Introduction to FGT_101F-v7.2.6.F-build1575-FORTINET.out
This firmware package delivers FortiOS 7.2.6 Feature Release (build 1575) for the FortiGate 101F series, designed for branch office networks requiring enterprise-grade security in compact form factors. Released under Fortinet’s Q2 2025 security maintenance cycle, it addresses 12 CVEs disclosed in FG-IR-25-105 advisory while enhancing IoT device protection capabilities.
Compatible with 101F hardware revisions manufactured since 2023, the update introduces hardware-accelerated ZTNA 2.2 protocols and expands Microsoft Entra ID integration. The firmware maintains backward compatibility with configurations from FortiOS 7.0.x through automated policy migration tools, specifically optimized for SD-WAN deployments under 1Gbps throughput requirements.
