Introduction to FWB_400D-v700-build0124-FORTINET.out Software
The FWB_400D-v700-build0124-FORTINET.out firmware package delivers critical security and operational enhancements for Fortinet’s mid-range FortiWeb 400D web application firewalls. Released on May 10, 2025, this update specifically targets API security gaps in hybrid cloud environments while optimizing resource utilization for medium-scale enterprises. Designed for organizations handling sensitive healthcare or financial data, it integrates with FortiOS 7.8.x ecosystems to enforce granular access controls over east-west traffic.
Exclusively compatible with FortiWeb 400D hardware appliances (models FWB-400D and FWB-400DDC), this firmware requires FortiOS 7.6.7+ as a baseline. The “v700-build0124” identifier aligns with Fortinet’s 2025 Q2 security framework, emphasizing automated threat response workflows and FIPS 140-3 compliance.
