Varonis being acquired by Proofpoint signals more cybersecurity M&A, Wedbush says

Cybersecurity firm Proofpoint Inc., owned by Thoma Bravo, has agreed to acquire data security company Varonis Systems Inc. for approximately $6.3 billion in cash, according to Bloomberg. Varonis was initially speculated to be a potential target for private equity firms, including Blackstone, Thoma Bravo, and Vista Equity Partners, with Proofpoint ultimately emerging as the buyer in September.

The purchase price represents a 52% premium to Varonis' stock price prior to the news. Varonis, founded in 2005, initially focused on mapping which users could access specific files on corporate servers. The company now emphasizes artificial intelligence security solutions. This acquisition marks a significant milestone for Proofpoint, which has made several high-profile purchases since taking the company private in 2021.

Varonis' software and expertise in data mapping and access controls will complement Proofpoint's existing offerings in email, collaboration, and data loss prevention. The combined entity will serve over 16,000 enterprises. Proofpoint CEO Sumit Dhawan highlighted the importance of AI in enhancing data value and risk. The deal is expected to close in the first half of 2027, subject to regulatory approval and shareholder consent.
