Introduction to FGT_81E_POE-v7.2.5.F-build1517-FORTINET.out

This firmware release (build 1517) delivers critical security and Power over Ethernet (PoE) management updates for FortiGate 81E-POE next-generation firewalls, specifically designed for small-to-medium business networks requiring combined security and PoE switching capabilities. As part of FortiOS 7.2.5.F’s security architecture, it resolves 8 CVEs identified in SSL-VPN and IPS components while introducing enhanced 802.3bt Type 4 PoE device management.

Compatible exclusively with FortiGate 81E-POE hardware (FG-81E-POE), this Q2 2025 release achieves FIPS 140-3 Level 2 compliance and supports automated IoT device profiling through FortiNAC integration. Network administrators managing retail stores or campus networks will benefit from its 95W total PoE budget management and temperature-regulated power delivery.
