Introduction to FWB_4000F-v700-build0111-FORTINET.out

The ​​FWB_4000F-v700-build0111-FORTINET.out​​ firmware package delivers enterprise-grade security enhancements for Fortinet’s 4000F-series next-generation firewalls, designed for hyperscale data centers and critical infrastructure networks. Released on March 3, 2025, this build (v7.0.0 build 111) introduces architectural optimizations for FortiOS 7.2 while maintaining backward compatibility with FortiOS 6.4.19+ deployments. It targets FortiGate 4000F, 4010F, and 4040F models requiring ultra-high throughput (up to 8,000 Mbps threat protection) and advanced SD-WAN orchestration capabilities.
