Proofpoint, a cybersecurity and compliance company, completed the acquisition of Acuvity, a company specializing in AI security. Financial terms were not disclosed. “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. 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,” Ryan Kalember, Proofpoint Chief Strategy Officer.
