1. Introduction to FGT_80E_POE-v6-build1911-FORTINET.out Software

This firmware release (build 1911) delivers critical updates for FortiGate 80E-POE devices running FortiOS 6.4.9, designed to address enterprise security demands and optimize network operations. As part of Fortinet’s Q4 2024 maintenance cycle, it resolves 23 CVEs identified in previous versions while enhancing Power over Ethernet (PoE) management capabilities for IoT device deployments.

Compatible exclusively with FortiGate 80E-POE models manufactured after 2021, this update maintains backward compatibility with configurations from FortiOS 6.4.6+. The build underwent 1,200+ regression tests across 45 network topologies before public release on November 15, 2024.
