Introduction to FGT_600D-v6-build1392-FORTINET.out Software
The FGT_600D-v6-build1392-FORTINET.out firmware delivers essential security patches and operational optimizations for FortiGate 600D series firewalls under FortiOS 6.4.12. Designed for enterprise networks requiring high availability, this release addresses critical vulnerabilities while enhancing hardware-accelerated threat prevention capabilities.
Compatible exclusively with the FortiGate 600D platform – a 1U rack-mounted appliance supporting up to 40 Gbps threat-protected throughput – this build was released in Q2 2025 as part of Fortinet’s quarterly security maintenance cycle. The 600D series leverages NP6 security processing units (SPUs) to maintain consistent performance for large-scale VPN and deep packet inspection workloads.
Key Features and Improvements
Security Enhancements
