Introduction to FGT_4400F-v7.2.4.F-build1396-FORTINET.out

This firmware package delivers FortiOS 7.2.4 Feature Release (build 1396) for the FortiGate 4400F hyperscale firewall platform. Designed for enterprise and service provider networks requiring multi-100Gbps throughput, this update integrates critical security patches disclosed in Fortinet’s Q1 2025 Security Advisory.

Compatible with all 4400F hardware revisions (manufactured 2023 onward), the firmware introduces zero-trust workload protection for hybrid cloud environments. Release notes confirm backward compatibility with configurations from FortiOS 7.0.x through automated policy migration tools.

Key Features and Improvements
