Imperva, originally named WEBcohort, was founded in 2002 by Shlomo Kramer, Amichai Shulman and Mickey Boodaei.[1] The following year the company shipped its first product, SecureSphere Web Application Database Protection, a web application firewall.[2] In 2004, the company changed its name to Imperva.[3]

In 2011, Imperva went public and was listed on the New York Stock Exchange (NYSE: IMPV).[4] 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.[5]

In 2016, Imperva published a free scanner designed to detect devices infected with, or vulnerable to, the Mirai botnet.[6] In February 2017, Imperva sold Skyfence to Forcepoint for $40 million.[7] In February 2017, Imperva purchased Camouflage, a data masking company.[8]

In August 2017, Imperva named Chris Hylen, the former CEO of Citrix GetGo, as its new president and CEO.[9] Imperva's former CEO, Anthony Bettencourt, resigned as chairman of the board of directors in February 2018.[10] In August 2018, Imperva acquired Prevoty, a runtime application self-protection (RASP) security company.[11] 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.[12]

In 2019, Imperva was acquired by private equity firm Thoma Bravo.[13]
