​Introduction to FGT_401E-v6-build1914-FORTINET.out Software​

The ​​FGT_401E-v6-build1914-FORTINET.out​​ firmware package delivers essential security updates and operational enhancements for FortiGate 401E next-generation firewalls running FortiOS 6.4.11. Released under Fortinet’s Q1 2025 Security Advisory Cycle (FG-IR-25-115), this build addresses 9 documented CVEs while improving threat prevention throughput by 19% compared to previous versions.

Designed for mid-sized enterprise networks, this firmware supports FortiGate 401E appliances with dual NP6 security processors. Key applications include 10Gbps SSL inspection, automated attack surface reduction, and zero-trust network access (ZTNA) enforcement for hybrid workforce environments. Compatible devices include FortiGate 401E and 400E models with minimum FortiOS 6.4.8 installations.


​Key Features and Improvements​
