Introduction to FGT_90D_POE-v6-build0443-FORTINET.out

This firmware update delivers critical network protection enhancements for Fortinet’s Power over Ethernet (PoE) enabled FortiGate 90D next-generation firewall. Designed for small-to-medium business deployments, build 0443 addresses multiple vulnerabilities identified in FortiOS 6.2.x while optimizing hardware resource utilization for PoE-powered network environments.

Exclusively compatible with FortiGate 90D-POE hardware models (FG-90D-POE series), this release follows Fortinet’s extended security maintenance cycle for v6.2 firmware. The version identifier confirms integration with FortiOS 6.2.9 architecture, incorporating backported security fixes from later firmware branches.
