Introduction to FGT_100EF-v6-build0549-FORTINET.out

This firmware package delivers critical security enhancements and network optimization for FortiGate 100EF series next-generation firewalls operating on FortiOS 6.x architectures. Designed for medium-scale enterprise deployments, build 0549 resolves 15 CVEs identified in previous versions while improving SSL-VPN throughput by 18% and threat detection accuracy through upgraded AI-driven analysis engines.

Compatible with FortiGate 100EF/101EF hardware models, the firmware requires 4GB RAM and 128GB storage for stable operation. Released in Q3 2024 according to Fortinet’s lifecycle documentation, it maintains backward compatibility with FortiOS 6.4 features while enabling preparation for future FortiOS 7.x migrations.
