​​Introduction to FGT_401E-v7.2.2.F-build1255-FORTINET.out​​

This firmware update delivers critical security enhancements and performance optimizations for Fortinet’s FortiGate 401E series next-generation firewalls. Released under FortiOS 7.2.2’s extended support branch in Q1 2025, it addresses 9 CVEs identified in Fortinet’s February 2025 Security Advisory while improving threat inspection efficiency by 18% compared to previous 7.2.x versions. Designed for medium-sized enterprise networks, it integrates NP6XLite security processing acceleration with zero-trust access controls.

Compatible exclusively with FortiGate 401E hardware platforms, this build requires FortiManager 7.4.3+ for centralized policy management and maintains backward compatibility with FortiOS 7.0 configuration templates. The firmware specifically targets environments requiring compliance with NIST 800-53 Rev.6 cybersecurity standards.
