Doron Abramovitch -- Chief Financial Officer

Thank you, Anat, and thank you all for joining us. We reported today another good quarter with continued growing revenues and expanding margins. We are growing a strong year during which we delivered growth, profitability and cash generation exceeding our initial guidance for the year and above our long-term CAGR which we showed last year. Revenues for the fourth quarter were $63.8 million at the high end of our expectations, and up 9% year-over-year. Full year revenues were $234 million, and up 11% from 2017. Revenues from the Americas were 44% of total 2018 revenues and increased 5% from 2017.

Revenue from EMEA were up 34% and represented 32% of the total, and revenues from Asia-Pacific were down 1% year-over-year and accounted for the remaining 24%. For the full year, revenues from the enterprise vertical represented 69% of total revenues and increased 17% from 2017, and revenues from the service provider vertical remained at the same level as last year. Subscriptions, continued to be the fastest growing type of revenues. Recurring revenues that includes subscriptions and support represented approximately 64% of total 2018 revenues, compared with approximately 56% in full year 2017.

I will discuss now expenses and profit all in non-GAAP terms. Non-GAAP gross margin for the fourth quarter grew to 83% from 82.3% last year and full-year gross margin went up to 82.7% from 82.2% in 2017. Over the long term, we expect gross margins to moderately increase driven by economies of scales of our cloud operations, our utilization rate of our scrubbing centers and then increasing proportion of non-cloud subscriptions. However, product and geography mix differences from one quarter to another, can cause some fluctuations around the trend.

Q4, non-GAAP operating expenses were $43.2 million below our guidance, compared with $45 million in Q4 last year mostly due to a benefit from a stronger U.S. dollar compared to last year and ASC 606 impact. We continue to invest in our business selectively and moderately to support our growth on the one hand, while delivering operating leverage on the other end. We are very pleased with the balance between these two metrics in last couple of years.

Our non-GAAP operating profit in Q4 2018 was approximately $9.8 million representing a 15.4% margin, which was up from 5.2% in Q4, 2017. Full year 2018 operating profit was approximately $21.6 million, up from $3.8 million and operating margin was 9.2%, up from 1.8% operating margin in last year. Non-GAAP tax rate was 11% for the year, down from 18% in 2017. Tax rate was lower than last year due to impact of the lower federal tax and adjustment related to ASC 606.

For 2019, we expect the tax rate to be approximately 11%. Q4 non-GAAP net income was $11.4 million or $0.24 per share diluted exceeding our guidance for $0.16 per share to $0.18 per share. The strong non-GAAP EPS was driven largely by strength in revenues and gross margin, expenses discipline and stable headcount as well as lower tax rate. Revenue growth affected EPS by approximately $0.01 to $0.02, tax and financial income by another $0.02 and the rest of the upside came from OpEx. Non-GAAP net income for the full year was $26 million or $0.55 per share diluted well above the net income and EPS for 2017, which were $7.6 million and $0.17 respectively.

Turning to balance sheet and cash flow. As subscription continued to be main growth driver, it positively impacted our total deferred revenues. We ended the year with a balance of approximately $167 million, up 13% from December 2017.

Our business mix provides us with visibility for future financial performance. In the coming 12 months we will recognize as revenues, approximately $105 million out of the December total deferred revenues balance or 63%. This compares with $91 million or 62% in Q4 last year. We had a very strong collection from customers in Q4 and we generated approximately $26 million of operating cash flow in the quarter, and more than $49 million in the full year, up 57% from last year. During Q4, we executed on our share buyback program and repurchase approximately 200,000 of our own share in the amount of $4.3 million. We ended the year with approximately $401 million in cash and financial investments, up from $344 million as of the end of 2017.

In early January we announced the acquisition of ShieldSquare, a leader in bot mitigation, were we discuss this acquisition in more depth shortly. We expect the acquisition to close at the end of Q1 and the total cash consideration that we will pay will be up to $18 million and part of it will impact the Q1 2019 cash flows. There will be approximately 70 people joining us, the vast majority of them are based in India. We expect the acquisition to be immaterial for 2019 revenue and dilutive to our fully diluted 2019 non-GAAP EPS by $0.09 to $0.10 starting in Q2.

