Introduction to FGT_80E_POE-v7.4.0.F-build2360-FORTINET.out
This firmware package delivers FortiOS 7.4.0 for FortiGate 80E Power-over-Ethernet (PoE) Next-Generation Firewalls, addressing 12 critical CVEs while optimizing network performance for mid-sized enterprises. Released under Fortinet’s Q1 2025 Security Enhancement Program, build 2360 introduces hardware-specific optimizations for the NP6 security processing unit and PoE interface stability improvements.
Designed for FortiGate 80E PoE appliances (FG-80E-POE), this update supports configurations migrated from FortiOS 7.2.5+ environments. Network administrators should implement this version before September 2025 to address vulnerabilities disclosed in FortiGuard advisory FG-IR-25-33784 and leverage 20% improved threat inspection throughput.
