​​Introduction to FGT_301E-v6-build0932-FORTINET.out.zip Software​​

This firmware release (FortiOS 6.4.5 Build 0932) provides essential security hardening and operational optimizations for FortiGate 301E series appliances, designed for enterprise branch office deployments. Officially released in January 2025 through Fortinet’s validated update channel, it resolves 19 CVEs identified in previous versions while introducing IoT device visibility enhancements and SD-WAN traffic prioritization improvements.

The build specifically targets FG-301E hardware models running FortiOS 6.4.x. As a security-focused update, it addresses certificate validation vulnerabilities reported in FortiOS 6.4.4 and enhances integration with FortiManager 7.6.3’s policy automation framework.
