​​Introduction to FGT_1200D-v6.M-build2060-FORTINET.out.zip​​

This firmware package delivers FortiOS 6.4.15 for FortiGate 1200D enterprise firewalls, focusing on critical security hardening and operational optimization for hyperscale network environments. Released under Fortinet’s Extended Vulnerability Support (EVS) program in Q1 2025, it addresses high-risk vulnerabilities while maintaining backward compatibility for legacy configurations in financial and cloud infrastructure deployments.

The ​​FGT_1200D-v6.M-build2060​​ update targets the 3U rack-mounted FortiGate 1200D (FG-1200D) appliance, supporting up to 50 Gbps threat inspection throughput. Designed for mission-critical data centers, this build bridges feature parity between FortiOS 6.x and modern 7.x security architectures while extending hardware lifecycle support.
