All-inclusive DDoS protection

Imperva DDoS protection supports Unicast and Anycast technologies, powering a many-to-many defense methodology. This automatically detects and mitigates attacks exploiting application and server vulnerabilities, hit-and-run events and large botnets.


3-second mitigation SLA

When DDoS strikes, it takes a targeted website moments to go down and hours to recover. Imperva offers the only service that has an SLA-backed guarantee to detect and block any website attack, of any size or duration — in 3 seconds or less.

High-capacity network
