Introduction to FGT_400D-v6-build1010-FORTINET.out Software
This firmware package delivers critical security enhancements and operational optimizations for FortiGate 400D series appliances running FortiOS 6.2.2. Released in Q1 2024 under build 1010, it addresses 12 documented vulnerabilities while maintaining backward compatibility with existing network configurations. Designed for medium-sized enterprise deployments, the update enhances threat protection for networks handling 1-2 Gbps throughput with full UTM/IPS inspection enabled.
The firmware exclusively supports FortiGate 400D hardware models (FG-400D), requiring 4GB RAM and 128GB SSD storage. This release aligns with Fortinet’s quarterly security maintenance cycle, resolving vulnerabilities identified through FortiGuard Labs’ global threat monitoring network. The build specifically targets performance improvements for environments using IPsec VPN tunnels and SD-WAN architectures.
