1. Introduction to FGT_600E-v7.0.3-build0237-FORTINET.out

This firmware update delivers FortiOS 7.0.3 for FortiGate 600E series next-generation firewalls, specifically optimized for mid-sized enterprises requiring enhanced SD-WAN and zero-trust capabilities. The build (0237) addresses 9 critical CVEs identified in FortiOS 7.0.x branch while introducing hardware-accelerated TLS 1.3 decryption for improved security inspection throughput.

Compatible exclusively with 600E/620E/640E hardware variants, this release supports hybrid mesh firewall configurations and provides backward compatibility with FortiManager 7.4.2+ centralized management systems. The firmware was officially released on March 15, 2025, with extended security patching commitment until Q3 2028.
