Introduction to FGT_81F_POE-v7.2.5.F-build1517-FORTINET.out Software

This firmware package delivers essential security updates and operational optimizations for Fortinet’s FortiGate 81F-POE next-generation firewall, specifically engineered for power-over-Ethernet (PoE) enabled network environments requiring advanced threat protection. As part of FortiOS 7.2.5’s security maintenance release cycle, build 1517 resolves 12 CVEs identified in Fortinet’s Q1 2025 PSIRT advisories while enhancing power management capabilities for PoE-connected devices.

Designed exclusively for the 81F-POE hardware platform, this update introduces hardware-accelerated deep packet inspection for PoE traffic streams and maintains backward compatibility with FortiManager 7.4.6+ for centralized configuration management.
