1. Introduction to FGT_4401F-v6.M-build2030-FORTINET.out

This critical firmware update targets Fortinet’s FortiGate 4401F next-generation firewall platform, designed for high-performance enterprise network security operations. As part of FortiOS 6.4 Maintenance Release updates, build2030 addresses 9 CVEs while introducing hardware-specific optimizations for 4000-series appliances.

Compatible exclusively with FortiGate 4401F hardware running FortiOS 6.4.x, this Q3 2024 release extends lifecycle support through 2026. The firmware maintains backward compatibility with configurations created in FortiOS 6.2.9+ while introducing enhanced Security Fabric integrations.
