Introduction to FGT_201E-v6-build0302-FORTINET.out.zip

This firmware update (v6.0.3, build0302) delivers critical security patches and operational enhancements for FortiGate 201E next-generation firewalls. Designed for enterprise branch office deployments, it addresses vulnerabilities in SSL-VPN services while optimizing traffic handling for SD-WAN architectures. Released in March 2023, this build specifically resolves memory allocation issues affecting high-availability clusters and introduces granular controls for Zero Trust Network Access implementations.

The package supports FortiGate 200E/201E hardware platforms running FortiOS 6.0.x, with backward compatibility for configurations migrated from v5.6.5+ versions. System administrators should allocate 15 minutes for installation and verify 2GB of available flash storage before proceeding.
