Introduction to FGT_98D_POE-v6-build0365-FORTINET.out

This firmware package delivers critical security patches and network stability enhancements for FortiGate 98D-POE series firewalls running FortiOS v6. Designed for small-to-medium businesses requiring Power over Ethernet (PoE) support, build0365 resolves 9 CVEs while optimizing threat detection efficiency for distributed office deployments.

Exclusively compatible with 98D-POE hardware (FG-98D-POE), this Q4 2024 release maintains backward compatibility with FortiOS 6.4.x configurations. Network engineers managing retail or campus environments will benefit from its improved PoE device management and SD-WAN failover logic for 4G/LTE backup links.
