Proofpoint, Inc., a global leader in cybersecurity and compliance, has announced the acquisition of Acuvity, a company recognized for its pioneering work in AI enterprise security and governance. With this move, Proofpoint significantly expands its platform by adding AI-native visibility, governance, and runtime protection designed specifically for AI-powered and agent-driven workflows.

As generative AI continues to transform the workplace, organizations are rapidly integrating AI copilots, autonomous agents, and connected applications across departments such as software development, customer service, finance, and legal operations. While these tools bring impressive gains in productivity and innovation, they also create entirely new categories of risks. For example, businesses now face challenges like shadow AI usage, exposure of sensitive data, intellectual property loss, compliance violations, and AI-focused threats such as prompt injection and model manipulation.

Securing AI in the Agentic Workspace

Through this acquisition, Proofpoint enhances its human- and agent-centric security platform to provide stronger governance, visibility, and control within the growing “agentic workspace.” This is the environment where humans and AI agents increasingly collaborate to perform business-critical tasks. By integrating Acuvity’s AI-native security capabilities, enterprises can adopt generative AI with greater confidence, ensuring that innovation does not compromise compliance, trust, or security.

“AI agents are becoming active participants in the enterprise, accessing data, executing tasks and making decisions alongside people. Securing this new model of work requires understanding human intent, agentic behavior and risk in real time,” said Ryan Kalember, Chief Strategy Officer, Proofpoint. “Together, Proofpoint and Acuvity enable organizations to confidently adopt AI tools and agents with the governance, visibility and control required to manage risk. By securing humans, defending data and governing AI through a unified platform, Proofpoint is uniquely positioned to protect the agentic workspace end to end something no other cybersecurity company delivers today.”

A Unified Platform for People, Data, and AI

Acuvity adds critical control points and detection models built specifically for the AI era. Its platform delivers enforcement and visibility across enterprise AI usage, covering everything from endpoints and browsers to emerging AI infrastructure such as Model Context Protocol (MCP) servers. Additionally, it supports governance of locally installed AI tools like OpenClaw and Ollama.

Moreover, Acuvity’s AI-powered detection models understand context and intent, helping organizations secure interactions with external AI services while also protecting custom AI applications and models deployed internally.

With these capabilities, Proofpoint positions itself as the first unified platform to secure every dimension of the agentic workspace. The combined portfolio strengthens Proofpoint’s leadership among CISOs and CIOs by offering integrated solutions across:

  • Collaboration Security to protect employees from human-centric threats
  • Data Security and Governance to safeguard sensitive information wherever it resides
  • AI Security to manage enterprise AI adoption and protect AI applications and models

“AI is fundamentally reshaping how work gets done and enterprises are overwhelmed by the pace of AI adoption and the complexity of securing it,” said Satyam Sinha, co-founder and CEO, Acuvity. “In an AI-accelerated world, intelligence is no longer confined to applications or infrastructure; it lives in interactions, decisions and autonomous agents acting on our behalf. Securing that future requires a new approach one that governs how AI thinks, acts and learns in real time.”

Ultimately, Acuvity’s technology is expected to further strengthen Proofpoint’s ability to secure how people and AI agents communicate, collaborate, and interact with critical business data. This acquisition reflects Proofpoint’s commitment to helping enterprises embrace AI innovation securely and responsibly.
