Introduction to FGT_80E_POE-v7.4.3.F-build2573-FORTINET.out
The FGT_80E_POE-v7.4.3.F-build2573-FORTINET.out firmware package delivers critical security enhancements for Fortinet’s 80E-POE series next-generation firewalls, specifically optimized for small-to-medium business networks requiring Power over Ethernet (PoE) capabilities. Released under FortiOS 7.4.3’s Q2 2025 security maintenance cycle, this build resolves 6 CVEs identified in Fortinet’s April 2025 security advisories, including vulnerabilities in SSL/TLS decryption modules and SD-WAN path selection logic.
Designed for environments requiring both network security and PoE-powered device management, this update supports FortiGate 80E-POE appliances deployed in retail, education, and branch office scenarios. The build2573 revision introduces hardware-accelerated threat detection for IoT devices while optimizing power management for PoE-connected endpoints.
