead. Thanks for taking my questions. Excuse me. A lot of information there. The first question is on the European Tier 1 customer with 10 million users. Initially, how many companies were you competing with? I'm not quite sure which customer I mentioned with 10 million users, so maybe you want to refresh me. In January. There were two deals you mentioned in Europe. Okay. No name. Yeah. We didn't name the customer. You can tell us if you want. Not now. It's not my choice. It's not my lack of want. We were competing with at least two competitors on that deal. At least two. Was that the same for the other deal in Europe as well? I'd say that's a typical number. I don't want to now tell you if somebody else has a third or one less, but that's a typical number. That's pretty small. Basically, does that mean that there's not that many people that can do what you can do? Is that a good assessment of that? There are not many companies that do what we can do, or I would say there are not many companies at all in the network security, for CSPs to enable them to sell to the mass market, which is where we're in. Most of the security companies that are out there are focusing on the enterprise market, where we are, I would say, more unique and where we think that there's an interesting place in the market, is to enable telecom operators to provide Security as a Service precisely to the mass market, to consumers, to SMBs and so on. There are few companies like us that are targeting this exact segment. I believe that this segment is growing significantly now. Like I said on the call, I think that many operators are understanding that they need to provide this service. There aren't a whole lot of companies that they can go to to get technology and product to enable that. Which is good for us, of course. That's great information. Can you tell us why you were picked for those, let's just say those two recent deals. Why were you chosen? Again, it just gives us more light as far as how important you are or how different you are. Look, I think it's always a combination of several factors, right? I think one is the fact that we're really the only ones there today that offer a 360 holistic approach. If an operator works with us, he can see his path, not only with what he wants today. Say, an operator today says, "I want to launch Security as a Service to the mobile customers." If he works with Allot, he can see his path to now expand that service also to the fixed access market, to his fixed customers. He can see how he can add to that off-network protection. He can see how he can expand that to small, medium businesses. He can see how he can do all that with fundamentally the same user experience, the same threat databases, the same management system, et cetera. That's something that nobody else provides today. That's a very key differentiation, even if the operator wants to start with only one specific segment. That's one reason. Second reason is, specifically on mobile networks, what we do today with our NetworkSecure product is superior, simply provides a much, higher security level, better functionality, it's safer and so on, than what we regularly see as our competitors in that market, which is DNS-based security. It's also a better product. Third, we are focusing on this market to a large extent. Customers that talk to us see our commitment, our drive, the fact that we know how to help them in their marketing endeavors. We bring our marketing team as part of our value to show them how they can do better and what will work better, what will work not as good, and so on. Last but not least, today on network-based security solutions, we're a market leader. Which is also a good reason to choose us. Operators choose us for any kind of combination and different weights of all of these. That's a great answer. When you sign a deal, especially smaller companies, and you sign deals with Tier 1 companies, it gives you guys more legitimacy. After announcing those last two European deals, have you maybe seen some more interest in your technology? Or maybe somebody who you were talking with is now getting more, let's just say, aggressive because of those recent announcements? I can't tie it directly to those specific announcements. I can tell you, and I hope it came across in the tone of what I discussed during this call, that we are seeing a significant acceleration in the interest on behalf of CSPs in the last year, and specifically in the last few months. We're seeing that the interest in providing these services, the want to provide them, is definitely much larger than it was before. We're seeing a lot more engagement from operators that we didn't see before. Some of them, no doubt, as a result of, okay, they either talk to a customer of ours who's doing this, or they heard about it and this creates interest. I think most of it comes from the fundamental of the market, where they see the need to protect their consumers, they see the want from side of their customers to get that protection, and they see the need to monetize their network. That's what we're seeing. Okay. As someone personally who's invested in Israeli companies for, I don't know, more than 25 years, that was a nice development as far as the Arab, the opening new markets. The conversations you've had, what products are they kind of interested in? It's really across our product line. We're talking to them both on DPI products, on Security-as-a-Service products, where it's across the product line. Fantastic. You did mention, you had a conversation. I have to ask, just like every call I do. You talked about an American company who kind of now sees the Allot as a way to generate additional revenue. Was that just initial talks, or are you in an RFP, or any color you can give us, that would be helpful? Okay. I can tell you that