Introduction to FGT_101F-v6.M-build2095-FORTINET.out Software

This firmware release provides critical security enhancements and performance optimizations for Fortinet’s FortiGate 101F next-generation firewall. Designed for enterprise network environments, build 2095 addresses 12 CVEs identified in FortiOS 6.4 branch while introducing hardware-specific optimizations for the FG-101F’s NP6 network processor.

Compatible exclusively with FortiGate 101F hardware (FG-101F model series), this firmware maintains backward compatibility with configurations from FortiOS 6.4.1 through 6.4.12. The release became available through Fortinet’s support portal on 14 May 2025, following extended stability testing across 150+ enterprise deployment scenarios.
