Helps organizations protect their environment from DDoS attacks at layers 3 and 4. The cloud-based Imperva solution is fully automated and provides only a 3-second SLA for attack mitigation. The product can be used to protect any online resources such as websites, DNS servers, SMTP servers, and any other IP-based applications. This service leverages Imperva's multi-terabit network bandwidth and packet processing capabilities to absorb and mitigate the largest and most sophisticated DDoS attacks.
Similar to DDoS Protection for Networks, it helps organizations protect their environment from DDoS attacks at layers 3 and 4 for specific IP addresses. The service is suitable for organizations that do not have a Class C network or network equipment with BGP capabilities required to use the Infrastructure Protection service.
Imperva's DNS solutions protect against attacks while also providing query acceleration through caching and load reduction. Imperva can serve as a record host and authoritative DNS, providing final responses to queries while protecting against volumetric attacks. The Imperva secure DNS proxy server terminates TCP and UDP connections, acting as a buffer between the Internet and the original name server, filtering all kinds of DDoS attacks such as SYN Floods and UDP Floods. Only legitimate DNS queries are forwarded to the origin server. Layer 7 DDoS attacks are mitigated by a dedicated engine that can distinguish between legitimate DNS queries and DDoS attempts.
