Introduction to FGT_4200F-v7.4.4.F-build2662-FORTINET.out

This firmware update targets Fortinet’s high-performance ​​FortiGate 4200F​​ hyperscale firewall series, delivering critical stability enhancements and security patches under FortiOS 7.4.4. Officially released in June 2025, the build focuses on optimizing threat prevention throughput for enterprises managing 100+ Gbps encrypted traffic. Designed exclusively for the 4200F hardware platform (FG-4200F/FG-4200F-ES), it maintains backward compatibility with configurations from FortiOS 7.4.1 onward while introducing hardware-specific optimizations for SPU (Security Processing Unit) utilization.