we're in serious discussions with the operators. I do not know what the result of these discussions will be. I do not know if we will win anything or anything of that sort. I can tell you that compared to, say, even a year ago, when the discussions were more exploratory, now we see multiple American operators that think they need to do something from the network. That's about what I can say. Stay tuned, right. Okay. A few years ago, when your stock was $7, I said, "Maybe use some of that cash to buy the stock at $7." Now that it's more than doubled from all your hard work, I think it's nice to see that instead of artificially, I'm not flip-flopping, but at these levels, I like that you're taking some of your money and investing it in the company to have real earnings per share gains down the line, as opposed to just artificially generating earnings per share growth. The other thing is, a few years ago, and I'm not comparing you to Apple, but when Apple was really more of a hardware company and they went to services and their revenue didn't really grow, these analysts were re-rating it because of the more higher gross margin business was starting to evolve. Kind of, I see the same thing with you guys, is once you continue your recurring revenue model, I think that the street is going to re-rate you as well down the line. Just a great progress. I like how you're taking the long term, and continued success. Thank you. You're welcome. The next question is from Jacob Stephan of Lake Street Capital Markets. Please go ahead. Yeah. Hey, guys. Thanks for taking my question here on behalf of Eric Martin, Newsy. Just kind of wanted to drill down on the securities. Do you see that as a double-digit or more of a single-digit long-term growth? If you are referring to the SECaaS revenues. Yes accelerated growth. We said that our guidance for this year is between $6 million-$8 million. Next year, we are expecting at least $25 million. It's definitely more than a single digit. Even years after, we still see accelerated growth. This is the whole issue of such a rev share model. Okay. You guys had mentioned that you had two competitors kind of on the Europe deals. Are you typically competing with more than two competitors or less than two in all geographies? No, typically we find another two, maybe three competitors in a specific deal. If there's going to be four, it's really a lot of competitors, okay? I'm talking about security deals. Yep. Okay. Let's switch over to the DPI business. Where do you see the long-term growth rates for that? I think we continue to see at least, in the next few years, we're continuing to see something in the single-digit growth rate, not more than that, for the overall business. There will probably be some use cases may grow faster, some may grow slower. Overall, the whole market, we think it's going to grow single-digit. Okay. All right, I'll have back in mind. Thanks, guys. Thank you. The next question is from John Roy of Water Tower Research. Please go ahead. Thank you. When you were describing your perfect storm in 2020 of really drivers of growth, I was curious if you could give us a little color of what elements of that you expect to continue in 2021, and as an adjunct to that, is the peace accord going to be a substantial contributor in 2021 or is that more of a 2022 event? When I described the perfect storm, I think that's the situation that we're looking at now. I think that that's going to drive a new recurring security deal that will be signed in 2021. I see those trends continuing. With regard to the peace accords in the Gulf region, it's really a completely new region for us. This is unlike anywhere else in the world. This is not someplace that we were doing business in the past and that we know people and individuals and companies and so on, we're learning it. I can say again that the atmosphere was extremely positive and very acceptance. Now, is there something there that we can close already in this year, or is that going to wait for 2022? I'm not expecting that to make a material difference in 2021, because usually, working with operators takes time. Not knowing the Gulf region, not working with these operators in the past, I'm going to assume that they're like all other operators in terms of the time it takes to close deals, which means it probably won't have any material effect on 2021. I'm hopeful for the future. Yeah. It sounds like it might even slip into 2023, given how long it takes to sign a normal deal. That's true. Thank you for that. In the broader geography, if you were to put in 2021, what is the geography where you expect to see the most growth? That's hard to say. I think, look, it depends how you define growth. Look, EMEA is, and you can see it in our numbers, was our strongest geography this year. I would certainly hope and expect it to grow in 2021 and further on. I look at North America, our revenues are very small. It's easier to have a high percentage of growth on something that small. There is an opportunity in North America, but I don't know to answer you what we'll actually see. I can describe the potential as I did, and I hope that all the geographies will grow. John, I think it depends on the definition of growth, because there could be growth in terms of revenues. There could be growth in terms of MAR, which you see the revenues starting picking up maybe a year later. You can see growth in terms of bookings that will not be recognized as revenue. There are a few dimensions. Right. It's not only revenue. Yeah. If you sign one North American operator, it may take quite a while to get it going, but the MAR would be huge. Yeah. Also, as we said previously in the call, that it takes to close a deal with an operator, it takes more than a year. It can take 18 months, it can be even higher. Great. Well, that answers