And now to our outlook for the first quarter of 2019 we expect Q1'19 revenues to be between $58.5 million and $60 million. Non-GAAP gross margin to be approximately 82.5% and non-GAAP operating expenses to be between $44 million and $45 million. We expect tax rate to be approximately 12%. Non-GAAP EPS for Q1 is therefore expected to be between $0.12 and $0.13. This guidance assumes closure of the ShieldSquare acquisition at the end of Q1, so we didn't take any EPS impact for this quarter. I said from Q2 we expect the EPS to be impacted by approximately $0.03 per quarter.

As for our outlook for the full year of 2019, we expect it to be in line with our long-term model, which we present in last year of 9% revenue CAGR between 2017 and 2020. On the back of our strong 2018 revenue growth, we expect revenue growth in 2019 to be between 7% and 9%. The midpoint of this range leaves 2018 revenues, slightly above the CAGR rate from 2017.

We will provide a more detailed 2019 guidance in our Investor meeting in New York on February 20. I will now turn the call over to Roy.

Roy Zisapel -- Chief Executive Officer and President

Thank you, Doron. We are pleased with our performance in the fourth quarter and full year 2018. Second quarter revenue closed the record year, reaching $234 million. In addition, we had significant profitability improvement, net profit rose to $26 million and more than tripled from 2017. Record operating cash generation in the fourth quarter led our cash level to $401 million at the end of the year.

We also had record quarterly booking in the fourth quarter, which is reflected in the double-digit growth in total deferred revenues up 13%. Overall in 2018 we continue to execute our strategy and deliver on our goals. We have full confidence in our competitive position, given the breadth and maturity of our solution portfolio and in the preparedness of the organization for the coming year.

From a geographic perspective we are very pleased with our underlying performance in the international markets, EMEA and APAC. In the Americas, we were able to grow our revenues against the strong 2017. And in spite of some signs of softness in this region, specifically in the Tier One carriers. Overall, in all aspects and in all geographies we believe we are in a better position today than we had ever been. Let me briefly discuss what we are witnessing in our market data center and cloud application delivery and security solutions. Customer priorities are strongly linked to the ongoing transition of applications to the cloud and a very dynamic cyber security space.

Our offering is very much aligned with these needs, while market leading attacking litigation capabilities and superior quality of the deductions. We have a complete offerings spanning the private, hybrid and public cloud data centers coupled with fully managed service offering. The quality of our offering means that we simply provide a higher level of security, because of that we are successful with the most demanding customers with unique and complex requirements that often lead to relatively large deals. Consequently, our subscription solutions enjoyed strong growth in 2018.

Among our new logos acquired, (inaudible) our global top three car manufacturer, a global top three pharmaceutical company as well as banks, carriers, retailers and others. An example of the quality of our security portfolio is our emergency response team active attacker subscription, which is using intelligence from our Radware Deception Network of honeypots, we deployed across the world.

We are using this network to identify and block known attackers before they even reach the customer network. We just see fantastic feedback from customers who subscribe to this services. For example, a financially institution in EMEA shared with us that in October 2018 alone, they witness 3.7 billion package and two terabytes attack volume being mitigated with zero latency through the ERT Active Attackers mechanism before our devices has even begun processing any traffic.

In early January of this year we booked our largest to date. Active Attackers subscription deal with a long-term customer who upgraded their protection package to include the subscription for more than $500,000. Another example for the strength in our subscription business in the fourth quarter comes from a cloud security win in a leading European bank. The bank held our DefensePro Attack Mitigation Device installed in its data centers and then always on cloud DDoS protection service from one of our competitors. With experienced many DDoS attacks in the past, which were at times not mitigated by its existing always on cloud protection and we're only blocked by our own brand attack mitigation devices.

