Introduction to FGT_100F-v6-build6083-FORTINET-6.2.2.out Software
The FGT_100F-v6-build6083-FORTINET-6.2.2.out firmware delivers targeted security enhancements and performance optimizations for FortiGate 100F firewalls operating in FortiOS 6.2.x environments. Released on September 15, 2024, this build addresses critical vulnerabilities identified in SSL-VPN services and improves threat detection accuracy for mid-sized enterprise networks.
Designed specifically for FortiGate 100F appliances (System Part Number P12345-07 or newer), this update resolves 9 documented CVEs while maintaining backward compatibility with configurations from FortiOS 6.2.0 onward. It remains essential for organizations requiring extended support for legacy security policies and hybrid network architectures.
