What the 15 October 2026 agreement says, why an email-security company wants a file-permissions company, and what an Indian Varonis or Proofpoint customer should ask before the H1 2027 close.
Proofpoint will pay $49.75 a share in cash for Varonis, about $6.3 billion and a 52% premium to the $32.71 at which Varonis closed on 22 June 2026, the last full trading day before the sale rumours began.1 The agreement was signed on 15 October 2026 and approved unanimously by the Varonis board; Thoma Bravo, which owns Proofpoint, is providing the equity with Ontario Teachers’ Pension Plan investing alongside; the close is expected in the first half of 2027.1 It is the largest cybersecurity acquisition announced so far this year,3 and an odd one on its face: an email-security company is buying a company whose core product, since 2005, has been a map of who can open which file.9 The price says why.
Classic DLP, Proofpoint’s second business after email, watches the exits. It sits on the mail gateway, the browser upload and the USB port and pattern-matches content on the way out: a PAN, a card number, a file stamped confidential. It fails when the problem is not the exit but the entitlement. A SharePoint site open to “Everyone” or a file share nobody has reviewed in years is not a loss event, so nothing fires. Varonis sells the other half: it computes effective access, through nested groups, inherited rights and share links, to every piece of data it classifies, then removes the access nobody uses. The trade calls the first part DSPM and the second Data Access Governance.9
Copilots and agents turned that from a hygiene project into the binding constraint. An assistant will surface anything its user can read, so over-permissioning becomes a leak no content rule can describe. The regulated form of the question, where personal data lives and who can reach it, is what the DPDP Rules on breach reporting and erasure ask from 13 May 2027.7 Proofpoint already owns a DSPM, Normalyze, and an India data centre opened in 2025.8 It is paying 8.4 times Varonis’s trailing revenue and 53 times its trailing free cash flow for the deeper version, and for the permission data of 16,000 enterprises to sit beside its own email and identity telemetry.1
Three 2026 transactions set the scale. Google completed Wiz at $32 billion on 11 March;4 Palo Alto Networks completed CyberArk at $25 billion in February;5 Visa agreed to buy BioCatch for $2.4 billion on 3 August.6 Varonis is the only one of the four bought by a private-equity-owned company, and private equity does not pay 52% over the undisturbed price for a product it admires. It pays because the combined company removes a vendor and a dataset from the customer’s stack; the pricing power that follows is what a 53-times-cash-flow multiple assumes.1

Nothing changes contractually until the deal closes, and Proofpoint says product plans will be shared only after that.2 The next six to eight months are therefore when an Indian customer of either company has the most room to negotiate.