my question. Thank you so much. The next question is from Tal Liani of Bank of America Merrill Lynch. Please go ahead. Can you hear me now? Hopefully, I can Perfect. Thank you. Sorry, I don't know how to operate mute buttons. I have two questions. The first one is, you mentioned book-to-bill 0.8 for the year. I missed parts of your prepared remarks, maybe you explained it. Can you explain the basics why book-to-bill below one? Does it have to do with recognizing revenues ratably or something? Just tell us a little bit the story behind book-to-bill. I have another question, not related. Last year, 2019, the book-to-bill, if I recall correctly, was 1.63, which was extraordinary. We got a lot of bookings. This year, we said in the guidance for this year, we said the book-to-bill will be lower than one. This is why I mentioned that the book-to-bill for 2019 and 2020 together, it was 1.17. By the way, the book-to-bill for the last three years, 2018, 2019, and 2020, was 1.16. There are fluctuations. I know, but- Between one year to another, depends if you get the order. Sometimes you can get the order in Q4, a big order that relates to the next year, sometimes, a big order slipped from one year to another. Right. We're not talking about- But- We're talking about thousands and thousands of small orders. Yes. The only reason why I'm asking it is because book-to-bill is a reflection or it's a proxy for future business. The question is, the fact that book-to-bill was 0.8, and since we're always looking forward, does it mean that you're concerned with your visibility for 2021? Does it mean that there is a likelihood of having less confidence? I don't know how to phrase it, less confidence in the numbers for 2021? For 2020, we had a higher confidence in the numbers since the backlog was higher. Yeah provided now the guidance for revenue between $145 million-$150 million, we do believe this is achievable. This is our goal. Even though we don't have 100% visibility, we believe those numbers. This is why we provided as a guidance. Tal, I think we feel comfortable with the guidance we provided for 2021. We're entering 2021 with a pretty strong backlog. Remind me of the number. $110 million. With $110 million of backlog, most of which, or significant enough portion will be what is expected to be recognized in 2021, we're guiding to $145 million-$150 million. Now we feel really good with the guidance we gave. Got it. Second question is about the DPI business. Last year was a good year for DPI in general. There were some good quarters. Yeah. Now, when you look back in retrospect, can you explain the reason for the better-than-expected results for the year, kind of throughout the year? Was it related to COVID-19 by chance? When you talk to your customers, how would 5G impact DPI? Do you expect the relatively solid trends to continue into 5G, or is it still unknown at this point? I think that COVID, at the end, didn't increase the business as I had thought when COVID started. When COVID started, I thought that there would be, okay, a lot more working from home, a lot more bandwidth on operators and so on. They would need to buy more DPI systems, licenses, et cetera. That turned out to have a relatively negligible effect. They ended up buying a little bit more, but nothing really significant. No, that didn't contribute much. Actually, COVID, if anything, it contributed to postponing deals and delaying them, more than anything else. Now it's a guessing game, but if we didn't have COVID in 2020, the year might have looked better. I don't know for sure, but based on how I see the deals we're closing, there's a good chance it would've looked better without COVID. With regard to 5G, I think 5G will generate more interest for what I see it already generating more interest, and I think it will actually generate more business, mostly on the security side, both on providing security for the consumers and SMBs and on the network itself as a derivative of, or a partial derivative of our DPI technology on protecting the network itself. When we say protecting the network, that is protecting the use of IoT devices that, the millions of IoT devices connected to the 5G network, use of them as bots to attack somebody or something, or the ability to spread attacks in this very broad pipe so that 5G brings. Our ability to prevent that is a combination of our DPI capability and our DDoS prevention capability, and I think that there's going to be a lot more interest for that. We see that already, and I think that that's going to generate nice business for us, going hopefully also in 2021, but definitely going forward. Got it. Last question to Ziv. Ziv, just housekeeping item, how much money did you save in OpEx in 2020 from not traveling, not doing customer engagement activities, et cetera? Do you expect these expenses to come back in 2021? What's your plan for the year? We saved a few millions of dollars, but we decided to invest this money in other activities. Also for 2021, we think that part of those expenses, the level of expenses to travel and other things will be higher than 2020. Maybe not the same as 2019, but more than 2020. Got it. That's already embedded in. The numbers already. Got it. Okay, perfect. Thank you. The next question is from Shawn Boyd of Next Mark Capital. Please go ahead. That's so cute. Morning, gentlemen. I just want to jump in and summarize something off the backlog comments. You all are pointing to the book-to-bill, with a two-year average, and if I heard the comments correctly, even to a three-year average, which certainly makes sense. I've heard also that the pandemic and the reduction in travel and everything else has certainly impacted us a little bit on the Allot Smart side of the business, and hence our bookings were down in 2020 as expected. Can we assume there's