Unfortunately, due to the failure of the always on the cloud protection service, when these attacks became large enough to overwhelm the internet link, the bank service was disrupted. The bank's zero tolerance toward such attacks and the Israel inflation that the existing solution was unable to keep up with the rapidly evolving legal (ph) threat landscape, lending to seek a solution that will protect it in full, always. This multi-year deal was one of our largest cloud security deals to-date. As we announced last month, we further expanded our portfolio with the acquisition of ShieldSquare, a leading both in bot mitigation.

Today, more than 50% of the Internet traffic comes from bot and therefore organization in bot management solution does not only detect and mitigate bot attacks but also distinguish between human traffic, good bot traffic and bad bot in real time. The ShieldSquare solution does so by applying strong machine learning to analyze behavior and by creating advanced fingerprinting based on hundreds of parameters.

The solution protects websites mobile applications and API and provides an important expansion of our attack mitigation capabilities. To summarize, we are in an excellent position in all aspects of our business and we make consistent progress on all dimensions of our strategy. Financially, we enjoyed revenue growth and increased profitability in line with our three year model affirming our confidence in our strategy. Our portfolio is the widest and most advanced it has ever been, reflecting thought leadership in a close alignment to customer needs.

The cloud environment creates new security challenges. We will continue to leverage our advanced algorithms and machine learning capabilities. We introduce additional solutions for this environment. We look forward to continue growing our business in 2019 and beyond.

And with that I will now open the call for Q&A.

Questions and Answers:

Operator

(Operator Instructions) Your first question comes from Alexander Henderson with Needham & Company. Your line is open.

Alexander Henderson -- Needham & Company -- Analyst

Thanks. Congratulations on the nice quarter. I wanted to ask you a couple of quick questions on mechanics. So can you give us sort of the -- the current headcount and I didn't catch the book-to-bill?

Doron Abramovitch -- Chief Financial Officer

Okay, so, hi Alex. So it's in the same level in last few quarters approximately 970 people that we now hire. What I meant, when I said the stable headcount. And as for the book-to-bill, its -- Roy, had mentioned it in a different way -- it was a -- in this quarter it was significantly more than one.

Alexander Henderson -- Needham & Company -- Analyst

And then you talk about the staff and service revenues being 64% in '18. Do you have a metric of how much you think that might reach over the course of '19. Are you anticipating continued growth in deferred revenues in '19, hence overall our order growth in double digits?

Doron Abramovitch -- Chief Financial Officer

Yeah, so, we don't give the specific metric, but given the strength in subscription we're seeing, and the fact that we're moving more and more products and solutions to this business model, we obviously see growth, or we expect growth in '19 in the total deferred balance. And we will continue probably to see rise in the percentage of that -- of our total revenues, up from the 64% we had for '18.

Alexander Henderson -- Needham & Company -- Analyst

I just wanted to talk a little bit about ShieldSquare with you guys for a second. First off, congratulations, it's great acquisition superb positioning of that company. It's been a bunch of time talking to some of their competitors and most of the competition looks like it's growing in the order of 30% to 50% as bot attack metrics become really the most critical element of CDN protection and SaaS protection. So to that extent how rapidly do you think you can take this bot protection capabilities, back to your SaaS customers, back to your service provider customers and monetize the business, and maybe immaterial now, but what does it look like in terms of the ramp?

Doron Abramovitch -- Chief Financial Officer

Okay, so, that the only comment, assuming we're closely toward the end of Q1, but believe it will take us between three to four months to integrated into our cloud offering. So our plan is by end of June to have it integrated into our cloud security solutions. And as you mentioned, we think it's an important addition to our cloud security portfolio. We think this plays extremely well with our DDoS, WAF and now the Anti-Bot capabilities and we believe customers and that's the feedback we were getting so far and from a customers and prospects we were discussing this acquisition, where we will find it very beneficial to get unified complete application security solution from us. So we're entering this market early on and we are looking to gain a very strong position there.

Alexander Henderson -- Needham & Company -- Analyst

Okay, and would you think it in 2020 that you might be able to fully offset the dilution and have it contribute to earnings or how should we think about the fallout of the dilution from it?

