Introduction to FGT_2601F-v7.2.8.M-build1639-FORTINET.out

This firmware release (build 1639) represents Fortinet’s latest maintenance update for the FortiGate 2601F next-generation firewall under FortiOS 7.2.8.M branch. Designed for enterprise-grade network security infrastructure, it delivers critical security hardening and operational stability enhancements while maintaining backward compatibility with existing 7.2.x configurations.

Targeting high-throughput environments such as data centers and telecom edge networks, this build focuses on optimizing FortiASIC-accelerated threat prevention for networks requiring uninterrupted uptime. The “M” designation confirms its role as a long-term support release with security patches backported from FortiOS 7.4.x versions.
