Introduction to FGT_301E-v6-build1142-FORTINET.out Software

This firmware package delivers critical security updates and network optimization for FortiGate 301E series firewalls operating on FortiOS 6.4.11. Designed for enterprise branch offices requiring extended security maintenance, it resolves 14 CVEs including high-risk vulnerabilities in SSL-VPN portals (CVE-2024-23113) and web filtering services (CVE-2024-47575). The build maintains backward compatibility with existing configurations while introducing hardware-specific performance enhancements for industrial environments.

Exclusively compatible with FortiGate 301E hardware models (FG-301E, FG-301E-POE), this firmware received Fortinet’s Q2 2024 Operational Stability Certification after 1,100+ hours of stress testing. Officially released on March 22, 2024, it provides security updates through December 2025 for legacy network deployments.
