By 2001 attacks no longer came only through open ports: the Nimda worm spread at once through email, infected web pages, shared folders and web-server flaws FT13. Firewalls of the day either ran as software on general-purpose servers, as Check Point's FireWall-1 did on Sun and HP machines or in Nokia appliances FT22, or came as small dedicated boxes with firewall and VPN for small businesses FT21; custom-chip appliances had pushed firewall speed to a gigabit, but only for network-layer work FT14. Antivirus, intrusion detection and web filtering were separate products, each another box or server to buy, configure and update, a load that small firms without security staff struggled to carry FT15 FT1. Scanning content takes much more processing than passing packets, so adding it on ordinary processors slowed the connection FT15 FT24.
What shaped the outcome
Step 1 of 4 · 2000–09
A NetScreen founder put virus scanning on custom chips and led the fast end of a new category
Ken Xie had sold software firewalls at his first company and concluded that a firewall on a PC operating system was not reliable enough; at NetScreen, which he co-founded in 1997, firewall and VPN work ran on custom chips in a dedicated box, and NetScreen built the first gigabit firewall FT2 FT14. He says NetScreen did not want to go beyond the firewall, so in October 2000 he and his brother Michael started again with about a dozen engineers, aiming at integrated network and content security 'without crippling network performance' FT2 FT4. The first FortiGate shipped in May 2002 as an antivirus firewall: its FortiASIC chip ran virus scanning, intrusion detection and encryption beside general-purpose processors, and ICSA Labs certified its gateway antivirus that August, the first ASIC-based gateway to pass FT4 FT30 FT29. The six-model line scaled from small offices to service providers; by 2003 a FortiGate-50 cost about 500 pounds, a FortiGate-400 about 6,000 pounds and a carrier-class FortiGate-3000 about $20,000 FT29 FT33 FT30. The first named buyers wanted speed. In February 2003 KDDI chose FortiGate for its managed antivirus service across its DSL lines because it scanned at a pace comparable to the line, and the German distributor eSeSIX signed on for 'high speed, network-based antivirus gateways, at exceptional price-per-performance' FT38 FT39. In 2006 IDC analyst Charles Kolodgy, who coined the name unified threat management, placed Fortinet first at the high end of the category and SonicWall first at the low end; only Fortinet and ISS had passed NSS Group's UTM test FT37. In a Network World lab test in 2007 the FortiGate-3610A scanned for viruses at 524 Mbps; none of the other gigabit firewalls passed 300 Mbps with antivirus on, and it alone ran firewall, antivirus and intrusion prevention together at 520 Mbps FT31. By early 2009 IDC ranked Fortinet first in the whole category with 13.9% share FT1.
Scanning content takes far more computing than forwarding packets; Xie later put the gap at 50 to 100 times FT24. A vendor running antivirus on general-purpose processors lost throughput as soon as the scanner was switched on, and carriers and large sites with the fastest links felt that loss most. Fortinet's chip let one box carry the content work at those speeds, and the same design came down to a branch box, so one line served both ends. Joel Snyder drew the conclusion for enterprise buyers in 2007: antivirus on a UTM was impractical at gigabit speeds except on the FortiGate FT31. Xie's NetScreen years supplied both the chip method and the conviction that the firewall alone was no longer the job FT2.
Rivals SonicWall, the low-end leader, sold firewall and VPN appliances to small businesses and licensed its antivirus from McAfee; Cisco and Secure Computing licensed Trend Micro, while Fortinet kept its own signature database FT21 FT37 FT30. NSS Group's Bob Walder said in 2006 that SonicWall 'simply does not have the horsepower' for antispam on a UTM FT37. SonicWall's 2009 answer, a multi-core E-Class line, rated its top boxes at 850 Mbps to 1.7 Gbps with security services on, against 3.9 to 5.6 Gbps as plain firewalls FT43. Check Point sourced antivirus from third parties and WatchGuard kept generic processors FT15. Every vendor, Fortinet included, conceded a throughput cost with all services running; Fortinet's marketing chief put it at up to half FT37.

Distributors in three regions carried it from the first year
Xie launched the first product in the Americas, Europe and Asia at once, unlike the usual US-first start FT2. By February 2003 Fortinet had offices in the UK and France and signed German distributor eSeSIX, whose founder said customers were 'longing for a cost-effective integrated security platform' FT39. Exclusive Networks began distributing FortiGate in France in 2003 and was its sole distributor there for many years; its founder Olivier Breittmayer committed the young distributor to the line FT36. A channel program followed in October 2003, with Canadian and UK distribution in the next months FTX1. From 2004 Fortinet licensed every security function per box rather than per user FT40. By June 2009 substantially all revenue came through distributors and resellers: more than 5,000 partners had taken 450,000 appliances to 75,000 end customers, partners had no minimum purchases, and Fortinet's own salespeople worked alongside resellers on larger deals FT1. Europe, the Middle East and Africa supplied 38% of revenue and Asia 26% FT1. Exclusive Networks grew to 18% of revenue by 2015 FT7. In 2025 sales still ran through a two-tier model, with six distributors holding 67% of receivables FT6.
A line sold from a branch office up to a carrier could not carry a direct sales call at the low end. Distributors and resellers who already looked after those buyers could add a FortiGate and its yearly renewal to each account, with no minimums and no per-user counting to slow a quote. Launching in all regions at once put the product in front of European and Asian partners early, and by 2009 most revenue came from outside the Americas FT1.
Rivals SonicWall's channel was wider: more than 15,000 resellers and 300,000 active customers by 2012, yet its trailing revenue was about $260 million when Dell bought it, against Fortinet's $434 million in 2011 FT42 FT26. Check Point sold its software on partners' hardware FT22. Partners therefore did not separate Fortinet from its rivals by themselves; they carried the product difference in the first argument to buyers in three regions.

