Imperva

Imperva is a cyber security software and services company which provides protection to enterprise data and application software. The company is headquartered in Redwood Shores, California.

Imperva, originally named WEBcohort, was founded in 2002. The following year the company shipped its first product, SecureSphere Web Application Database Protection, a web application firewall. In 2004, the company changed its name to Imperva.

In 2014, the company acquired the remaining shares of Incapsula, a cloud security gateway startup named SkyFence, and real-time mainframe security auditing agents from Tomium Software.

In 2016, Imperva published a free scanner designed to detect devices infected with, or vulnerable to, the Mirai botnet. In February 2017, Imperva sold Skyfence to Forcepoint for $40 million. In February 2017, Imperva purchased Camouflage, a data masking company.

In August 2018, Imperva acquired Prevoty, a runtime application self-protection (RASP) security company. Also in 2018, Imperva identified a bug in the popular web browser Google Chrome which had been allowing attackers to steal information via HTML tags for audio and video files.

Imperva also suffered a breach of their own when notified customers that it learned on Aug. 20 about a security incident that exposed sensitive information for some users of Incapsula, the company’s cloud-based Web Application Firewall (WAF) product.

In 2019, Imperva was acquired by private equity firm Thoma Bravo.
