Introduction to FGT_80F-v7.2.7.M-build1577-FORTINET.out

This firmware package delivers critical security patches and performance optimizations for FortiGate 80F next-generation firewalls, aligning with FortiOS 7.2.7 standards. Released on March 18, 2025, it addresses 7 documented vulnerabilities while improving SSL inspection throughput by 22% compared to build 1563. Designed for mid-sized enterprise networks, the update supports 80F series appliances requiring enhanced threat detection capabilities with minimal downtime.

Compatible with FortiGate 80F/81F hardware variants, this build requires FortiOS 7.2.4 or newer. Release notes confirm compatibility with SD-WAN architectures using 1GbE/10GbE interfaces.
