Introduction to FGT_3401E-v7.2.5.F-build1517-FORTINET.out.zip

This critical firmware update addresses authentication bypass vulnerabilities in FortiGate 3401E hyperscale firewalls under FortiOS 7.2.5.F Feature Release. Designed for enterprises requiring 200Gbps+ threat prevention throughput, build 1517 introduces hardware-accelerated quantum-safe VPN prototypes while maintaining backward compatibility with existing SD-WAN configurations.

Validated for FG-3401E hardware models (FGT-3401E and FGT-3401E-POE), this January 2025 release targets organizations operating in regulated industries requiring FIPS 140-3 compliance. The “F” designation confirms its validation for networks prioritizing zero-trust architecture implementations with minimal downtime.
