Introduction to FGT_2601F-v7.4.4.F-build2662-FORTINET.out.zip

This firmware package delivers enterprise-grade security hardening and performance optimization for FortiGate 2601F hyperscale firewalls running FortiOS 7.4.4. Officially released through Fortinet’s Q3 2025 security advisories, build2662 addresses 11 critical CVEs while achieving 320Gbps threat inspection throughput – a 22% improvement over previous versions. Designed for carrier-grade network environments, it combines quantum-safe encryption with NP7 processor optimizations for 5G core network protection.

The firmware maintains backward compatibility with configurations from FortiOS 7.2.7+ and requires 32GB flash storage. Network architects managing multi-terabit infrastructures should prioritize installation due to its sub-microsecond latency improvements for financial trading systems and IoT device management platforms.
