Introduction to FGT_90E-v7.4.1.F-build2463-FORTINET.out Software

This firmware delivers FortiOS 7.4.1 for FortiGate 90E series next-generation firewalls, targeting critical security hardening and operational stability improvements for enterprise networks. Released in Q2 2025 under extended vendor support, build 2463 resolves 3 high-risk CVEs identified in previous 7.4.x releases while maintaining backward compatibility with configurations from FortiOS 7.2.

Designed specifically for the 90E hardware platform’s NP7 network processor architecture, this update enhances threat prevention throughput by 21% compared to FortiOS 7.4.0. It serves as a feature-stable release for organizations requiring FIPS 140-3 compliance in government and financial networks.
