​​Introduction to FGT_500D-v6-build1319-FORTINET.out.zip Software​​

This firmware package delivers critical security updates for FortiGate 500D firewalls operating on FortiOS 6.2, specifically designed for enterprises maintaining legacy infrastructure during phased IT modernization. Released under Fortinet’s Extended Security Maintenance (ESM) program in Q3 2024, this build addresses 14 CVEs while preserving backward compatibility with hybrid network environments.

Targeting the FG-500D hardware platform, this update supports organizations requiring extended lifecycle support for high-performance network security appliances. The firmware maintains compatibility with FortiManager 6.4.x centralized management systems while implementing SHA-3 certificate validation frameworks.
