Introduction to FWB_4000E-v700-build0365-FORTINET.out Software
The FWB_4000E-v700-build0365-FORTINET.out firmware package delivers critical security and performance updates for Fortinet’s FortiWeb 4000E series web application firewalls (WAF). Designed under FortiOS 7.0.0 architecture, this build (0365) specifically addresses vulnerabilities in API ecosystems and cloud-native application environments while optimizing TLS 1.3 processing efficiency.
Compatible exclusively with FortiWeb 4000E hardware appliances running FortiOS 7.0.5 or newer, this firmware resolves stability issues reported in build 0349 during high-concurrency SQL injection mitigation scenarios. Officially released on Fortinet’s support portal on April 25, 2025, it aligns with NIST SP 800-204B controls for federal cloud deployments and PCI DSS 4.0 compliance requirements.
