Introduction to FGT_100F-v7.4.1.F-build2463-FORTINET.out.zip
This enterprise security firmware delivers FortiOS 7.4.1.F for FortiGate 100F series appliances, designed to address advanced network protection requirements in distributed branch office environments. Released under Fortinet’s Q2 2025 security update cycle (build 2463), this version combines hardware-accelerated threat prevention with enhanced operational visibility for hybrid network architectures.
Specifically optimized for the 100F hardware platform’s Security Processor 4 (SP4) architecture, the firmware improves encrypted traffic inspection efficiency while maintaining backward compatibility with SD-WAN configurations. Network administrators managing retail and remote office deployments will benefit from its upgraded SSL-VPN stability and refined application control mechanisms.
