Imperva Inc

A cybersecurity firm that shields businesses' web applications, data, and networks from hackers, with products including a web application firewall that filters traffic to block attacks, plus data security and DDoS-defense tools. Founded in 2002 by Shlomo Kramer and two partners under the name WebCohort, the company renamed itself Imperva in 2004—a nod to imperviousness, fitting for a firm built around keeping attackers out.
