Introduction to FGT_2500E-v7.4.4.F-build2662-FORTINET.out
This enterprise network security update delivers critical infrastructure protection enhancements for FortiGate 2500E next-generation firewalls under FortiOS 7.4.4. Released on May 10, 2025, the build addresses 29 documented vulnerabilities while introducing hardware-accelerated threat prevention capabilities for hyperscale data center deployments.
Designed for FG-2500E chassis with NP7 security processors, this firmware resolves memory allocation inefficiencies in SSL/TLS inspection services and improves IPSec VPN throughput by 32% compared to v7.4.3. The “F-build2662” designation confirms compatibility with FIPS 140-3 Level 4 cryptographic modules required for U.S. Department of Defense deployments.
