Introduction to FGT_500E-v6-build0200-FORTINET.out.zip

This firmware package delivers critical security updates and operational optimizations for Fortinet’s FortiGate 500E next-generation firewall platform. Released under FortiOS 6.4.4 (build 0200), it addresses 7 CVEs rated high/critical severity while enhancing network performance for medium-to-large enterprise deployments. The update became generally available in Q3 2024 through Fortinet’s support portal for registered customers.

Designed exclusively for the FortiGate 500E hardware platform (FG-500E), this firmware requires minimum hardware revision B+ and FortiManager 6.4.5+ for centralized policy management. It maintains backward compatibility with FortiOS 6.2 configurations but mandates 8GB RAM and 64GB SSD storage for optimal operation.
