Introduction to FGT_91E-v7.4.4.F-build2662-FORTINET.out
This firmware delivers FortiOS 7.4.4 for FortiGate 90E series firewalls, targeting mid-sized enterprises requiring advanced threat protection with energy-efficient performance. Officially released in Q1 2025, build 2662 resolves 14 security vulnerabilities while introducing hardware-accelerated Zero Trust Network Access (ZTNA) and 25 Gbps threat inspection capabilities. Designed for hybrid work environments, it supports 4,000 concurrent VPN connections and reduces power consumption by 38% compared to previous versions.
Exclusive to FortiGate 91E hardware, this update strengthens compliance with NIST CSF 2.0 and ISO 27001 frameworks through enhanced logging granularity.
