Introduction to FGT_81F_POE-v7.2.6.F-build1575-FORTINET.out Software

This firmware package delivers FortiOS 7.2.6 Feature Release (7.2.6.F) for the FortiGate 81F-POE desktop firewall, optimized for small-to-medium businesses requiring Power over Ethernet (PoE) capabilities alongside enterprise-grade security. Released under Fortinet’s Q2 2025 security update cycle, build1575 addresses critical vulnerabilities while introducing hardware-accelerated TLS 1.3 decryption for PoE-enabled network environments.

The FortiGate 81F-POE platform supports 16 PoE+ ports with 370W power budget, making it ideal for IP camera deployments and VoIP systems. This firmware maintains backward compatibility with FortiOS 7.0.x configurations but enforces FIPS 140-3 Level 2 encryption standards for government-regulated industries.
