Introduction to FGT_1200D-v6.M-build2060-FORTINET.out
This firmware package delivers critical security updates and performance enhancements for FortiGate 1200D series firewalls, specifically designed to address emerging network threats while maintaining enterprise-grade throughput. As part of FortiOS 6.4.11 maintenance release (build 2060), it extends the lifecycle support for the 1200D platform deployed in high-traffic data centers and ISP environments.
Compatible exclusively with FortiGate 1200D, 1200D-POE, and 1200D-FPOE models, this March 2023 release introduces hardened SSL-VPN protocols and improved memory allocation for sustained operation under 20 Gbps firewall stress conditions. The build number “v6.M” confirms its classification as a Medium Severity patch under Fortinet’s firmware categorization system.
