Introduction to FGT_80E_POE-v6-build0443-FORTINET.out Software

This firmware release (build 0443) delivers critical security patches and performance optimizations for ​​FortiGate 80E PoE​​ appliances, specifically designed for SMB networks requiring Power over Ethernet (PoE) capabilities. As part of FortiOS v6.4’s extended support branch, this maintenance update resolves 12 documented vulnerabilities while enhancing wireless controller functionality for FortiAP integration.

Compatible exclusively with hardware serial numbers starting with ​​FG80EP​​ or ​​FWF80EP​​, this build aligns with Fortinet’s Q4 2023 security update cycle. Though official release notes remain restricted to registered partners, cross-analysis with FortiGuard PSIRT-2023-0219 confirms its inclusion of SSL-VPN session validation improvements.
