1. Introduction to FGT_81E_POE-v6-build0932-FORTINET.out

This firmware package provides essential security updates and performance enhancements for FortiGate 81E-POE series firewalls, specifically designed for small-to-medium enterprises requiring Power over Ethernet (PoE) capabilities. Released under FortiOS 6.x architecture, it addresses 12 critical vulnerabilities identified in Fortinet’s Q1 2025 security advisories while maintaining backward compatibility with existing network configurations.

Targeting branch office deployments with integrated switch ports, this build optimizes threat protection for IoT devices and VoIP systems. Compatible exclusively with FortiGate 81E-POE hardware (FG-81E-POE), it requires minimum 4GB RAM and FortiOS 6.2.0+ baseline installations for deployment.