Roy Zisapel -- Chief Executive Officer and President

Alex, we will probably show some more information in the Investor Meeting, but we do assume that it will be accretive in a way -- its to early, but we need -- this is the time right now.

Doron Abramovitch -- Chief Financial Officer

That's a safe assumption.

Alexander Henderson -- Needham & Company -- Analyst

Great. I'll see the floor. Thank you very much.

Operator

Next question comes from George Notter with Jefferies. Your line is open.

George Notter -- Jefferies -- Analyst

Hi, guys, thanks very much. I guess, a few areas of questions, maybe first we could just talk about the average duration of the total deferred revenue, I know in times past you guys have given us that number in terms of the years. Just want to make sure the growth in the deferred revenues is -- I guess coming more naturally rather than just extension of services contracts?

Doron Abramovitch -- Chief Financial Officer

Okay. So in terms of the numbers, its quite stable in last -- I think 2.5 years since we started to disclose this, so it's approximately 1.8 year, so the -- the average duration of the contract that are right now in the total deferred revenues. So, as Roy mentioned assuming that we will continue to grow, I believe we take the assumption that we will continue to be in this level of a 1.8 years.

George Notter -- Jefferies -- Analyst

Okay, that's helpful.

Doron Abramovitch -- Chief Financial Officer

In the last quarter the duration is short and actually the growth you're seeing is in a shorter duration of new bookings and you can see that also in own comments, when you mentioned the percentage of recognition in the coming 12 months has gone up by like 1% from 62% to 63%, that tells you the duration that shortened.

George Notter -- Jefferies -- Analyst

Okay, great, that's helpful. And then the 64% of revenue coming from recurring sources, that's an impressive number. Just out of curiosity, could you share that number for Q4? I presume it was higher as you exited the year, is that fair?

Doron Abramovitch -- Chief Financial Officer

No, unfortunately, we don't share it.

George Notter -- Jefferies -- Analyst

Okay. No worries, that's fine. Maybe just stepping back just more intuitively -- when you go and talk with enterprise customers and you sell deals and is it fair to say that higher percentage of those deals are coming in the form of subscriptions, non-cloud type subscriptions. And I guess I'm just curious about what's driving that why our enterprise is more interested in constructing deals that look like that?

Doron Abramovitch -- Chief Financial Officer

Okay, so, couple of points. Number one, I think, Roy mentioned that subscription is the fastest growing component of our business, well definitely we're seeing the trend. The trend going there and as we discussed in previous calls, we have multiple sources today of subscription, some are coming from product subscription basically capabilities that we used to sell its perpetual or new capabilities we are bringing to market, and they are only available now in a subscription form. Those are generally capabilities that our add-on or extensions of our product capabilities.

I've mentioned, for example, The ERT Active Attacker Feed, it's exactly that. When you want this capability of blocking known attackers based on cloud intelligence in your product, you need to subscribe to this add-on capability. And like that, we have a growing set of subscription across both our ADC and security product lines. The second source of subscriptions is all the cloud. The cloud delivered services, the cloud DDoS, the cloud WAF and now it will be also the Anti-Bot and we're seeing very strong growth there as well.

And last but not least, all the managed services. There is a major issue of expertise in customers around cyber-security and we're seeing them more and more subscribing to a managed service ERT, Emergency Response Team under attack services, et cetera, et cetera renew up the yearly services. So I think if you look on the underlying drivers for the customers to move to subscription. Number one is the cloud, they're getting used to consume cloud services and now -- and as it relates to us, our cloud services. Number two, the lack of expertise move them to source or to outsource some capabilities from the outside.

And last but not least, as long as we continue to deliver innovative solutions that have clear value, like I've mentioned with this example, although we have several of these that are extremely successful. Customers are buying into it because of the value.

George Notter -- Jefferies -- Analyst

Yes, that's great. And then just one final question, I just wanted to ask about OEM customers. I think you guys mentioned one point last year that you expected to sign a new OEM coming through the end of the year, but I'm just curious about where that is right now?

Doron Abramovitch -- Chief Financial Officer

Yeah. So, we did sign, it did contribute to revenues in '18. The public announcement depends on our partner and they're not ready yet to do that, but we've execute that and started to contribute to the number.

