Introduction to FGT_400F-v7.4.4.F-build2662-FORTINET.out.zip

This firmware package delivers FortiOS 7.4.4 for FortiGate 400F series next-generation firewalls, engineered to address enterprise-grade security requirements while optimizing network performance. As part of Fortinet’s Feature Release (F-build) cycle, this version introduces 22+ functional enhancements validated through 90-day lab testing protocols.

Specifically designed for the 400F hardware platform (FG-400F, FG-400F-POE), the firmware supports 45Gbps threat protection throughput with full UTM/IPS inspection capabilities. The “F-build2662” designation confirms compatibility with SOC4+ security processors and NP7 network acceleration ASICs, making it suitable for high-density data center deployments.
