1. Introduction to FGT_601E-v7.2.4.F-build1396-FORTINET.out
This firmware update targets Fortinet’s FortiGate 601E series, a high-performance next-generation firewall platform designed for enterprise networks requiring 20 Gbps+ threat protection throughput. The build integrates FortiOS 7.2.4 feature enhancements with hardware-specific optimizations for the 601E’s NP7 network processors and security processing units (SPUs).
As part of Fortinet’s quarterly maintenance cycle, this release prioritizes stability improvements for hyperscale VPN deployments and resolves critical vulnerabilities reported in Q1 2025. While not explicitly listed in public release notes, the version identifier aligns with FortiOS 7.2.4 branch updates focused on SD-WAN performance tuning and Zero Trust Network Access (ZTNA) protocol upgrades.
