Proofpoint Acquires Israeli Cybersecurity Firm Varonis for $6.3 Billion

American cybersecurity firm Proofpoint has entered into a definitive agreement to acquire Israel's Varonis Systems for approximately $6.3 billion. The deal, approved by the boards of directors of both companies, aims to create a unified platform for managing critical data and artificial intelligence algorithms. Each Varonis shareholder will receive $49.75 per share. The combined entity will serve over 16,000 corporate clients globally.

Varonis Systems, founded by Israeli entrepreneurs Yaki Feitelsohn and Ohad Korkus, specializes in automated protection of sensitive files, detecting suspicious user activity, unauthorized access, and preventing data leaks. The company's solutions utilize machine learning to monitor data usage by employees and digital agents. Varonis employs about a thousand specialists at its Israeli research center, which plays a crucial role in developing the company's core technologies.

Company leadership stated that the merger will accelerate the deployment of new products for securing cloud services and corporate networks. The acquisition comes amid increasing challenges in the digital security market due to the rapid spread of generative AI, which creates vulnerabilities as automated bots and applications gain access to sensitive knowledge bases. The new Proofpoint-Varonis platform is designed to mitigate these risks through continuous monitoring of digital rights and communication channels.

The transaction is subject to standard regulatory approvals and a shareholder meeting. The deal is expected to close in the first half of 2027. Until then, both companies will continue to operate independently. Following the acquisition's finalization, Varonis securities will be delisted from the Nasdaq exchange and become privately held.
