Thoma Bravo-backed Proofpoint Inc. reached a deal to buy Varonis Systems Inc. for roughly $6.3 billion. The agreement values Varonis at a 52% premium to its June 22 close, the last trading day before rumors of a potential transaction surfaced.
Proofpoint focuses on stopping threats like phishing, malicious emails and other cyber risks. Varonis helps companies watch and control access to data on cloud systems.
Boro added that Thoma Bravo expects Varonis to keep expanding. "We see a lot of opportunity to continue to innovate," he said, adding, "This AI buildout is really only possible with this foundational cyber layer."

Attention to AI security has surged over the past few weeks, spurred by reports of AI agents acting in concert on their own, fueling worries that companies could lose control of the technology. That backdrop frames Boro's view that guardrails are not a nice-to-have but a prerequisite for AI deployment.
The lens for investors is straightforward: Boro links AI growth to a base layer of cybersecurity, and the pending Proofpoint-Varonis deal puts that theme in focus. Companies that protect email, data and access look positioned as AI adoption ramps, if that foundational layer proves as essential as Boro says.
