Ken Xie

Thank you, Anthony, and thank you to everyone for joining our call. We are very pleased with our excellent second quarter results, driven by our differentiated strategy and innovation, strong execution, and broad-based demand.

Billings grew 33%, while total revenue increased 26%, propelled by 52% growth in product revenue. Free cash flow more than tripled year over year to nearly $1 billion.

Based on this strong momentum, we have raised our 2026 guidance. With AI quickly reshaping the security landscape, I would like to offer another angle on the network security space and its trends.

By combining our secure networking and unified SASE pillar, which both run on the same FortiOS, to create what we are calling the SASE firewall. Similar to UTM, next-gen firewall replaced traditional NAT-based firewall 20 years ago, I believe this new SASE firewall, which addressed the fast-growing area of SASE, AI, and quantum, represent another massive opportunity for accelerated growth with a much larger total addressable market, as shown on the slides 4 to 6 of the investor presentation.

In the second quarter, Fortinet SASE firewall business grew 34% to over $2 billion, cementing our position as a top player in this space. What make Fortinet SASE firewall unique compared to other competitors' SASE and firewall solution is that we are the only vendor to develop all key component of SASE firewall in-house and integrate into a single operating system, FortiOS.

Furthermore, we have developed our FortiASIC technology and invest in our own global infrastructure to accelerate performance and lower the cost, making adoption and migration seamless for large global customer base, as shown on the slides 10 and 11. Another key advantage of our SASE firewall is that we are the only vendor offering an easily deployable on-premise sovereign SASE solution, together with cloud SASE.

As we announced yesterday, the new FortiGate 1200G, the next-generation SASE firewall that combined local enforcement with cloud-delivered security to meet evolving customer demand for data privacy, performance, and AI infrastructure management. We believe this have driven our strong product growth recently and has an addressable market that is approximately two to three times larger than the cloud-only SASE of competitor offering, and we continue to win SASE deal versus all of the top SASE competitors.

We also see strong demand across our other strategic pillar, AI-driven SecOps, which had billings growth of 25%, supported by over 20 AI-enabled solutions on our platform. As customers consolidate vendor and simplify operations, we recently launched FortiISOC, a new cloud-delivered AI SOC platform, and expanded our FortiEndpoint with new capabilities.

As organizations deploy and use AI tools throughout their operations, they realize they must modernize their security to handle the complex, high-speed threats of AI era. Fortinet is uniquely positioned here as our FortiOS platform and FortiASIC technology allow enterprise to securely scale their next-generation AI environment with faster and better protection and simplified operation.

Looking ahead, we believe the combination of AI-driven security demand, our integrated and accelerated SASE firewall platform solution, and our strong operating model position Fortinet well for long-term balanced growth with strong cash generation, recurring revenue, and a shareholder-focused long-term growth capital allocation strategy, while consistently deliver GAAP profitability. I would like to thank our employees, customers, partners, and suppliers worldwide for their continued support and hard work.

I will now turn the call over to Christiane.

Christiane Ohlgart

Thank you, Ken, and good afternoon, everyone. We delivered a strong second quarter, exceeding the high end of our guidance across billings, total revenue, operating margin, and earnings per share.

Our continued momentum reflects broad-based demand and strong execution across customer segments, industry verticals, geographies, and our integrated and innovative portfolio of solutions, further validating the strength of our platform strategy. Total billings grew 33% to $2.37 billion, driven by robust demand for physical infrastructure and related attached services across Secure Networking and Unified SASE.

We delivered exceptional billings growth across each of three our three pillars in the first quarter, followed by an even stronger accelerating growth rate in each of the pillars in the second quarter. Secure Networking billings grew 34%.

We saw persistent high FortiGate demand as customers expanded their network security, including operational technology environments, LAN Edge, and AI data centers. OT billings increased over 55%, reflecting continued adoption of our solutions in industrial environments with high contribution to growth.

We also saw outstanding strength in Unified SASE, where momentum built throughout the quarter, resulting in 35% billings growth. Adoption of FortiSASE within our install base increased to 90% of large enterprises.

Our success is highlighted by FortiSASE billings growing over 100%, benefiting from expansion sales across our install base, competitive replacements, and new wins with large enterprises. This momentum was driven by customers recognizing us for our continued investments into flexible deployment strategies for SASE, including our new SASE firewall strategy.

The SASE firewall natively converges firewall, SASE, and hybrid mesh capabilities to protect users, applications, and data across the data center, cloud, and remote workforce. Instead of juggling high-volume east-west traffic up to a cloud POP and back, it inspects and enforces security locally, while seamlessly leveraging SASE for outbound traffic.

