Proofpoint has signed an agreement to acquire Varonis, a provider of Data Security, for a total cash amount of approximately 6,300 million USD. This acquisition aims to integrate data protection and AI security onto a single platform. Proofpoint, which is a company in the investment portfolio of Thoma Bravo, will purchase Varonis at a price of 49.75 USD per share, representing a total value of around 6,300 million USD.
Proofpoint views the current trajectory of AI Agents accessing critical data and operating across various systems as an increasing trend. By linking communication, Identity, access rights, data, and AI together, the companies believe they can enhance visibility of risks and accelerate response times. Both companies have complementary solutions, with Varonis providing a platform that allows organizations to automatically visualize and control critical data regardless of its location, covering AI security from code level to runtime, along with 24-hour Managed Detection and Response services.
On the other hand, Proofpoint focuses on protecting connections between individuals, data, and AI Agents through Cloud email and Collaboration tools. After the merger, both companies plan to create a single platform that searches for and protects critical data, controls what both individuals and AI can access, and prevents data leaks. Currently, Proofpoint serves over 80 clients in the Fortune 100 and more than 14,000 large organizations. Combined with Varonis, they will have over 16,000 enterprise clients worldwide.
The deal has received unanimous approval from the board of directors of Varonis and is expected to be completed in the first half of 2027, pending approval from Varonis shareholders and regulatory agencies. In the meantime, both companies will continue to operate independently. Once the deal is finalized, Varonis will become a private company, and Proofpoint plans to integrate the capabilities of both companies, align their marketing strategies, and accelerate the delivery of the combined platform to customers.
