Introduction to FGT_81E_POE-v7.2.2.F-build1255-FORTINET.out

Designed for small-to-medium business network security, ​​FGT_81E_POE-v7.2.2.F-build1255-FORTINET.out​​ delivers Fortinet’s Q2 2025 firmware update for FortiGate 81E-PoE appliances under FortiOS 7.2.2. This release focuses on resolving critical vulnerabilities while enhancing Power over Ethernet (PoE) management capabilities for distributed network environments.

Optimized for the FG-81E-PoE hardware platform with 4 Gbps firewall throughput capacity, this build addresses 11 CVEs identified in FortiGuard Labs’ May 2025 advisory. The firmware maintains backward compatibility with configurations from FortiOS 7.2.x while introducing hardware-accelerated security services for PoE-connected devices.


Key Features and Improvements
