​​Introduction to FGT_1200D-v7.0.3-build0237-FORTINET.out​​

The ​​FGT_1200D-v7.0.3-build0237-FORTINET.out​​ firmware is a security-enhanced maintenance release for Fortinet’s ​​FortiGate 1200D​​ enterprise firewall, designed for high-performance network environments requiring 40Gbps threat protection throughput. As part of the FortiOS 7.0.3 patch series, this build resolves critical vulnerabilities while maintaining backward compatibility with existing SD-WAN configurations.

This release follows Fortinet’s quarterly security update cycle, prioritizing urgent exploit mitigation for enterprise networks. It supports configurations from FortiOS 7.0.x but requires hardware validation for legacy 6.4.x deployments.
