Introduction to FGT_601E-v6-build0549-FORTINET.out

This firmware package delivers critical security updates and network performance enhancements for FortiGate 601E series next-generation firewalls operating on FortiOS 6.x architectures. Designed for high-throughput enterprise environments, build 0549 resolves 14 CVEs identified in legacy versions while improving SSL-VPN stability and threat detection efficiency through advanced AI-driven analysis.

Compatible with FortiGate 601E/602E hardware models, the firmware requires 8GB RAM and 512GB storage for optimal operation. Released in Q2 2025 according to Fortinet’s lifecycle documentation, it maintains backward compatibility with FortiOS 6.4 features while preparing systems for future FortiOS 7.x migrations.
