Proofpoint to Acquire Varonis in $6.3 Billion Deal to Forge Data and AI Security Powerhouse
Proofpoint, a Thoma Bravo portfolio company focused on human and agent cybersecurity, has entered into a definitive agreement to acquire data and AI security firm Varonis Systems in an all-cash deal valued at approximately $6.3 billion. The acquisition brings together two prominent enterprise security players to build a comprehensive cybersecurity platform designed to counter AI-accelerated threats, manage identities and communications, and secure critical enterprise data.
Under the transaction terms, Varonis shareholders will receive $49.75 per share in cash. The offer marks a 52% premium over Varonis’ closing price of $32.71 on June 22, 2026, before initial market reports surfaced, and a 17% premium over its $42.35 close on September 1, 2026. The transaction prices Varonis at roughly 8.4x its last-twelve-month revenue and 53x its last-twelve-month free cash flow.
Channel and Enterprise Impact
Once finalized, the combined entity will protect over 16,000 enterprise customers and millions of businesses worldwide, ranking among the largest pure-play data and AI cybersecurity operations globally. For the IT channel, managed service providers, and regional enterprise buyers, the merger directly addresses the operational friction of deploying disparate point solutions.
The combined roadmap centers on a unified platform that identifies sensitive enterprise data, enforces access permissions across both human personnel and automated AI agents, and mitigates exfiltration risks. Following transaction close, Proofpoint plans rapid alignment of both organizations’ go-to-market strategies, partner programs, and integrated platform delivery.
“Today begins an exciting new chapter for Varonis and our customers. It’s a testament to the incredible work of the Varonis team over two decades,” said Yaki Faitelson, Varonis CEO, Co-Founder and Chairman of the Board of Directors. “Our mission is to secure AI and the data that powers it. By joining forces with Proofpoint, we can achieve this mission faster than ever.”
Faitelson added, “This announcement follows a comprehensive evaluation led by a committee of independent members of our Board of Directors, which included extensive outreach to a range of potential strategic and financial buyers. This transaction is an excellent outcome for the company and our shareholders, representing a realization of immediate, significant, and certain value well in excess of the risk-adjusted value of delivering against our standalone plan.”
“As AI becomes embedded across the enterprise, the data it can access determines both its value and its risk. AI agents are increasingly accessing sensitive information and taking action across systems, making it critical for organizations to understand not only what data needs protecting and who can access it, but how it is actually being used,” said Sumit Dhawan, CEO of Proofpoint. “By connecting communications, identities, permissions, data, and AI, we are creating an intelligence advantage that helps customers see risk more clearly, respond faster, and defend against the next generation of AI risks. This is a defining step in Proofpoint’s evolution into a cybersecurity platform built for the future of AI.”
