Introduction to FGT_800D-v6-build1914-FORTINET.out Software
This firmware package provides critical updates for FortiGate 800D series enterprise firewalls running FortiOS 6.x. As part of Fortinet’s Q1 2025 extended security maintenance program, build 1914 combines vulnerability remediation with hardware resource optimization for high-performance network environments.
Compatible Devices:
- FortiGate 800D (all hardware revisions with NP6 ASIC)
- FortiGate 801D (in v6.x backward compatibility mode)
The release follows Fortinet’s firmware lifecycle policy for enterprise-class devices, compiled in March 2025. It serves as a cumulative maintenance update rather than a major OS version upgrade.
