Introduction to FGT_98D_POE-v6-build0484-FORTINET.out
The FGT_98D_POE-v6-build0484-FORTINET.out firmware package delivers critical security updates and operational optimizations for Fortinet’s FortiGate 98D-POE next-generation firewall appliances. Released under FortiOS 6.4.x lifecycle maintenance in Q2 2025, this build (0484) addresses vulnerabilities disclosed in Fortinet’s Q1 2025 security advisories while enhancing threat detection efficiency for medium-scale enterprise networks.
Designed exclusively for the FortiGate 98D-POE model (FG-98D-POE), this update integrates with Fortinet’s Security Fabric architecture, supporting advanced Unified Threat Management (UTM) services. The hardware appliance features 5 Gbps firewall throughput and 24x PoE+ ports, making it ideal for campus networks requiring high-density device connectivity.
