Introduction to FGT_800D-v7.2.2.F-build1255-FORTINET.out

This critical firmware update addresses 8 high-risk vulnerabilities in FortiGate 800D next-generation firewalls while optimizing enterprise network performance for multi-gigabit environments. Released under Fortinet’s Q2 2025 security advisory (FG-IR-25-044), the build provides mandatory protection for financial institutions and healthcare networks handling sensitive data transmission.

Designed exclusively for FortiGate 800D appliances running FortiOS 7.2.x, this update resolves configuration conflicts observed in high-availability cluster deployments exceeding 5Gbps throughput. Network engineers managing data center edge security or multi-campus networks should prioritize installation before September 2025 per Fortinet’s vulnerability remediation timeline.
