Proofpoint bets $6.3bn on Varonis as AI agents drive data risks

Proofpoint is investing $6.3 billion to acquire Varonis Systems, a Miami-based cybersecurity company, in a bid to enhance its defense against AI-driven security threats. The all-cash deal sees Varonis shareholders receive $49.75 per share, marking a 52% premium over the company's last closing share price before rumors of a sale surfaced. Varonis offers a data security platform that grants organizations automated control over their critical data, and it positions itself as a company safeguarding AI and its supporting data.

Proofpoint, which was previously acquired by Thoma Bravo in 2021, is set to be taken private as well once the transaction closes. The combined entity will eliminate its presence on the Nasdaq. Thoma Bravo is providing equity financing, while debt financing commitments are in place to fund the purchase. Ontario Teachers’ Pension Plan will also join Proofpoint in the investment.

Following the merger, Proofpoint aims to quickly integrate Varonis's capabilities and align their go-to-market strategies. The new cybersecurity powerhouse will serve over 16,000 enterprises. Sumit Dhawan, CEO of Proofpoint, explained that AI agents access sensitive information and act across systems, making it crucial for organizations to comprehend not only what data requires protection and who can access it, but also how it is being utilized.

By integrating communications, identities, permissions, data, and AI, Proofpoint aims to deliver an intelligence advantage to customers, enabling them to identify risks more clearly, respond faster, and defend against emerging AI threats.

Yaki Faitelson, co-founder, CEO, and chair of Varonis, expressed enthusiasm about the partnership, stating, "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." The Varonis board has unanimously approved the transaction, which is expected to conclude in the first half of 2027, pending shareholder approval and regulatory clearances. In the interim, Proofpoint and Varonis will continue to operate independently.
