Introduction to FGT_80E_POE-v6-build0457-FORTINET.out

The ​​FGT_80E_POE-v6-build0457-FORTINET.out​​ firmware package provides essential security updates and operational optimizations for Fortinet’s FortiGate 80E-POE series firewalls. Designed for small-to-medium businesses with Power over Ethernet (PoE) requirements, this build (0457) resolves vulnerabilities identified in Q1 2025 while enhancing threat prevention efficiency.

This release specifically targets the ​​FortiGate 80E-POE​​ appliance (FG-80E-POE), a compact 1U device offering 1.5 Gbps firewall throughput and 16 PoE ports. The firmware maintains compatibility with FortiOS 6.4.x lifecycle policies and integrates with FortiManager 6.4+ for centralized security management.
