​​Introduction to FWF_81F_2R_3G4G_POE-v6.M-build2000-FORTINET.out​​

This firmware package (v6.M-build2000) delivers critical security hardening and hardware-specific optimizations for Fortinet’s FortiWeb 81F series Web Application Firewalls with Power-over-Ethernet (PoE) and 4G/LTE failover capabilities. Released under FortiOS 6.4’s extended support framework, it addresses emerging vulnerabilities in converged network environments while maintaining backward compatibility with legacy security policies.

Specifically engineered for the dual-radio (2R) 3G/4G-enabled FWF-81F-POE appliance, this update enhances cellular failover resilience and complies with NIST SP 800-218 Secure Software Development standards. Officially released on May 12, 2025, it targets distributed enterprises requiring uninterrupted web application protection in power-constrained environments.

​​Key Features and Improvements​​

​​1. Converged Network Security​​

  • Mitigates 6 CVEs rated 8.2+ CVSS, including:
