​​Introduction to FGT_1000D-v6-build1914-FORTINET.out Software​​

This firmware release (build 1914) targets FortiGate 1000D series appliances, delivering critical security updates and performance optimizations under FortiOS v6.4.13. Designed for enterprise networks requiring robust threat prevention, it addresses 23 CVEs identified in Fortinet’s Q1 2025 security advisories.
