Introduction to FGT_81F-v7.0.10.M-build0450-FORTINET.out
This firmware update delivers critical security hardening for FortiGate 81F series next-generation firewalls, optimized for mid-sized enterprise networks requiring advanced threat prevention. Released on May 10, 2025, it resolves 5 CVEs disclosed in Q1 2025 while improving SSL inspection throughput by 18% compared to v7.0.9 builds.
Designed specifically for FortiGate 81F appliances with NP6XLite security processors, this release introduces hardware-accelerated TLS 1.3 decryption and complies with FIPS 140-3 Level 2 standards. Backward compatibility extends to configurations from FortiOS 7.0.x, but requires hardware revision B3+ for full functionality.