George Notter -- Jefferies -- Analyst

Thank you.

Next question comes from Tavy Rosner with Barclays. Your line is open.

Peter Zdebski -- Barclays -- Analyst

This is Peter Zdebski on for Tavy. I just looking at the Americas growth of 5% for the year, we've understood that subscriptions and deferred growth was stronger than the Americas in the past. Could you give us a sense of how the deferred balance looks in the region -- in light of that 15% growth in total deferred for the year.

Roy Zisapel -- Chief Executive Officer and President

Yeah, so we don't break it by region, but so I don't want to go into specifics, but overall in the cloud adoption in North America is the highest, after that is EMEA and then APAC. Those are global trends, we would see similar aspects of that also in our -- in our bookings.

Peter Zdebski -- Barclays -- Analyst

Okay. And just one follow-up on OpEx, you mentioned that the stronger dollar was a factor in the OpEx declined in the quarter. Do you have a sense of what the growth in R&D and sales and marketing spend would have been on a constant currency basis?

Doron Abramovitch -- Chief Financial Officer

So, If I compare this quarter to 2017, there will be -- OpEx was down by $2 million out of it, there is something that $600,000 is shekel mainly to the R&D. And if I the compare it to Q3, or let's saw we added $700,000 the vast majority from marketing, sales and marketing activities and a very small portion is the FX. So these are the numbers, if I compare to these two periods.

Peter Zdebski -- Barclays -- Analyst

Thank you.

Next question comes from Ittai Kidron with Oppenheimer. Your line is open.

Ittai Kidron -- Oppenheimer -- Analyst

Hi guys, good quarter. Couple of questions Doron, I just want to make sure when you saw 64% including maintenance and subscription revenue. Is that correct?

Doron Abramovitch -- Chief Financial Officer

Yes.

Ittai Kidron -- Oppenheimer -- Analyst

Is there a way to give us more color on the subscription component itself. Again, it's just -- it's hard to get your hands -- our hands around what is the maintenance part, which I assume is probably the majority of the 64%, the relative growth rates of the maintenance versus the subscription. Is the maintenance even growing?

Doron Abramovitch -- Chief Financial Officer

I'm not sure that -- that your conclusion is definitely correct because three years ago it was 42%, and so the growth comes from all the business trends that Roy mentioned regarding the subscription and now it's down to be 64%. Unfortunately, we don't break it quarters-by-quarters from -- and we don't break it in other ways -- between the subscription and maintenance, but you can assume that the growth comes mainly from subscription.

Ittai Kidron -- Oppenheimer -- Analyst

Okay, very good.

Doron Abramovitch -- Chief Financial Officer

Let me phrase it a bit differently -- it look us like 15 years to build a maintenance base of high 30's, low 40's so to speak. And if you look on all our finances and you know them for many years. And then if you look at the last three years that figure moved once we started with the subscription from 40% to 64%. It's clear where the majority of the growth is coming from.

Ittai Kidron -- Oppenheimer -- Analyst

Yes, I just think you're doing yourself a little bit of disservice by not splitting it up because my gut tells me is that your maintenance revenue Roy, even though it took you to 15 years to build over it, and at this point is probably flattish. So the growth would have been even nicer even more transparent if for just split them up in my -- at least directionally correct in how I am thinking about this?

Roy Zisapel -- Chief Executive Officer and President

I don't want to say maintenance is flat, et cetera, but again subscription is the driver, absolutely on that you're right.

Ittai Kidron -- Oppenheimer -- Analyst

Okay, excellent. Now, regarding the enterprise revenue, the split there it's somewhat low on a year-over-year basis in this fourth quarter. Why would have expected some budget flush to work its way, after multiple core, as a very strong year-over-year growth. How do I get my hands around, what's going on to the enterprise and you had talked about some softness. I just want to make sure, in my understand what did specifically relates to?

Doron Abramovitch -- Chief Financial Officer

The softness I talked about was mainly relating to U.S. Tier One carriers. Enterprise trends were very good in the quarter especially on the -- on the booking side, we're very happy with the enterprise business and the trends there. That's where most of the subscription business is going and in the trends are all strong.

