​Introduction to FGT_900D-v6-build1803-FORTINET.out Software​

This firmware package delivers critical security patches and hardware-specific optimizations for FortiGate 900D enterprise firewalls running FortiOS 6.4.15. As part of Fortinet’s Q3 2024 Extended Security Maintenance (ESM) program, it addresses 9 CVEs while enhancing threat prevention performance for high-traffic networks.

The build supports FGT-900D hardware appliances operating in standalone or HA cluster configurations, specifically optimized for environments requiring sustained 100Gbps+ firewall throughput. Compatibility requires existing FortiOS 6.4.12 or newer installations with 4.8GB free storage partition space.
