Introduction to FGT_100F-v7.4.1.F-build2463-FORTINET.out

This firmware package delivers FortiOS 7.4.1 for FortiGate 100F next-generation firewalls, designed for mid-sized enterprises requiring advanced threat protection with hardware-accelerated security processing. Released in March 2025 as part of Fortinet’s quarterly security update cycle, build 2463 resolves 14 critical vulnerabilities while introducing enhanced protocol support for modern network architectures.

The software targets FortiGate 100F appliances equipped with SP5 security processors, supporting up to 10 Gbps threat inspection throughput. It maintains backward compatibility with FortiOS 7.2.x configurations but requires FortiManager 7.4.1+ for complete Security Fabric integration.
