​​Introduction to FGT_800D-v6-build1392-FORTINET.out Software​​

This firmware update delivers critical security patches and operational optimizations for Fortinet’s FortiGate 800D series, a mid-range enterprise firewall designed for high-availability network architectures. Released on November 4, 2024, as part of FortiOS 6.4.12’s lifecycle updates, build1392 resolves 9 documented vulnerabilities while improving threat inspection throughput by 18% compared to previous 6.4.x versions.

Exclusively compatible with FortiGate 800D hardware (FG-800D/FG-801D), this firmware supports configurations from FortiOS 6.4.5 onward. It addresses critical CVEs disclosed in Fortinet’s Q4 2024 security advisories while enhancing SD-WAN performance for distributed enterprise networks.
