Introduction to FGT_600D-v5-build1064-FORTINET.out.zip

This firmware package delivers critical security enhancements for FortiGate 600D series appliances, specifically addressing vulnerabilities identified in previous FortiOS 5.6.x releases. Designed for enterprise perimeter security deployments, build 1064 improves threat prevention capabilities while maintaining compatibility with legacy network configurations.

The 600D platform now supports 3.5 Gbps firewall throughput and 1.2 Gbps VPN performance, making this update essential for organizations requiring NGFW functionality with UTM services. Compatible with FortiOS 5.6.4, this release maintains backward compatibility with 5.6.2 configurations but discontinues support for 5.4.x environments.
