Introduction to FGT_140E_POE-v7.4.1.F-build2463-FORTINET.out

This firmware package delivers FortiOS 7.4.1 for FortiGate 140E Power-over-Ethernet (PoE) security appliances, addressing 9 critical CVEs while optimizing network performance for distributed enterprise environments. Released under Fortinet’s Q2 2025 Security Enhancement Initiative, build 2463 introduces hardware-specific optimizations for the NP6lite security processor and PoE stability improvements.

Designed specifically for FortiGate 140E PoE models (FG-140E-POE), this update resolves SSL-VPN session hijacking vulnerabilities disclosed in FortiGuard advisory FG-IR-25-33891 while enhancing threat detection accuracy by 18% compared to previous releases. System administrators managing retail networks or branch offices should prioritize this update before October 2025 to maintain PCI-DSS 4.0 compliance.
