Introduction to FGT_200D_POE-v6-build0131-FORTINET.out

This firmware update provides critical security enhancements for FortiGate 200D-POE series next-generation firewalls operating on FortiOS 6.4.x. Developed under Fortinet’s Extended Security Maintenance program, build 0131 addresses 11 documented vulnerabilities while preserving backward compatibility with legacy configurations.

​​Primary Compatibility​​

  • ​​Hardware Models​​: FG-200D-POE, FG-200D-POE-DC
  • ​​FortiOS Baseline​​: 6.4.28 through 6.4.31
  • ​​Deployment Scenarios​​:
    • Enterprise branch office security with Power-over-Ethernet support
    • PCI-DSS compliant retail payment systems
    • Healthcare networks requiring HIPAA-compliant encryption

First released on March 12, 2025, this update extends technical support for organizations maintaining FortiOS 6.4.x deployments during phased migrations to 7.x platforms.
