1. Introduction to FGT_500E-v6-build1263-FORTINET.out

This firmware release delivers critical security patches and performance optimizations for FortiGate 500E series next-generation firewalls, designed for medium-to-large enterprises requiring robust network protection. As part of FortiOS 6.2 architecture, it addresses 14 CVEs identified in Fortinet’s Q3 2024 security advisories while maintaining backward compatibility with existing SD-WAN and VPN configurations.

Optimized for high-density network environments, this build supports hardware-accelerated threat inspection up to 180 Gbps firewall throughput. Exclusively compatible with FortiGate 500E hardware variants (FG-500E, FG-500E-SXM), it requires minimum 16GB RAM and FortiOS 6.0.4+ baseline installations for deployment.
