Direct Answer
Fortinet reports revenue across 3 product and service lines in its fiscal 2025 Form 10-K. Security Subscription is the largest, with $2.6 billion of revenue (39% of the total), followed by Product at $2.2 billion (33%). 28% of revenue came from the United States.
How Does Fortinet Make Money?
No single line supplies a majority of revenue: the largest, Security Subscription, is 39%, which spreads Fortinet's exposure across several demand drivers. Between fiscal 2024 and 2025, Product grew fastest (+16.2%) and Technical Support and Other slowest (+12.6%), so the revenue mix tilts toward Product while that gap lasts.
| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Security Subscription | $2.6 billion | $2.3 billion | 38.7% | 13.7% |
| Product | $2.2 billion | $1.9 billion | 32.6% | 16.2% |
| Technical Support and Other | $1.9 billion | $1.7 billion | 28.6% | 12.6% |
Where Does Fortinet's Revenue Come From?
Regions follow the definitions in the filing; most companies assign revenue by customer location.
| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Europe Middle East and Africa | $2.8 billion | $2.4 billion | 41.7% | 18.3% |

What the Segment Figures Do Not Show
The rows above add up to 100% of Fortinet's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Fortinet reported in the segment note and revenue disclosures of its Form 10-K filed February 25, 2026 (accession 0001262039-26-000007), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
