Introduction to FGT_140D-v6-build0365-FORTINET.out

The ​​FGT_140D-v6-build0365-FORTINET.out​​ firmware package delivers critical security updates and operational optimizations for FortiGate 140D series next-generation firewalls. As part of FortiOS 6.0.6’s Q4 2024 maintenance cycle, this build addresses vulnerabilities while maintaining backward compatibility for small-to-medium enterprises requiring extended hardware lifecycle support. Designed for branch offices and distributed networks, the FortiGate 140D series supports 3 Gbps firewall throughput and 800 Mbps SSL inspection capacity.

This firmware exclusively supports ​​FortiGate 140D appliances​​, featuring 8x1G RJ45 ports and redundant power supply configurations. Its compact 1U form factor makes it ideal for space-constrained deployments requiring enterprise-grade security.
