Introduction to FWB_4000F-v700-build0311-FORTINET.out Software
The FWB_4000F-v700-build0311-FORTINET.out firmware package represents Fortinet’s latest security enhancement for its FortiWeb 4000F series web application firewalls (WAF). Released under FortiOS 7.0.0 framework, this build (0311) addresses critical vulnerabilities while introducing performance optimizations for enterprise-grade web application protection. Designed specifically for the 4000F hardware appliance, this update aligns with Fortinet’s Q3 2024 security advisory cycle to combat evolving cyber threats targeting API endpoints and cloud-native applications.
Compatible exclusively with FortiWeb 4000F hardware models running FortiOS 7.0.x, this firmware revision (build 0311) was officially published on Fortinet’s support portal on August 15, 2024. It replaces the previous build 0297, which contained unresolved stability issues in high-traffic TLS decryption scenarios.
