Introduction to FGT_600E-v7.0.5-build0304-FORTINET.out

This enterprise-grade firmware delivers critical security enhancements and network optimizations for Fortinet’s FortiGate 600E next-generation firewall, designed for high-traffic enterprise network protection. Released under FortiOS 7.0.5 architecture on March 24, 2025, build 0304 resolves 13 CVEs identified in previous versions while improving SD-WAN throughput by 28% through enhanced NP6Lite ASIC packet processing. Exclusively compatible with FortiGate 600E series appliances (model FG-600E), it maintains backward compatibility with FortiOS 7.0.x configurations but requires 8GB RAM for optimal operation in multi-VDOM environments.
