Proofpoint said it has signed a firm agreement to buy Varonis. CyberScoop reported that the cash price is about $6.3 billion and the deal was agreed on Thursday. By CyberScoop's account, Varonis finds a company's sensitive files, tracks who has access to them, and watches how they are used. Proofpoint, which CyberScoop says Thoma Bravo owns, built its business on blocking phishing and similar attacks aimed at employees.
Proofpoint's CEO, Sumit Dhawan, wrote that firms now give AI agents access to sensitive data. He said these agents can read and move huge amounts of it in seconds. His stated priority is protecting data from misuse by people or agents. Proofpoint says it plans to join Varonis's tools with its own for insider risk, data loss prevention and AI oversight. CyberScoop said Varonis's board approved the deal unanimously. Closing is expected in the first half of 2027, pending shareholder and regulator approval. The sources say nothing on products, contracts or prices.
The deal bets that data reachable by AI agents is now a main place to focus security. Dhawan promised less complexity, lower costs and fewer vendors, but that is a goal, not a result. Customers of either firm can ask now how current contracts will change, how the tools will connect, and what pricing will look like after closing.
