illusive networks

Proofpoint is an enterprise cybersecurity company that markets a platform for human- and AI-centric security across what it describes as the agentic workspace. Its portfolio is organized into three main areas: collaboration security, which targets attacks on people and AI agents across communication channels; data security, which provides visibility and control over storage, access, usage and movement of sensitive data, communications and AI interactions; and AI security, which covers discovery of AI apps, users, agents, MCP servers and external services, runtime policy enforcement over employee prompts and agent actions, and audit trails for boards and regulators.

Core product lines referenced on the company's site include email security and email fraud protection (Proofpoint Email Protection, Prime Threat Protection, API-based email protection with attack chain visibility), phishing defense and user awareness, and data loss prevention. The company also publishes research and guidance material such as the Data Security Landscape Report, the AI and Human Risk Landscape Report, and the Agent Integrity Framework, a maturity model for securing autonomous AI.
