Introduction to FGT_400E_BP-v7.2.2.F-build1255-FORTINET.out

This firmware release (build 1255) delivers critical security updates and hardware-specific optimizations for FortiGate 400E_BP series appliances under FortiOS 7.2.2. Designed for enterprise branch offices requiring carrier-grade network protection, it addresses 19 CVEs identified in Fortinet’s Q1 2025 security advisories while enhancing performance for high-density environments.

Specifically engineered for FortiGate 400E_BP (FG-400E_BP) hardware, the firmware requires 32GB RAM and 480GB SSD storage. Released on February 18, 2025, it replaces the deprecated 7.2.1 branch with extended technical support through Q4 2027.