some pent-up demand there, and that as we continue to progress, we should be able to see bookings growth here in 2021? We don't know. I think we'll have to see how this really progresses. I think that there is a strong demand, as I said. Will this translate into booking growth or not? I'd rather not comment on that at this point. At the beginning of 2020, we didn't see what COVID was going to do at all. Now in 2021, I can tell you that we still don't see what the effects are going to be of COVID, to what extent it's going to delay things, to what extent it's going to affect. I feel reasonably confident with the revenue guidance. I'm a bit more hesitant on bookings, so I'd wait and see. Got it. Okay. On the revenue guidance, this is not a question. This is more just a comment, and it's an appreciation from a shareholder. I'd like to commend you all for being one of the few companies in my portfolio that actually met your revenue guidance for 2020 that you gave pre-COVID-19. I think that as we look forward and think about what you're saying and what you have confidence in, that all helps us just a little. Well, thank you. Last question from me is on the January deal that you announced. There were 10 million subs. When we do rough math of 10 million subs at perhaps the equivalent of $0.50 a month, that could be, if I'm doing it properly, that could be MAR of $60 million on that single win. Am I looking at that properly? If so, is that all in the $180 million that you're targeting here in 2021? It's already included. The deal that we announced in January was signed in December, so it's already part of the $192 million MAR of last year. Regarding the calculation of the MAR, unfortunately, we cannot disclose the MAR of any individual deal. You know the formula, how it is calculated. It's a simple math. Right. I cannot disclose the real MAR of such a deal. Okay. I understand that on a single deal, and I appreciate the additional color about that being part of the 2020 deals. Maybe coming at this one other way, let's get away from specific deals and simply look at the entire $192 million in MAR that you just reported for 2020. What's the average monthly revenue share to the company from that $192 million in MAR that you're pointing to? Like we said, like I said in my comments earlier, I think that Well, I don't think. I can tell you that 30%-50% of the share of Sorry, I'll rephrase that. Of whatever the operator decides that he's going to charge his end users, roughly 30%-50% is a reasonable percentage of what Allot will get. I will remind you, though, that when we state the MAR numbers, those are the numbers of what Allot should get theoretically, if 100% of the end users of which the operator has actually signed up for the service. Got it. Okay. Last question from me, and I really mean it this time. I apologize for going over. On the increases in operating expenses, you've kind of got a tiger by the tail here in terms of the Secure offering and what you're doing on the security side and going after these. I think all of us thoroughly understand you trying to optimize that and take advantage of that and grow the business as much as you can. I'm also guessing that you've got an idea of what you're getting on those incremental operating expenses. I'm almost thinking about a return on investment, but maybe that's not the right way to think. For each incremental dollar that you take operating expenses up right now, can you give us a feel for what kind of a payback you're thinking about and what you see the market providing, especially on that Allot Secure side? That's it for me. Thanks so much. Unfortunately, we are not a project company. We are a product company. We invest in R&D, we invest in sales and marketing. Of course, we can leverage on those expenses if the revenue will really grow if there will be accelerated growth. It's not like a project, a specific project that I can tell you I invest $100, and I get a return of 50%. It doesn't go this way, because the R&D is generic, and the sales and marketing is across the board. It's not per project. It's very difficult to measure it this way. Right. Okay. Well, I had to try. I hear you. Good enough. Congrats on the continued execution, guys. Great to see. Thank you. The next question is from Alex Henderson of Needham & Company. Please go ahead. Yeah, I'll be very brief since we've run way over here. I just wanted to ask, as you look at the portfolio of potential transactions from Marc in 2021, how concentrated is that? Is that a large number of smaller deals? Is it a handful of very large deals? Is it a reasonable distribution? What does the distribution look like in terms of the size and scope of the number of deals you're looking at? I think we're looking at a reasonably broad distribution. There are some deals that are very large, obviously, not a whole lot of those. There are some deals of mid-size and quite a few that are smaller. We just make some factor analysis of what we think we can close. It's a pretty wide distribution. Great. I'll leave it, Lior. Thank you. Thank you. There are no further questions at this time. Mr. Antebi, would you like to make your concluding statement? Yes, thank you. On behalf of the management and myself, I want to thank you for joining us on this call, for your interest in the company, and your support of our business. We are unfortunately still not traveling, but we will be holding virtual meetings with investors. We'd be happy to meet with you that way. Please be in touch with our investor relations team to schedule that. Beyond that, thank you very much, and I look forward to talk to you next quarter. Have a good day. Thank you. This concludes the Allot fourth quarter and full year 2020 result conference call. Thank you for your participation. You may go ahead and disconnect.