Billings from AI-driven Security Operations grew 25%, driven by strong upsell momentum as our install base increasingly consolidates point solutions onto our broader platform. Turning to revenue, total revenue grew 26% to $2.05 billion, with product revenue increasing 52% to $773 million.

Accelerating product revenue benefited from strong FortiGate unit growth and an increase in ASPs as customers shifted towards higher-performing models. Customer investments to secure AI workloads and mitigate AI-related risks drove both new business and upgrade activity across our install base, supporting growth across hardware, software, and attached services.

Service revenue grew 14% to $1.27 billion, with growth improving from the prior quarter. Service billings growth increased 26%, and total deferred revenue increased 17%.

This quarter's improved service revenue alongside robust product momentum and operational improvements driving revenue conversion reinforces our confidence in the long-term durability of our service business. We believe the first quarter of 2026 marked the trough for our service revenue growth rate, and we anticipate a positive trajectory in our growth rates going forward.

Taking a step back, our results reflect strong ongoing momentum from the durable market themes shaping customer priorities. Today, bad actors are leveraging AI to automate and scale sophisticated attacks, increasing the speed and complexity of threats facing organizations.

Consequently, cybersecurity has become an urgent business priority with high visibility at the executive and board levels, driving faster investment decisions. In addition, regulatory activity requires companies to act.

In response, enterprises are increasingly upgrading their network security infrastructure to support the demands of AI-driven workloads and growing data volumes, more complex distributed environments, and the need for stronger network segmentation. Our strong second quarter results and outlook continue to reflect several important market dynamics, including the ongoing convergence of networking and security, increased investments to secure AI infrastructure, accelerating IT and OT convergence, and growing demand for high-performance security solutions that address evolving compliance and sovereignty requirements.

The sovereignty theme is especially concentrated in EMEA and across public sector customers globally, playing directly into our strong market position in the region and that customer segment. As we look ahead, we continue to see these market dynamics gaining momentum, supported by ongoing technology upgrades, vendor consolidation, and the continued expansion of enterprise attack surfaces across cloud, AI, OT, and critical infrastructure environments.

AI is becoming a dominant driver of security infrastructure modernization. As organizations move from AI experimentation and early adoption toward broader deployment, they require security platforms capable of protecting AI models and data sets, while securing large volumes of east-west traffic and enforcing zero trust segmentation across distributed AI workloads.

To navigate this growing complexity, customers are progressively looking for integrated platforms that provide shared telemetry, improved visibility, and reduced operational overhead. Fortinet addresses these evolving needs with a comprehensive strategy centered on three core areas: securing AI data centers, protecting AI-driven applications, and delivering AI-native security operations.

For example, a neo cloud provider offering hosted infrastructure for generative AI workloads selected Fortinet to secure AI data centers in an eight-figure win. This builds on a seven-figure deal we secured in the first quarter, further enabling the customer's rapid expansion.

They chose Fortinet for our strong price-for-performance advantage and our ability to deliver scalable, high-throughput security. This enables the customer to accelerate deployment of new capacity while maintaining consistent security and operational efficiency as demand for accelerated computing continues to grow.

This expansion reflects a broader theme we saw in the quarter with many AI data center wins from customers scaling their AI infrastructure. AI is creating demand for high-performance security solutions that serve as the foundation for secure, compliant infrastructure.

As organizations gain greater awareness of AI-enabled attack technologies, security teams are accelerating investments to ensure their infrastructure can deliver the performance and protection required for the next generation of threats, which also requires SASE technologies. To meet this critical need for high-performance security, Fortinet supports complex customer requirements through cloud-based, hybrid, on-premises, and sovereign SASE offerings, enabling organizations to deploy SASE in the environments that best meet their operational and regulatory needs.

Customer demand continues to grow with our flexible deployment approach, representing a meaningful differentiator. In a competitive displacement win, a global pharmaceutical company signed a seven-figure FortiSASE deal to secure over 45,000 users, replacing its incumbent SSE-only provider.

The customer chose Fortinet for our unified architecture and integrated platform approach across SD-WAN, next-generation firewall, and switching, which reduces complexity and delivers significant cost savings versus managing multiple point solutions. A key differentiator in this SASE win was our ability to extend security processing to the edge through our on-premises appliances, providing greater control, improved performance, and deeper visibility compared to a cloud-only architecture.

This deal validates our strategic rollout of FortiSASE Outpost, which is specifically engineered to bring local SASE enforcement closer to users and applications. This win also highlights our platform advantage, as we were the only vendor able to meet the customer's full set of technical requirements, while enabling centralized management, simplified operations, and enhanced end-user experience.

Beyond AI and SASE, OT security remains a critical business and board-level risk priority. The threat landscape has expanded beyond traditional OT environments into critical infrastructure, supply chains, and manufacturing operations.

