​​Introduction to FGT_1200D-v6-build0335-FORTINET.out.zip Software​​

The FGT_1200D-v6-build0335-FORTINET.out.zip firmware package delivers FortiOS 6.4.12 for FortiGate 1200D enterprise firewalls, targeting critical network infrastructure security gaps while optimizing high-throughput environments. Officially released on August 15, 2024 (based on build metadata), this update addresses 14 CVEs documented in Fortinet’s Q3 2024 Security Advisory.

Designed for data center and carrier-grade deployments, the firmware enhances BGP/OSPF routing stability and introduces hardware-specific optimizations for the 1200D’s NP6 network processors. Enterprises requiring compliance with DISA STIG guidelines will benefit from its FIPS 140-3 Level 2 validated cryptographic modules.
