Introduction to FGT_1801F-v6-build6931-FORTINET.out

This firmware release (FGT_1801F-v6-build6931-FORTINET.out) delivers enterprise-grade security enhancements and hardware optimizations for Fortinet’s FortiGate 1801F hyperscale firewall platform. Designed for data centers and large enterprise networks, this Q1 2025 update addresses 18 CVEs identified in FortiOS 6.4.x while optimizing NP7 security processor cluster performance.

Specifically engineered for FortiGate 1801F hardware running FortiOS v6.4.12+, the build resolves critical vulnerabilities in SSL/TLS inspection modules and improves threat prevention throughput by 28% through ASIC-accelerated pattern matching. The update aligns with Fortinet’s Q4 2024 security advisory addressing session hijacking risks in high-density network environments.
