Founded in 2002, Imperva was originally named WEBcohort before its renaming in 2004. The company went public in 2011 and acquired Incapsula in 2015. Today, the company focuses on distributed denial of service (DDoS) protection, Website security, content delivery and load balancing.
Imperva, like other vendors, uses a multi-tier approach to blocking DDoS traffic. Imperva Incapsula filters traffic through a web application firewall, a DDoS rules engine, and a series of progressive challenges. The process is said to be invisible to legitimate traffic, and legitimate visitors will not encounter latency, CAPTCHAs or wait screens.
