Proofpoint, a leading cybersecurity and compliance company, has announced Proofpoint AI Security, a new security solution that combines intent-based detection, multi-surface control points, and a comprehensive implementation framework to secure how humans and AI agents use AI across the enterprise. The solution is based on the industry-first Agent Integrity Framework, which defines how an AI agent should operate with integrity, and introduces a five-phase maturity model for implementation.

Why it matters

As organizations rapidly deploy autonomous AI agents to perform various tasks, there are growing risks such as agentic privilege escalation and zero-click prompt injection attacks. Existing security tools lack the ability to evaluate whether AI behavior aligns with the original user intent, highlighting the urgent need to secure agentic AI environments.

The details

Proofpoint AI Security applies intent-based detection models to continuously evaluate whether AI behavior, initiated by a human or an autonomous agent, aligns with the original request, defined policies, and intended purpose. The solution operates across the surfaces where AI is used, including endpoints, browser extensions, and MCP connections, providing organizations with the visibility and control needed over AI usage and risks. Proofpoint is also introducing the Agent Integrity Framework, a comprehensive guide that defines what it means for an AI agent to operate with integrity and provides a five-phase maturity model for implementation.
