Introduction to FGT_101F-v7.2.1.F-build1254-FORTINET.out
This firmware marks the inaugural Feature Release (FR) of FortiOS 7.2.x for FortiGate 101F next-generation firewalls, designed to deliver enterprise-grade security for distributed branch offices. Released on May 10, 2025 (build 1254), it introduces architectural improvements optimized for SD-WAN deployments requiring <15ms latency thresholds.
The “.F” designation confirms this as a full-feature update requiring fresh installation for systems upgrading from FortiOS 6.4.x. Exclusively compatible with the 101F hardware platform (FG-101F), it supports up to 5,000 concurrent VPN tunnels and 8Gbps threat inspection throughput – a 30% improvement over previous 7.0.x releases.
