1. Introduction to FGT_100F-v7.2.5.F-build1517-FORTINET.out

This firmware release delivers FortiOS 7.2.5.F for the FortiGate 100F series, a mid-range next-generation firewall designed for enterprise branch offices and distributed networks. Officially released in Q2 2025 under Fortinet’s Feature Release (F-build) track, it combines 14 security vulnerability patches with hardware-specific optimizations for the 100F’s NP6 security processing unit.

The 7.2.5.F-build1517 version introduces enhanced threat intelligence sharing capabilities with FortiAnalyzer 7.6.3+ while maintaining backward compatibility with SD-WAN configurations from FortiOS 7.0.x deployments. It specifically addresses performance bottlenecks observed in high-density VPN environments with 500+ concurrent connections.
