Introduction to FWB_400D-v700-build0111-FORTINET.out Software
The FWB_400D-v700-build0111-FORTINET.out firmware package provides essential security updates and performance enhancements for Fortinet’s FortiWeb 400D series web application firewalls. Released on March 9, 2025, this build (v700-build0111) addresses critical vulnerabilities while introducing advanced threat detection mechanisms for enterprise web infrastructure protection.
Designed for medium-sized businesses, this update supports the FortiWeb 400D hardware platform, capable of inspecting up to 140 Gbps of HTTP/HTTPS traffic. It integrates with Fortinet’s Security Fabric ecosystem, enabling centralized policy management through FortiManager 7.6.5+ and real-time log analysis via FortiAnalyzer 7.4.9+.
