1. Introduction to FGT_81F_POE-v7.0.11.M-build0489-FORTINET.out

This firmware release (​​FGT_81F_POE-v7.0.11.M-build0489-FORTINET.out​​) delivers critical PoE device management upgrades and security enhancements for FortiGate 81F-POE firewalls. Designed for enterprise branch networks requiring 15Gbps threat prevention throughput with Power over Ethernet (PoE) support, it addresses 6 CVEs while introducing hardware-accelerated TLS 1.3 inspection and dynamic SD-WAN path selection. Released under Fortinet’s Q1 2025 security advisory cycle, this build requires FortiOS 7.0.11 as a baseline and supports advanced IoT device segmentation through automated PoE port management.
