Introduction to FGT_3401E-v7.2.0.F-build1157-FORTINET.out
This enterprise-grade firmware package delivers foundational security updates and operational enhancements for FortiGate 3401E hyperscale firewalls, designed for mission-critical network protection in large enterprise and service provider environments. Released under FortiOS 7.2.0 framework (Build 1157), it addresses critical vulnerabilities disclosed in Q4 2024, including SSL-VPN session fixation risks and IPSec protocol stack weaknesses.
Exclusive to FortiGate 3401E hardware, this update ensures backward compatibility with configurations from FortiOS 7.0.x onward while introducing quantum-resistant encryption standards. Based on Fortinet’s Q4 2024 security advisory cycle, the firmware optimizes threat detection through upgraded FortiGuard AI engines and introduces hardware-accelerated TLS 1.3 decryption for 400 Gbps firewall throughput.
