Proofpoint agrees to buy cybersecurity firm Varonis for US$6.3 billion

All-cash deal for Varonis

6.3 billion US$

The companies announced the all-cash deal on Thursday. Proofpoint, an American cybersecurity firm, is owned by the private equity firm Thoma Bravo.

Varonis, founded in 2004, makes cloud software that helps businesses find sensitive data, limit access to it and detect threats. It employs about 2,800 people, around 1,000 of them in Israel.

"As AI becomes embedded across the enterprise, the data it can access determines both its value and its risk," said Proofpoint CEO Sumit Dhawan.
