Introduction to FGT_200D-v5-build1064-FORTINET.out.zip

This firmware package provides critical security patches and performance optimizations for FortiGate 200D next-generation firewalls running FortiOS v5.2.x. Designed as a maintenance release under Fortinet’s Q3 2016 security update cycle, build 1064 resolves 4 high-severity CVEs while maintaining backward compatibility with legacy network configurations. The .zip archive contains verified firmware binaries and SHA-256 checksum files for integrity validation.

The update specifically targets organizations maintaining FortiGate 200D appliances in environments requiring PCI DSS 3.2 compliance, with enhanced logging stability for devices using flash-based storage. Compatible with both standalone and HA cluster deployments, it serves as the final planned update for the v5.2.x branch before end-of-support.
