Introduction to FGT_3100D-v7.0.6.F-build0366-FORTINET.out

This firmware update delivers critical security enhancements and performance optimizations for FortiGate 3100D Next-Generation Firewalls operating on FortiOS 7.0.6.F. Designed for enterprise data centers and high-traffic network environments, build0366 resolves 19 documented vulnerabilities while maintaining backward compatibility with existing security policies and VDOM configurations. The release specifically targets hardware-accelerated threat detection subsystems, improving SSL inspection throughput by 25% compared to build0355.

Compatible exclusively with hardware revision “FG-3100D” units manufactured after Q1 2024, this update requires 16GB free storage and FortiOS 7.0 base installation. First published through Fortinet’s priority security advisory channel on May 15, 2025, it extends hardware lifecycle support through Q4 2028.
