Introduction to FGT_100E-v6-build1392-FORTINET.out Software
This firmware package delivers critical security updates and operational optimizations for Fortinet’s FortiGate 100E series next-generation firewalls, designed for mid-sized enterprise networks. Released on March 15, 2024, as part of FortiOS 6.4.10’s lifecycle updates, build1392 resolves 11 CVEs while improving threat detection accuracy by 19% compared to prior 6.4.x releases.
Exclusively compatible with FortiGate 100E hardware models (FG-100E/FG-101E), this version maintains backward compatibility with configurations from FortiOS 6.4.5 through 6.4.9. It addresses critical vulnerabilities disclosed in Fortinet’s Q1 2024 security advisories while enhancing SD-WAN performance for hybrid network environments.
