Introduction to FGT_900D-v6-build1263-FORTINET.out Software

This enterprise-grade firmware package delivers critical security updates and network optimizations for Fortinet’s FortiGate 900D Next-Generation Firewall. Released under FortiOS 6.2.10 maintenance updates in Q1 2025, it resolves 7 CVEs including critical SSL-VPN vulnerabilities while enhancing hyperscale network protection for enterprise core infrastructures.

The firmware exclusively supports FortiGate 900D appliances with hardware revision 07-900D-xxxx, requiring 32GB RAM and 512GB RAID storage for full operation. It maintains backward compatibility with FortiOS 6.0.x configurations but mandates clean installation when upgrading from versions below 6.0.4.