With Fortinet's integrated platform approach, customers gain visibility across both their OT and IT networks. Consequently, we continue to see strong demand across our OT portfolio and related services, driven by the combination of increasing cyber threats, AI adoption, and geopolitical uncertainty.

In a seven-figure deal, a major utility organization selected Fortinet to support a large-scale communications modernization OT initiative, spanning thousands of distributed field locations. The deployment leverages our integrated FortiOS platform to enable reliable, secure connectivity for operational environments, while simplifying management and reducing infrastructure complexity.

This engagement demonstrates Fortinet's ability to support mission-critical infrastructure initiatives. Our strong results highlight our continued execution against the durable market themes shaping the cybersecurity industry.

This is reflected in our services acceleration in the second quarter and our improved services outlook for the year, reinforcing the compounding strength and high-margin predictability of our recurring revenue model. As organizations navigate AI adoption, expanding attack surfaces, evolving regulatory requirements, and complex infrastructure environments, we believe Fortinet's integrated platform approach positions us well to capture share, deliver sustained growth, and create long-term shareholder value.

Turning to margins and cash flow. Non-GAAP gross margin of 80.9% exceeded the high end of guidance, while GAAP gross margin was also strong at 80.2%.

Non-GAAP operating margin of 38% was a second quarter record, up 490 basis points. This performance exceeded the high end of our guidance, driven by stronger-than-expected revenue growth, disciplined cost management, and growing efficiencies from our AI initiatives.

Moreover, our GAAP operating margin of 33.7% continues to be one of the highest in the industry. The strong operating performance translated to the bottom line.

Non-GAAP earnings per share increased 41% to 90 cents, while GAAP earnings per share grew 44% to 82 cents, significantly outpacing our top-line growth, reflecting high-quality earnings, supported by disciplined stock-based compensation and continued capital return over the past year. Free cash flow more than tripled year over year to $966 million, benefiting from improved linearity, higher billings, and strong working capital discipline.

Adjusted free cash flow was $996 million, representing an exceptional margin of 49%. We repurchased 1.9 million shares of common stock for $146 million during the second quarter and 12.5 million shares for $973 million year to date, which represents an average price for repurchases this year of around $78 per share.

The remaining share repurchase authorization as of today is approximately $766 million. Now moving on to guidance.

As a reminder, our third quarter and full year outlooks, which are summarized on slides 23 and 24, are subject to the disclaimers regarding forward-looking information that was provided at the beginning of the call. Consistent with our disciplined and prudent approach to guidance, our strong first half of the year supports a higher full year outlook.

We are raising our guidance across all top-line metrics, including billings, revenue, and service revenue, as well as operating margin and earnings per share, while managing the remainder of the year on a quarter-by-quarter basis. This quarter's improved services revenue growth, along with a strong outlook, allows us to raise our service revenue guidance, reflecting a positive trajectory in our service revenue growth rates.

For the third quarter, we expect billings in the range of $2.25 billion to $2.35 billion, which at the midpoint represents growth of 27%; revenue in the range of $2.01 billion to $2.11 billion, which at the midpoint represents growth of 19%; non-GAAP gross margin of 79% to 81%; non-GAAP operating margin of 35% to 37%; non-GAAP earnings per share of 83 to 87 cents, which assumes a share count between 741 and 745 million; infrastructure investments of $100 to $150 million; a non-GAAP tax rate of 18% percent, and cash taxes of $100 to $130 million. For the full year, we expect billings in the range of $9.35 billion to $9.55 billion, which at the midpoint represents growth of 25%; revenue in the range of $8.02 billion to $8.18 billion, which at the midpoint represents growth of 19%; service revenue in the range of $5.18 billion to $5.22 billion, which at the midpoint represents growth of 14%.

We continue to expect service revenue growth to pick up in the second half of the year, driven by accelerated product revenue growth, a key leading indicator. Non-GAAP gross margin of 79% to 81%; non-GAAP operating margin of 35% to 37%; non-GAAP earnings per share of $3.41 to $3.47, which assumes a share count of between 741 and 745 million; infrastructure investments of $350 to $550 million; non-GAAP tax rate of 18%; and cash taxes of $400 to $450 million.

I now hand the call back over to Anthony to begin the Q&A session.

Anthony Luskey

Thank you, Christiane. As a reminder, during the Q&A session, we ask that you please limit yourself to one question and one follow-up question to allow others to participate.

Operator, please open the line for questions.

Operator

Thank you. If you would like to ask a question, please click on the raise hand button at the bottom of your screen.

When it is your turn, you will hear your name called and receive a message on your screen notifying you that you may unmute yourself. We will allow a moment for the queue to form.

Your first question comes from Saket Kalia from Barclays. You may now unmute and ask your question.