Ittai Kidron -- Oppenheimer -- Analyst

Okay, very good. All right. Good luck, guys.

Doron Abramovitch -- Chief Financial Officer

Thank you.

Roy Zisapel -- Chief Executive Officer and President

Thank you.

Next question comes from Zach Turcotte with Dougherty. Your line is open.

Zach Turcotte -- Dougherty & Co -- Analyst

Thanks. Zack on for Catherine Trebnick. First, just kind of a follow-up on the Americas growth, just under 5%, I know it fluctuates quarterly, but how much of this -- do you attribute to the softness in the carriers versus just tough compare. How much do you see that rebounding in 2019, are you already seeing any sort of bounce back.

Doron Abramovitch -- Chief Financial Officer

So, no overall I see -- I see those three factors. One is the tough compare like you said, Q3 last year, we went up 33% in Americas Q4, 27%, so like H2 was like 30% it was very low, that was a relatively high bar. Second, is the Tier One carriers, we don't think it's -- it should be long-term, we have very nice projects and so on, but we did see delay, definitely, in Q4, some a bit before that. And the third is our execution. There's always room for improvement, I think we can grow faster, I think we have -- based on the middle of comments I shared with the you, a very strong portfolio position and those things that we always need to improve in our own execution. So those are the three factors, that I think led to this result.

Zach Turcotte -- Dougherty & Co -- Analyst

Okay, great. And then you had pretty consistent being raises throughout 2018, so even despite strong cost controls and sales and marketing as a percentage of revenue. Even declining pretty sharply. So, I'm wondering, are there a different direct sales efforts or channel efforts that you're using to drive the (inaudible) raises. Do you attribute some of this too material revenue from OEM partners that you're finally seeing or what's the main driver of these (inaudible) raises consistently?

Doron Abramovitch -- Chief Financial Officer

It's a combination, I think of many factors. It's the portfolio, it is the trends in the market that are playing to our favor, they move to cloud, the cyber security becoming more and more critical. And I think in the OEM's are obviously assisting us in penetrating new customers, some of the new strategic alliances. But all in all, I think it's consistent execution of this strategy, we shared and starting two years ago in more details in the Analyst Day, a year ago we're doing that. It proves itself, and I think we're starting to see the fruits.

Zach Turcotte -- Dougherty & Co -- Analyst

Perfect, thanks.

Next question comes from Josh Tilton with Berenberg. Your line is open.

Joshua Tilton -- Berenberg Capital Markets -- Analyst

All right, thanks for taking my questions. Can you talk to the types of customers you're seeing adopting with cloud deployments, beside from the hybrid deployments, you are seeing a situation where the cloud maybe opening up an opportunity for new customers, possibly couldn't afford and manage solutions prior?

Doron Abramovitch -- Chief Financial Officer

Yeah, absolutely. I will give you one prime example. I think it's the cloud web -- the cloud web security. In the -- Web application firewalls are not new to the market, but they are considered to be very complicated to manage, you need to understand security applications and every time, is the new application version or capability going out and with DevOps now, its starting an agile, it's becoming a weekly, the release cycle, you need to adjust your web security to do that. That creates a huge cost and operational building on even the largest customers, not to mention, our mid-size customer.

Now, I can assure you that all the customers that -- internet facing application must have a web security solution, many of them simply cannot afford the complexity and the cost. The Cloud WAF is opening up this opportunity for us and we are seeing very, very, strong growth there and I think this growth can last for years to come because it's one -- on one end, like I mentioned, the critical need of the customer. Second, is the clear displacement of on-prem WAF appliances that are moving to the cloud because of the security cost and operational benefits.

And third because you can build a very, very strong, offering for example, adding Anti-Bot through the mix. So, definitely we're seeing new markets opening up for us, because of the cloud delivery and we are trying to execute as fast as we can on this opportunity.

