​​Introduction to FGT_1800F-v6.M-build2060-FORTINET.out Software​​

This firmware package (version 6.M-build2060) delivers critical security updates and functional enhancements for FortiGate 1800F next-generation firewalls, specifically designed for high-performance enterprise networks. Released on May 10, 2025, it addresses 23 CVEs identified in previous FortiOS versions while introducing new SD-WAN telemetry capabilities required for modern hybrid infrastructure.

The software supports FortiGate 1800F appliances running FortiOS 6.M branch, with backward compatibility for configurations migrated from 6.4.x releases. Its optimized memory management system enables sustained 320 Gbps firewall throughput – a 12% improvement over build 2049 according to Fortinet lab benchmarks.
