Introduction to FGT_200D-v5-build1220-FORTINET-5.4.10.out Software

The ​​FGT_200D-v5-build1220-FORTINET-5.4.10.out​​ firmware package delivers critical security updates and system stability enhancements for FortiGate 200D series firewalls. As part of Fortinet’s FortiOS 5.4 Long-Term Support (LTS) branch, this build addresses 7 CVEs while maintaining backward compatibility with legacy network configurations. Designed for mid-sized enterprises, it optimizes threat prevention capabilities for networks handling up to 5Gbps throughput.

This firmware exclusively supports FortiGate 200D hardware (P09340 series) running FortiOS 5.4.x. Released in Q3 2017, it resolves memory management issues observed in high-availability cluster deployments and improves VPN tunnel stability during firmware rollback operations.
