Introduction to FGT_600E-v6-build0443-FORTINET.out.zip

This firmware release delivers critical security enhancements and operational optimizations for FortiGate 600E series next-generation firewalls. As part of FortiOS 6.4.3 maintenance updates, it addresses 9 Common Vulnerabilities and Exposures (CVEs) while improving SD-WAN application steering performance. The build specifically targets organizations requiring FIPS 140-3 compliance and enhanced threat intelligence integration.

Compatible with FortiGate 600E, 601E, and 602E hardware platforms, this version maintains backward compatibility with FortiOS 6.4.x configurations. The update supports hybrid cloud deployments through enhanced integration with FortiManager 7.4.5+ for centralized policy management.
