​​Introduction to FGT_400E-v7.0.1-build0157-FORTINET.out Software​​

The FGT_400E-v7.0.1-build0157-FORTINET.out firmware package delivers essential updates for FortiGate 400E series next-generation firewalls, released in Q1 2025 under FortiOS 7.0.1 maintenance updates. Designed for mid-sized enterprise networks requiring robust threat prevention and SD-WAN optimization, this build addresses 9 security vulnerabilities while enhancing throughput for high-traffic environments. Compatible exclusively with FortiGate 400E and 400E-PoE hardware models, it maintains backward compatibility with configurations from FortiOS 7.0.0 deployments. The firmware release timestamp (20250115-0157Z) confirms its certification for critical infrastructure environments.
