Introduction to FWB_100D-v700-build0162-FORTINET.out

The ​​FWB_100D-v700-build0162-FORTINET.out​​ firmware package delivers critical security enhancements for Fortinet’s 100D-series enterprise firewalls, designed for small-to-medium businesses requiring advanced threat prevention and VPN optimization. Released on May 5, 2025, this build (v7.0.0 build 162) introduces foundational updates for FortiOS 7.4 compatibility while maintaining backward compatibility with FortiOS 6.4.25+ deployments. Specifically engineered for FortiGate 100D, 101D, and 104D models, it addresses 15 CVEs while optimizing hardware resources for 10Gbps threat inspection throughput.