Saket Kalia

Great. Hey, guys, can you hear me okay?

Ken Xie

You're all good. Thank you.

Saket Kalia

Hey, excellent. Hey, thanks for taking my question here and congrats on another strong quarter.

Ken, maybe for you on that point. This is the second quarter in a row of accelerating billings and product growth.

We've all talked about things like AI data center, OT, and other trends. I'm curious, what do you think is driving the accelerating growth here, and just as importantly, how durable do you think it can be?

Ken Xie

Yes. I think it's a very good question.

We also spend a lot of time try to study whether it's a new market trend or it's a surprise or other things. We do believe the growth actually is a long-term for Fortinet.

Definitely you see the AI change a lot of our security landscape, and also with our kind of investment, from the ASIC chip, from our own infrastructure, from the R&D innovation, we also position much better than any of our other competitors. That's also the reason I kind of try to call a new term, which I'm not sure everybody will like that, is a SASE firewall.

You can see on the investor slides number 6, I believe. This new platform starting replacing the traditional next-gen firewall, and also replace a lot of single solution SD-WAN vendor, and also competing quite well with all the cloud SASE provider, which Christiane gave the example, in some global company, the cloud-only SASE solution cannot meet the customer requirement, which they need to have a data privacy, they need to process a lot of information locally instead of send to the cloud.

That drive the change in the whole landscape, and we do believe the growth is quite long-term, just like a 20 years ago, the UTM next-gen firewall replaced the traditional NAT-based firewall.

Saket Kalia

Got it. That's very helpful.

Christiane, maybe my follow-up for you, and hopefully your team has gotten you a little cup of tea or a cup of water there, but maybe the follow-up for you is, how are you thinking about the impact of price increases on your product growth for Q3 and Q4? Right, I think there have been a couple price increases, of course, to reflect, right, the higher input cost, but curious how you're thinking about the impact here as we go into the second half.

Christiane Ohlgart

We have approximately high single-digit impact built into our billings assumptions for the second half. It's very dependent on product mix and what is being sold, because yes, there were price increases, but they were not for every product and every service.

It really depends on what's going. This why also if you look back at my prepared remarks, we saw really good unit growth, and we saw good ASP growth from moving higher in the various product mixes.

That's a good sign also that the customers are preparing for more network traffic than previously, yeah.

Ken Xie

Also we kind of building the trust with our partner, with our customer. We just want to maintain the same gross margin.

That's where we kind of real-time adjust the price based on some component cost like memory. If the price going down, we also real-time dropping the price.

That's also we don't see any excess inventory or pull forward, because we told the partner customer there's no need to really take extra inventory. Also we have a policy, we tend to starting charging 90 days after shipment for some kind of service supporting.

That's where there's no incentive to keep the extra inventory.

Saket Kalia

Very helpful, guys. Thanks so much.

Ken Xie

Thank you.

Operator

Your next question will come from Shaul Eyal with TD Securities. You may now unmute and ask your question.

Shaul Eyal

Thank you. Good afternoon, everybody.

Congrats on the ongoing strong performance. Ken, I was listening to your firewall SASE commentary.

Maybe help us understand, and maybe it's building a little bit on Saket's question, or at least your reply, but maybe how AI is propelling the convergence of firewall SASE forward.

Ken Xie

AI definitely we see generate a lot additional traffic. If there's some study whether few weeks ago or a few months ago, the machine-to-machine traffic first time passing the human-to-machine or human-to-human traffic on the internet.

That's definitely the AI agent, a lot of other AI applications drive a lot of traffic. A lot of traffic actually within the enterprise, within some kind of data center.

Also the new cloud deal we mentioned in the last quarter, which is eight-figure deal, last quarter after the seven-figure deal, we do see that kind of drive a lot of enterprise customer, even service provider, to have a better visibility, better control management of this kind of traffic. That's also kind of I mentioned last quarter, is also kind of accelerate the convergence of network security.

Especially on top of that, there's a kind of zero trust initiative. That's where we see it's a starting change in the landscape of network security.

That's I call it a SASE firewall. It's more like a early day when Fortinet start like a 25, 26 years ago.

Initially, I call it like a antivirus firewall because that's the first firewall can do the antivirus. Then later, they call UTM or next-gen firewall.

That's all fine. I do believe the SASE, the AI, drive a lot of growth, especially within enterprise, within service provider.

Shaul Eyal

Understood. Maybe slightly more of a, I don't know whether philosophical or strategic question to you or Christiane.

Broad-based performance across the three growth pillars. Do you think customers are viewing Fortinet as a platform provider in a similar way they're looking at, say, the two leading platform providers right now, like Palo or CrowdStrike?

Is that a fair assessment?

