Introduction to FWB_100D-v700-build0140-FORTINET.out Software
The FWB_100D-v700-build0140-FORTINET.out firmware package delivers critical infrastructure protection updates for Fortinet’s entry-level FortiWeb 100D web application firewall appliances. Released on May 12, 2025, this build (v700-build0140) addresses 7 high-risk CVEs while introducing hardware-accelerated threat mitigation for SMB network environments.
This security-focused update enhances the 100D series’ 20 Gbps HTTP/HTTPS inspection capabilities through optimized pattern matching algorithms. It maintains backward compatibility with FortiOS 7.0.7+ for centralized policy synchronization across distributed network architectures.