Owning the chip, the operating system and the threat research spread costs over the most firewall units
Fortinet designs its own security processors and has them made at TSMC and other foundries; content, network and system-on-chip lines followed, each sold across the product range FT1 FT7. It writes its own operating system and runs its own threat research team, which feeds the FortiGuard subscriptions on every box FT1. Xie says 'we are probably the only company' in network security developing an ASIC, 'which needs a very big, long-term investment', and prefers to grow by innovation 'instead of based on acquisitions' FT9. His marketing chief, John Maddison, says 'we can forward-order millions versus tens of thousands' of chips for price leverage, and that one system-on-chip replaces parts others source separately FT3. In 2023 Fortinet claimed its SP5 gave 17 to 32 times the throughput of similarly priced rivals on general-purpose processors, with 88% less power FT16 FT19. Maddison puts the rise in shipment share at about 10% to almost 50% FT3. Fortinet, reporting IDC's tracker, gave its 2021 share of firewall, UTM and VPN units as 36.8%, the most appliances shipped for nine straight years FT35; by revenue IDC put it level with Palo Alto Networks in mid-2023, at 21.3% against 21.0% FT34. Subscriptions and support grew to more than half of revenue by 2009 FT1.
Chip design is a large fixed cost; spread over more units than any rival ships, it lowers the cost of each unit of protected throughput, and the volume itself improves supply terms. The company's own claims put the result in price-performance and power use, which lets resellers quote a cheaper box for the same traffic. Rivals that buy merchant processors avoid the design cost but pay more per unit of throughput, and a rival starting a chip program now would fund it across a fraction of Fortinet's volume. The Antifragile Investor reads the same combination of chips, platform and subscriptions as the core of Fortinet's advantage FTX3.
Rivals Palo Alto Networks, founded in 2005, built a higher-priced enterprise platform with a la carte subscriptions and grew it by acquisition, reaching a $200 billion market value in May 2026 FT20 FT28. Fortinet's comparison page answers it on throughput per dollar and watts per gigabit FT28. Winning on units did not make Fortinet the more valuable company, and on revenue the two were level in 2023 FT34. Most other UTM makers had moved to Intel's general-purpose server processors by 2007; Joel Snyder found Fortinet and Juniper among the few still shipping heavily engineered custom hardware FT32.

Installed FortiGates took on SD-WAN and fabric duties by software update
From 2015 Fortinet spent to win larger enterprise accounts FT7. In April 2016 it launched the Security Fabric, linking FortiGate, its other products and third-party tools through FortiOS; Xie contrasted it with 'platforms loosely coupled at the management level' FT8. In October 2018 it built SD-WAN into FortiOS on every FortiGate at no extra licence, so about three million installed devices could gain it by software update FT11. Within a year it held 11% of SD-WAN, third in Gartner's count, and closed eight SD-WAN deals over $1 million in a quarter against one a year earlier FT10. Dell'Oro counted Fortinet's branch revenue (access routers, SD-WAN and low-end firewalls) rising from $345 million to $919 million over the five years to 2024, against Cisco's flat $2.6 billion and Palo Alto Networks' $625 million, and noted that Fortinet sells one hardware family on one operating system FT41. Gartner named it a Leader in SD-WAN five years running, and it reported more than 40,000 SD-WAN customers FT27; SD-WAN and operational-technology security reached over a quarter of bookings in 2023 FT16 FT23. Revenue rose from $1.01 billion in 2015 to $6.80 billion in 2025, and 80% of the Fortune 100 were customers by 2024 FT7 FT6 FT18. Growth slowed to 12% in 2024 and reached 26% in the quarter to June 2026, after the company had forecast a firewall refresh cycle FT26 FT6.
Because every FortiGate already sat at the edge of a branch network running the same operating system, a branch-networking function could reach existing customers as a software release, and the custom chips had headroom to run it alongside security. Branch networking has traditionally been bought from networking vendors; bundling it into the firewall gave Fortinet a reason to be in enterprise WAN deals it had not been part of.
Fortinet also bought capabilities to broaden the Security Fabric. It completed the Lacework acquisition in August 2024, adding a cloud-native application protection platform and its engineering and sales teams FTMA-1. The Next DLP purchase closed that same month, adding data protection technology for standalone enterprise sales and planned integration into Fortinet's SASE offering FTMA-2. These purchases extended the portfolio into cloud security and data protection FT18.
Rivals Enterprises could buy SD-WAN from networking specialists such as Cisco and keep a separate firewall; Dell'Oro counted Cisco's branch revenue flat at about $2.6 billion over the same five years FT41. Palo Alto Networks reached the branch through a second hardware line from its CloudGenix purchase and grew faster from a smaller base, to $625 million FT41, and bought its way into other adjacent products, completing a $25 billion CyberArk purchase in 2026 FT20. Fortinet went from essentially no SD-WAN share to 11% in a year with no new hardware for existing customers FT10 FT11.
