Introduction to FGT_501E-v6-build0365-FORTINET.out.zip Software

This firmware package provides critical security enhancements for Fortinet’s FortiGate 501E next-generation firewall platform, addressing vulnerabilities in FortiOS 6.0.x branch. Released under Fortinet’s Extended Support Lifecycle program in Q3 2024, build0365 resolves 7 CVEs rated high/critical severity while maintaining backward compatibility with existing network configurations.

Designed for medium-sized enterprise networks, this v6.0.7 update extends hardware lifecycle support for FortiGate 501E devices deployed in distributed environments. It bridges security gaps between legacy FortiOS 6.x and modern 7.x architectures, enabling organizations to maintain NIST 800-53 compliance without infrastructure upgrades.
