​​Introduction to FGT_1001F-v7.4.4.F-build2662-FORTINET.out.zip​​

This firmware package delivers FortiOS 7.4.4.F for FortiGate 1000F series next-generation firewalls, addressing critical vulnerabilities disclosed in Fortinet’s Q2 2025 security advisories. Released on May 10, 2025, Build 2662 specifically targets persistent threats exploiting SSL-VPN weaknesses and implements enhanced protections against advanced attack vectors observed in global network environments.

Designed for high-availability network architectures, the 1000F series (including FG-1001F models) leverages this update to strengthen Security Fabric integration while maintaining 200Gbps+ threat protection throughput. The firmware aligns with Fortinet’s Zero Trust 2.1 framework, enabling granular application access controls across hybrid cloud deployments.
