In this interview from RSAC 2026, Sumit Dhawan, chief executive officer of Proofpoint, joins theCUBE's Dave Vellante to discuss how AI is extending the human attack surface and why intent-driven guardrails are the new imperative for enterprise security. Dhawan details the acquisition of Acuvity and the rapid launch of Proofpoint AI Security, a platform designed to protect AI agents from prompt-based exploitation the same way Proofpoint has long defended humans from social engineering. He explains why traditional semantic analysis falls short and how an ensemble of specialized language models detects malicious intent across trillions of messages.
The conversation also explores Proofpoint's approach to token economics, where Dhawan advocates for prioritizing adoption and experimentation over premature ROI measurement — encouraging employees across engineering, sales and support to embrace AI without restrictions. He unpacks why the "SaaS apocalypse" narrative unfairly paints all software companies with the same brush, arguing that cybersecurity providers with proprietary data and continuous threat intelligence enjoy a compounding network effect that widens their competitive moat over time. Dhawan also outlines his framework for enterprise security consolidation, identifying five emerging platform categories — endpoint and XDR, SOC automation, identity, network and SASE, and human plus AI behavior — where organizations are converging on fewer strategic partners rather than chasing a single-provider model. From defending against multi-step prompt attacks to redefining how enterprises structure their security stacks for the agentic era, he provides a practical roadmap for balancing rapid AI adoption with the guardrails needed to keep both humans and machines in check.

Sumit Dhawan, Proofpoint
In this RSAC 2026 interview, Sumit Dhawan of Proofpoint discusses emerging artificial intelligence-driven threats and Proofpoint's response, including the Acuvity acquisition and the launch of Proofpoint AI Security. Hosts Dave Vellante of theCUBE and Christoph Bertrand of theCUBE lead the conversation and draw on theCUBE Research to explore intent-based protection, language-model ensembles, continuous context engineering and strategies for protecting human and AI behavior.
Key takeaways include the need for intent-driven guardrails for AI and ongoing investment in threat intelligence. Dhawan explains that Proofpoint pairs continuous context engineering with global threat feeds and community reporting to detect evolving prompt-based attacks. They advise prioritizing adoption and experimentation over immediate return on investment measurement and argue that incumbency and a data advantage strengthen established security platforms. The segment highlights platform strategy, email security and insider risk within broader cybersecurity trends.
