Proofpoint has entered into a definitive agreement to acquire data security company Varonis Systems for approximately $6.3 billion. Upon the transaction's expected close in the first half of 2027, Varonis will become a private company and cease trading on the Nasdaq.
Why it matters
The acquisition combines Proofpoint's security stack with Varonis's data protection capabilities to create a unified platform aimed at defending against AI-accelerated threats. This consolidation reflects an industry-wide move to integrate data-centric security into broader enterprise threat management workflows.
The transaction is valued at an LTM Free Cash Flow multiple of 53x and an LTM Revenue multiple of 8.4x. The combined entity will serve more than 16,000 enterprise customers.
