​​Introduction to FGT_71F-v7.4.4.F-build2662-FORTINET.out.zip​​

The ​​FGT_71F-v7.4.4.F-build2662-FORTINET.out.zip​​ firmware package delivers critical updates for Fortinet’s FortiGate 71F series, a compact next-generation firewall (NGFW) optimized for small-to-medium enterprises and branch offices. Released under FortiOS 7.4.4 in Q2 2025, this build addresses 14 security vulnerabilities while introducing hardware-accelerated threat prevention for modern network environments.

Designed exclusively for the FortiGate 71F hardware platform (FG-71F), this firmware enhances operational efficiency through improved SSL inspection performance and expanded IoT device identification capabilities. It maintains backward compatibility with SD-WAN configurations deployed since FortiOS 7.2.
