Information security software firm Imperva has entered into a definitive agreement to be acquired by American private-equity technology investment firm Thoma Bravo in a transaction valued at approximately $2.1 billion.

Headquartered in Redwood City, California, with development offices in Tel Aviv and Rehovot, Imperva was founded in 2002 as WEBcohort by Israeli cybersecurity experts Shlomo Kramer, Amichai Shulman and Mickey Boodaei. Imperva will delist from NASDAQ and operate as a privately held company under its current executive team upon the close of the acquisition deal late this year or early next year.

“Thoma Bravo has long admired Imperva’s innovative products and strong market position,” said Seth Boro, a managing partner at Thoma Bravo. “As a leading company that protects data and applications, regardless of whether they live in the cloud, on-premise or in a hybrid environment, Imperva is ahead of the curve from the rest of the cybersecurity industry, and we’re thrilled with this exciting partnership.”

Imperva’s Incapsula, SecureSphere, and CounterBreach product lines help organizations protect websites, applications, APIs and databases from cyberattacks while ensuring compliance. It counts 6,200 customers and 500 partners in more than 100 countries.
