​​Introduction to FGT_200D-v5-build1100-FORTINET.out.zip Software​​

This firmware package provides essential updates for FortiGate 200D next-generation firewalls running FortiOS 5.x series, originally released in Q4 2016 as part of extended lifecycle support for enterprise networks. Designed for mid-sized organizations handling 5Gbps+ throughput, the build addresses 18 documented security vulnerabilities while maintaining compatibility with legacy security policies and hardware configurations.

The firmware specifically targets FortiGate 200D hardware appliances (FG-200D) with dual power supply units, supporting hybrid deployments across SD-WAN and traditional network architectures. It serves as a critical stability update between FortiOS 5.2 and 5.4 releases, particularly valuable for organizations requiring extended support beyond standard product lifecycles.
