​​Introduction to FGT_3200D-v6.M-build2060-FORTINET.out Software​​

This firmware update (version 6.M-build2060) delivers critical security enhancements and performance optimizations for the FortiGate 3200D next-generation firewall, designed for enterprise-grade network protection. Released on May 10, 2025, it resolves 18 CVEs identified in prior FortiOS versions while introducing advanced SD-WAN telemetry capabilities required for hybrid infrastructure management.

Compatible exclusively with FortiGate 3200D appliances running FortiOS 6.M, this build supports backward configuration migration from 6.4.x releases. Its redesigned packet-processing engine achieves 420 Gbps firewall throughput – a 15% improvement over build 2043, as validated by Fortinet’s internal benchmarks.

​​Key Features and Improvements​​