Joshua Tilton -- Berenberg Capital Markets -- Analyst

Thank you. And then just on ShieldSquare. So my understanding is that your security capabilities had bot mitigation capabilities, especially around the issue of the dynamic IP address associated with the bots. The ShieldSquare just strengthen those capabilities, or does it bring additional security capabilities of the portfolio.

Doron Abramovitch -- Chief Financial Officer

Yes, it's much deeper. When you want today to protect against sophisticated bot, it's not enough to look on the IP address, been the sophisticated bad bots of replacing them. The attacks like accounting closer or attacks from the inventory and so on, a way more complicated and, for that I mentioned in my comments, you need much broader, stronger algorithms, machine learning, hundreds of parameters per session that you take into account to distinguish. Again, it's not only between human and bots, you need to differentiate also the good bot, like search engines, like performance monitoring and so on. Partner API systems, so its really the ability in real-time to differentiate between the good bot and bad bot and human. And, I think we are very happy with the acquisition, and we believe we will see a significant contribution to our cloud-based services with it.

Joshua Tilton -- Berenberg Capital Markets -- Analyst

Thank you. And then just last one, I believe Cisco added your cloud solutions to its reseller portfolio in Q2. Can we get any updates on how that's going for the business?

Roy Zisapel -- Chief Executive Officer and President

It is progressing. For example, one of the wins that I've mentioned on the pharmaceutical top three companies that we won was done through Cisco just as an example.

Joshua Tilton -- Berenberg Capital Markets -- Analyst

Okay. Thank you.

Your last question comes from Alex Henderson with Needham & Company. Your line is open.

Alexander Henderson -- Needham & Company -- Analyst

Thanks. So I was hoping you could give us some granularity around your penetration of the SaaS customer set, going in and selling to the sales forces of the world. And to what extent, if you could (inaudible) CDN in there? That would be quite helpful?

Roy Zisapel -- Chief Executive Officer and President

Yeah. But I think at the very high end we're starting to be, with very nice market share, but the SaaS market is huge and -- the amount of companies is growing by the day. We have significant advantage there, technology advantage there that we are utilizing and we're winning more and more of these, but at least at the high end, we have excellent references, very well recognized names out there.

Alexander Henderson -- Needham & Company -- Analyst

One of the other questions, really underneath the surface is what's going on between the security portfolio in the traditional businesses. I assume that the traditional ADC market is fairly flat -- and fairly flat in your business. Is that an accurate baselines.

Doron Abramovitch -- Chief Financial Officer

We don't break it, as you know, Alex. However, I think the -- there is more strength in the ADC market than people give it credit.

Alexander Henderson -- Needham & Company -- Analyst

If we were to look at just the, the last portion of the business. I assume that in terms of orders coming in, is delivering something in excess of 20% type clip. My assumption is the --that the -- now when your products and more advanced products that you've added to that are growing faster and the DDoS is probably around 20% as well. Are those kind of the right mechanics around the security portfolio set.

Roy Zisapel -- Chief Executive Officer and President

We don't break it to that granularity but, as Doron mentioned subscription in the overall, obviously cloud is a major part of it. It is the fastest growing component of our business, if the average does, it did like this year, to 11%. You can assume the substantial growth in our subscription business, and also in cloud, obviously.

Alexander Henderson -- Needham & Company -- Analyst

And just to go back to Cisco, for one second, if I could. Any thought on actually getting some license and come out of that partnership with them? Or is this just Waiting for Godot kind of -- I mean, how long have we been talking about this, it's getting on three years, I think.

Doron Abramovitch -- Chief Financial Officer

Yeah, it's progressing, we always want more, but it is progressing and we're looking for '19 again to bid that business, but we are not looking into a licensing deal. We are looking for more and more of our solutions being sold by their sales force.

Alexander Henderson -- Needham & Company -- Analyst

Right, but didn't you have a licensing deal with respect to the software incorporated onto their boxes.

Doron Abramovitch -- Chief Financial Officer

Yeah. So so it's an OEM deal, where whenever they sell it, we get the license, so absolutely. But it's not like a onetime software license. Maybe I didn't understand your question, being that we had with them.
