Proofpoint, Inc. has announced the acquisition of Acuvity, a company recognized for its innovation in AI enterprise security and governance. Through this strategic move, Proofpoint strengthens its cybersecurity platform by adding AI-native visibility, governance, and runtime protection designed specifically for AI-driven and agent-based workflows. As organizations increasingly integrate generative AI into daily operations, security leaders must adapt quickly to manage emerging threats tied to these advanced technologies.
Today, enterprises are rapidly deploying AI copilots, autonomous agents, and AI-connected applications across departments such as software development, customer service, finance, and legal operations. Consequently, while these tools improve productivity and accelerate innovation, they also introduce new risks. For example, organizations now face challenges such as shadow AI usage, exposure of sensitive corporate data, intellectual property leakage, regulatory compliance risks, and sophisticated AI-focused threats like prompt injection and model manipulation attacks. Therefore, companies require more advanced security frameworks capable of monitoring both human and AI activity in real time.

With this acquisition, Proofpoint expands its security architecture to support what it calls the “agentic workspace,” where human employees and AI agents collaborate to complete business-critical tasks. As a result, Acuvity’s AI-native security technology enables organizations to adopt generative AI confidently while maintaining strong governance, compliance, and data protection standards.
“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.”
Furthermore, Acuvity introduces new AI-era control mechanisms and detection models designed specifically for modern enterprise environments. Its platform delivers full visibility across enterprise AI usage, including endpoints, browsers, and emerging AI infrastructure such as model communication servers and locally deployed AI tools. Additionally, Acuvity’s contextual AI detection models help organizations understand intent and usage patterns, enabling stronger governance over how employees and systems interact with external AI services. At the same time, it protects internally developed AI models and applications from misuse or compromise.

As a result of this integration, Proofpoint now offers a unified security platform covering three core areas: protecting people from social and human-centric cyber threats, securing sensitive enterprise data across environments, and governing AI usage across the organization. This unified approach helps security leaders reduce tool fragmentation while improving overall risk visibility.
“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 capabilities are expected to significantly enhance Proofpoint’s portfolio, particularly in securing interactions between people, AI agents, and enterprise data. Therefore, this acquisition positions Proofpoint to help organizations adopt AI securely while maintaining trust, compliance, and operational resilience in an increasingly AI-driven enterprise landscape.
