Fortinet, Inc.

Service revenue at approximately 67% of FY2025 total ($4.58B of $6.8B), backed by deferred revenue of $6.36B at year-end 2024 across 750,000+ customer installations. High renewal rates and multi-year support contracts provide solid forward visibility, though the hardware product segment (~33% of total) introduces cyclical lumpiness, as demonstrated in FY2023.

Fortinet sells across network firewalls, SASE, SD-WAN, OT security, and SecOps, with SASE billings growing 40% in Q4 2025 and OT security billings up more than 25% in FY2025. All product lines operate within the cybersecurity domain and are sold through a unified Security Fabric, providing portfolio breadth within a single end market rather than uncorrelated diversification.

FY2024 revenue was distributed across Americas ($2.44B, 41%), EMEA ($2.40B, 40%), and APAC ($1.12B, 19%), with EMEA growing fastest at 18% in FY2025. The Americas/EMEA split is unusually balanced for a US-headquartered technology company, and no single region dominates. APAC at roughly 19% is meaningful but lighter.

Non-GAAP operating margins expanded from roughly 27% in FY2021 to above 35% by FY2024, driven by FortiOS platform economics and the fixed-cost nature of ASIC-based infrastructure. FCF held at $1.73B in FY2023 during the hardware trough and rose to $2.2B by FY2025, confirming durable operating leverage across the cycle even as product revenue was pressured.

Security subscriptions and support services ($4.58B in FY2025) are mission-critical and contractual, with multi-year commitments reflected in the $6.36B deferred revenue base at end-2024. Firewall and security infrastructure is non-discretionary for enterprise and government operations, though approximately one-third of revenue from hardware appliances remains transactional and cycle-sensitive.