Christiane Ohlgart

From the customers I talk to, it's definitely a fair assessment, yeah, because there is a combination of factors that they like about us. It's the integration of our solutions.

It's the one OS, but then it's also the cost benefits that we return to the customer from that making it much easier to operate. From that perspective, I think our customers definitely see us as platform providers,

Shaul Eyal

and

Christiane Ohlgart

they are constantly asking us to develop more functionality to expand,

Ken Xie

yeah. We are also very focused on the network security.

It's different than whether Palo or CrowdStrike. One is more endpoint side.

The other probably a little bit of everything, with endpoint, with security operation, with a lot of acquisition. For us, it's very focused on the network security, with internal R&D, and integrate, develop all these function for FortiOS.

Also a lot of long-term investment like FortiASIC, like our own infrastructure globally. All these we feel is really the focus, the long-term investment, starting to see the benefit compared to other competitors.

John Whittle

We also do see a lot of customers buy across all three pillars. We're kind of converging the first two, you could consider it two pillars.

We see a bunch of deals where customers are buying from the Secure Networking, the SASE, and the Security Operations pillar. I think that's indicative of the fact that we are a platform play.

We've got a really broad solution out there that customers like because, like Ken said, it's integrated well together. It was designed from the ground up to be integrated and work really well together.

I think that's a big competitive differentiator for us.

Shaul Eyal

Thank you for the color.

Operator

Your next question will come from Gray Powell with U.S. Bank.

You may now unmute and ask your question.

Gray Powell

Great. Thanks.

Just want to make sure, can you hear me okay?

Operator

Yep.

John Whittle

Yep.

Gray Powell

All right. Thank you.

Congratulations on the strong results. Maybe just to dig into some of the disclosures.

It was really great to see the acceleration in both Unified SASE ARR and billings this quarter. Is there any way to comment on what component within that category contributed the most to the acceleration?

Was it on the SD-WAN or the secure service edge side of the portfolio? Then, I guess, just my follow-up would be, are you seeing SD-WAN or the access part of SASE become a bigger consideration point in those discussions with customers?

Ken Xie

We see the FortiSASE more than double year over year. The SD-WAN also we see pretty strong growth because all other top five competitor all come from acquisition.

They all have separate approach compared to whether the firewall, SD-WAN, and SASE. They have to have a point solution run like a two, three different box to do what we can do in a single box, single OS.

On the other side, there's a new market, that's we call the sovereign SASE, on-premise SASE. Like the example we gave, it's a global pharmaceutical company, we're the only one can meet their requirement, have a data process locally.

They have a lot of confidential data, all this medical data, they have to process locally. The same time, they do have a global footprint and workforce.

They also have some kind of global access. That's where the solution we provide can have whether on-premise SASE, sovereign SASE, private SASE plus all the cloud-based, the global Fortinet infrastructure give them the best solution or give them the only solution actually they see on the market.

That's actually drive a lot of growth. SD-WAN we do see more replacing, taking market share from competitors, because I don't see any of them kind of keeping invest or develop the technology, which after acquisition is more challenging for them.

On the other side, we do see very strong growth, whether the SSE part, and also the sovereign SASE, and plus also AI kind of related security.

Christiane Ohlgart

ARR growth came from

Gray Powell

both

Christiane Ohlgart

attached and unattached solutions.

Gray Powell

Understood. That was great color.

Thank you.

Ken Xie

Thank you.

Operator

Your next question will come from Keith Bachman with BMO. Please go ahead.

Keith, your line is open. Please ask your question.

Keith Bachman

Can you hear me okay? Mhm.

Ken Xie

Yep, good.

Keith Bachman

Great. Christiane, first of all, I hope you feel better.

Second, on the services, when you indicated that services growth would increase through the year, I was hoping you could give a little bit of color on the distinction between FortiCare and FortiGuard. In other words, the support functions should increase because you have more firewall units in the field, and it's been going on for several quarters, so that should increase.

Is there any color you can give on the contributing factors to the increase in service growth? Is it both the FortiGuard and FortiCare part, or is the support sort of more weighted towards the increasing growth?

Christiane Ohlgart

It's both. It's attached services, which is FortiCare and FortiGuard, as well as also growth coming from SecOps, which is typically more unattached solutions.

We see good growth across both.

Ken Xie

Also it's a SASE firewall, we're also launching some new service like SD-WAN, and also some kind of AI-related security service could be part of the FortiGuard solution. That's where we see there's an additional service we can add on top of the traditional firewall and the SASE service, which will drive the new service business.

Christiane Ohlgart

Maybe to provide some more color, when we expand in customer deployments, and that's what I tried to point out in my prepared remarks as well, we really make sure we sell attached services, including respective FortiGuard services. Also

Ken Xie

the bundled service. The bundled service we launched like a few months ago see very, very strong growth, which bundled the SD-WAN, the SASE, all together, so that's is a very, very good drive for the service growth.

