Introduction to FGT_201E-v6-build1364-FORTINET.out.zip Software
This firmware release (FortiOS 6.4.12 Build 1364) provides critical security hardening and operational optimizations for FortiGate 201E series appliances, designed for small-to-medium enterprise network protection. Released through Fortinet’s validated update channel in March 2025, it resolves 15 CVEs identified in previous versions while introducing IoT device visibility enhancements and SD-WAN traffic prioritization improvements.
The build specifically targets FG-201E hardware models running FortiOS 6.4.x. As a security maintenance update, it addresses certificate validation vulnerabilities reported in FortiOS 6.4.11 and enhances compatibility with FortiManager 7.6.3’s policy automation framework. The update is optimized for environments requiring FIPS 140-3 compliance in education and retail sectors.
