The Fortinet FortiWeb 4000F is a Web Application Firewall (WAF) that inspects HTTP/HTTPS traffic to protect web applications and APIs from OWASP Top 10 attacks, bot abuse, and zero-day exploits. It is typically deployed by the largest enterprise data centers, carriers, and service providers.

The FortiWeb 4000F is rated for up to 70 Gbps of protected WAF throughput. Actual throughput depends on which inspection features (SSL offload, deep content inspection, bot mitigation) are enabled.

The 4000F is a current, actively sold model — the flagship of Fortinet's F-series lineup.

Yes. FortiWeb supports Active-Passive and Active-Active HA clustering so you can eliminate single points of failure in front of production web applications.