Keith Bachman

Great. Ken, my follow-up is for you.

On slide 17, you depict OT grew 56%, billings grew 56%. Maybe give a little bit of characterization about what's really driving the acceleration in OT and how durable is that?

If it was AI-based, it would seem that that has long-term durability, but just maybe flesh out a little bit on the why and the durability.

Ken Xie

It's really like a two, three factor. One is really we have invest in OT for very, very long time.

We don't see our competitor really much focus in this area. Also, recently there's a lot of growing in infrastructure build-out, utility, security, and all this.

That's also because the not only our long-term investment, but also technology like ASIC fit in the OT security quite well. That's we feel we have a huge advantage compared to any other competitors, and we continue to lead actually in field report, we're the only leader in the space, and we do believe will keeping growing going forward.

Christiane Ohlgart

Let me add some more color on the OT side. Critical infrastructure is being targeted quite a bit more than maybe years ago, and it hasn't had that much security in the past from a cyber security perspective, mostly because the critical infrastructure was not integrated into IT networks.

We see a lot of white space, to speak, from that perspective in this field. If you look at Europe, you have a lot of regulations, whether it's NIS 2 or others, that actually require critical infrastructure providers to secure their infrastructure and have good reporting, have supply chain validations, and so on for cybersecurity there.

There are a lot of drivers that make this a super durable and growth driver for us,

Ken Xie

yeah. We are probably the only network security vendor talk about OT security the last few years.

I have not heard our competitor talk about OT security yet.

John Whittle

We've invested... We think there's net-new logos there too, as well.

Yep. We've been growing this for years, and it's ruggedized solutions.

It's also on-prem solutions that are well-suited for OT environments, and it's integrated solutions that simplify the management. For example, our FortiGate integrated with FortiLink and access points and switches really is a solution that a lot of OT providers like a lot, and I think all this has culminated in this growth, that also industry analysts agree that we're number one in this sector.

Keith Bachman

Yep, perfect. Thank you.

Operator

Your next question comes from Meta Marshall with Morgan Stanley. Please go ahead.

Meta Marshall

Great. Thanks so much.

A couple of questions. Just in terms of customers changing traffic patterns with AI, just wondering if you could speak to whether some of the increases that you're seeing are due to kind of shortening refresh cycles as they need to kind of upgrade to the newest ASIC to accommodate that traffic, or just kind of how you are seeing that refresh behavior from customers?

Then maybe a second question just following up on that OT question that you just got. Just in terms of sizing, how to think about for an average data center, how we should think about kind of the OT attach rate, if there's just a percentage of a data center build that we should think of that is kind of security-related, that would be helpful.

Thanks.

Ken Xie

AI definitely changing some behavior, and also, I keeping saying AI actually accelerate the convergence of network security. Within enterprise, the customer definitely want to have a better visibility how this AI agent and all this AI traffic kind of behave, and the same thing for the service provider, the data center, all this neo cloud provider.

That's we see pretty strong we call the internal or we call the east-west traffic, which is mostly deploy internal inside data center, inside enterprise. That's actually our ASIC performance advantage is definitely position Fortinet much better than the competitors.

That's actually we see, you can see the both the strong product revenue growth and also the unit growth, which probably, I think if you compare to five refresh usually take about five years average for the box, but compared to five years ago, our product revenue all this thing probably tripled, and plus we have this 56% product revenue growth, definitely is a much bigger than just a refresh. That's what we feel customer starting replacing whether some traditional firewall and SD-WAN, some other one.

The reason I kind of combine the two pillar together, because they run the same OS, sometimes customer initially just buy for firewall, SD-WAN, and then they gradually enable SD-WAN, SASE. That's actually kind of difficult to category whether it's a SASE deal or it's kind of secure networking deal.

That's why I feel using the SASE firewall, which address is much better compare if with secure networking growth still kind of single-digit, but we grow like a 34%. The second question...

Christiane Ohlgart

The sizing of IT versus OT, it really depends on the industry. In some industries, the OT side could be much bigger, and other industries, the IT side is much bigger.

Ken Xie

Also especially when building the AI infrastructure, they probably more starting from building the utility, all this kind of the basic OT side, and then eventually what will kind of get a higher layer, all this kind of like a server, and then the model, the application. That's we do see the initial strong OT growth to in early stage of AI infrastructure build-out.

Your next question will come from Fatima Boolani with Citi. You may now unmute and ask your question.

Fatima Boolani

Good afternoon. Thank you so much for taking my questions.

Ken, I wanted to ask you a higher-level strategic question. Fortinet has done a remarkable job navigating through the supply chain environment, not only in recent memory, but also during COVID.

I wanted to talk to you and ask you about the collaboration with Intel, what the next phase of the network and security processor look like in collaboration with Intel, and how do you think that brings to you a more advantageous position as you think about the future iterations of ASICs, and how you can deliver them profitably, and continue to kind of navigate the current environment where cost inflationary pressures are extremely high. Then I have a follow-up for either John or Christiane.

Ken Xie

It's a great question. I think the reason from day one, 26 years ago, when started Fortinet, when we want to build ASIC chip, it's a network security need a much more computing power compared to networking and some other kind of security.

That's where, if we only depend on the general-purpose CPU, which we also use in together with our own ASIC, we feel is not enough, cannot process the data quick enough, or cannot add enough function to meet the customer need. That's where from day one, we starting invest in the ASIC chip.

It's one of our strategy, sometimes the payback may take a 10 years, but we feel after 10 years, we have a huge advantage. As I believe so far, we are still the only cybersecurity company develop our own ASIC chip.

The partnership with Intel also very, very significant, because Intel probably is the only manufacturing in the US, probably do to all this kind of chip manufacture. We have great partnership, and we do believe, combine the two company technology innovation, we can really bring this network security to the new level and also even can be expanding into the new space.

On the other side, yeah, we also feel network security will continue to expanding beyond the traditional enterprise, can be eventually go to now is with SASE can supporting remote work from home, eventually can be in the consumer, in some lot of broad area. The convergence of network security will keeping driving this space grow faster than the other area.

At the same time, the AI, we also see, it's a huge boost for the network security need, especially with a lot of new vulnerability discovery in all this software, and network security definitely give them another layer of protection and another layer of visibility control. That's we see I believe it's very, very important strategy to keep in investing in this kind of long-term ASIC chip, own the infrastructure.

That's what drive the long-term performance, and lower the cost, and eventually pass all this benefit to customer.

Fatima Boolani

I appreciate that detail. Christiane, you mentioned in your prepared remarks that the source of the operating leverage and margins outperformance was tied to the revenue beat, cost controls and rigor, and also some AI efficiencies.

I wanted to take a step back and ask you, over the course of the last 6 to 12 months, what have you done operationally at the company to allow for these types of efficiencies to become more prominent in your profitability profile? Specifically from a go-to-market, sales management, sales rigor perspective, could you talk to anything that you've been doing differently whereby your forecasting and your planning accuracy has increased, because the trend of results in the recent quarters has been consistently up and to the right, and certainly since you've come into the role.

I wanted to get more deeper, maybe granular perspectives on internally. The external market opportunity is very strong, but internally, how have you prepared with any metrics that you can share, in very nimbly responding to the very strong market and demand forces?

Thank you.

Christiane Ohlgart

I think it's a team effort across all functions, where we are leveraging technology, where we are leveraging also our internal AI build-out to develop additional solutions that help us with cost-effective processes and insights. That's what we're going to continue to do.

We started it years ago in the support organization, and we've seen good success there, with our significantly slower headcount growth or not even having to backfill certain roles in support. We're doing it across many functions to make sure that we are on top of technology trends, deploy them internally, and also mine our own data for better insights to make the right business decisions.

John Whittle

I think we also have a culture of being very disciplined, and also not really getting complacent when things are going well, and really buckling down. I think Ken spreads this culture throughout the organization.

Like Christiane said, it's a team effort to reinforce that. I think, when things are going well, we buckle down, and we don't want to get complacent on the sales and growth side, but also on the cost side.

AI helps us there, and other efficiencies and economies of scale can help there as well.

Your next question will come from Gabriela Borges with Goldman Sachs. Please unmute and ask your question.

Gabriela Borges

Hey, good afternoon. Ken, I wanted to follow up on your comments on how this product growth that you're seeing today is unlikely to be a function of pull forward.

I wanted to ask you and Christiane to comment a little bit on the visibility of the pipeline into 2027. I know we're still 6 months away from any sort of formal 2027 guidance.

We sort of have to dial in our model this evening on these 50% plus product revenue growth comps, and last quarter of course north of 40%. I guess, give us a little bit of direction here.

How should we be thinking about product revenue growth? It's a little bit similar to Saket's durability question into 1H '27 next year.

What is the pipeline telling you? I know in the past you've talked about that 10% plus industry growth rate and taking share on top of that.

Whatever you can tell us, early reads into how we should be modeling next year.

Ken Xie

It's pretty tough to predict the future, but maybe I try from two angle. One is really replacing some of the old infrastructure.

The other is really a new growing area. Definitely we see the traditional UTM next-gen firewall, and the SD-WAN solution, and even cloud SASE have their limitation.

We do see we kind of quickly gaining market share there, from the few case we won there, that's definitely we feel pretty confidence our product solution is much better, the customer partner would benefit a lot. On the other side, there's a new area, whether related to some kind of AI security, and the new infrastructure build-out, the OT, that's also we see kind of we position well.

It's a good kind of opportunity. We kind of closely engaged with, even for SASE, 3 years ago, we only focused on SASE for service provider.

Now we see they're all starting coming back with all this sovereign SASE, private SASE, and the on-premise solution is huge. That's the reason I say it's a two to three times larger than the cloud-only based SASE.

On the other side, we do see as long as there's the new trend keep growing, we do see we kind of keep again growing in this new space also quite well. It's probably a little bit too early to give any number on the 2027.

Maybe Christiane have better visibility.

Christiane Ohlgart

I think we are focused on the durability of our growth, and the themes that we're seeing, whether it's AI, whether it's SASE, whether it's OT, they will continue into next year, and then the regulatory activity in some parts of the world will continue as well. I think the question is how much share can we capture from others, and how much can we grow in our own customer base.

We will get you those numbers in January or February.

Gabriela Borges

That is fair enough. Thank you.

Our next question will come from Junaid Siddiqui with Truist. Please unmute and ask your question.

Junaid Siddiqui

Thank you for taking my question. Ken, you've talked about the sovereign SASE opportunity ultimately could be much larger than the cloud-delivered SASE, around two to 3x, as you just mentioned.

Much of that sovereign SASE opportunity seems tied to service providers deploying and monetizing their own SASE infrastructure. What are you seeing in the field that suggests providers are prepared to invest behind that strategy?

What are some of the factors that could potentially slow adoption relative to your expectations?

Ken Xie

I do believe a lot of service provider, they need to changing their security service go beyond the traditional some firewall, VPN service, and then that's definitely some of the SASE service is actually quite important for their customer. That's also they do have a infrastructure advantage if they can leverage their infrastructure deliver the SASE, would be more give kind of a better data privacy, better performance, leverage their local infrastructure, and at the same time, kind of a win-win situation for them and for customer, for us.

On the other side, a few years ago they're kind of a little bit slow, but now we see things accelerate. On the other side, we also see the enterprise also starting demanding this sovereign SASE, like the case we gave about this global pharmaceutical company.

They do want to have a SASE deployed within their enterprise, within their data center. That's where the on-premise solution also quite important.

That's also the product we announced yesterday, the FortiGate 1200G, we do put some a big percentage of content, emphasize how this all-toll SASE deployment is important for a lot of customer, because you can process all this data locally on the FortiGate, and at the same time, can also leverage some cloud, some management, to really enforce some policy globally. That's the solution we see also well adapt for the enterprise.

When they see this solution, they feel it's much better than the cloud-only, which they have to forward a lot of their data traffic to cloud to process. We do see it's a kind of huge market, both for the enterprise and for the service provider.

We also kind of working well with a lot of service provider, which we see they have acceleration of this kind of sovereign SASE deployment now.

Junaid Siddiqui

Great. Thank you so much.

Our last question will come from Joe Gallo with Jefferies. You may now unmute and ask your question.

Joe Gallo

Hey, guys. Thanks for the question.

Margin guidance was really, really impressive. Can you just kind of talk about visibility into that?

Do you envision any more price increases as it stands today?

Ken Xie

Actually, like I say, we want to maintain the same gross margin. The memory price kind of stabilized in the last few weeks, or even last few months.

We're do a monthly adjustment based on our costs, but we want to maintain the same gross margin, that's the policy. That's we feel, but like I say, it's a still single-digit impact of the business.

We do believe the bigger drive is really the new SASE firewall approach, which gave a customer much better solution, better local control of their AI, their data, and the same time, the new growing area like OT, like all this AI-related, we do see that's much bigger drive for the growth. We see that the SASE firewall could be the new trend to drive the growth in the next 5 to 10 years.

Then,

Joe Gallo

thanks for that. Just as a quick follow-up, product growth was very, very strong.

Just any sense of the different components of that, networking versus firewalls, how growth profiles were for each of those?

Ken Xie

FortiGate probably the...

Christiane Ohlgart

Fastest growing.

Ken Xie

The fastest growth among that.

Joe Gallo

Yep.

Ken Xie

That's also because FortiGate run the same FortiOS for both the traditional network firewall security function, the same time for like SD-WAN, for SASE. That's where sometimes a little bit difficult to category whether belong to Unified SASE or Secure Networking, because sometimes they may deploy as a Secure Networking first, but quickly ramp up to enable SD-WAN, SASE.

That's why I would like to call it SASE firewall, because the same operation system. FortiGate see the strongest growth.

Joe Gallo

Awesome. Thank you very much.

Nice job.

Ken Xie
