In the agentic workspace, data security is paramount. That’s because AI agents face similar risks as humans—from social and prompt engineering attacks to intentional or accidental disclosure of sensitive information. AI agents are only as secure as the data they have access to.
In recognition of the emerging data security risks associated with agentic AI, Proofpoint is launching Proofpoint Secure Agent Gateway (available Q1 2026), a purpose-built solution that secures sensitive information flowing into and out of every agentic workflow.
Figure 1. Proofpoint Secure Agent Gateway secures sensitive information in all your agentic workflows.
Proofpoint Secure Agent Gateway leverages the Model Context Protocol (MCP), an emerging open standard that’s designed to connect AI agents with external data in a secure, auditable manner. Proofpoint chose MCP for its granular policy controls and transparent enforcement. However, we’ll continue to track this evolving space as new AI security standards and protocols are developed.
Proofpoint’s solution supports all MCP-compliant agents, whether those are commercial offerings or custom agents developed in house. This ensures universal compatibility across your whole agentic AI ecosystem. Leading software companies, including Microsoft (with Copilot Studio), OpenAI (with ChatGPT and Agents SDK), Google (with Google Cloud databases and security operations tools), Amazon Web Services (with the Lambda and Bedrock services), and Salesforce (with Agentforce) are already deploying MCP-compliant agents in enterprise environments.
With Proofpoint Secure Agent Gateway, you can:
- Control access to sensitive data used by agents via Proofpoint’s Zen Agent Gateway
- Monitor agent activities and enforce policies for usage of sensitive data
- Block or redact sensitive data before it reaches humans or agents
- The Data Risk Map provides a consolidated, intuitive view of where sensitive data resides, how it’s moving, and who is accessing it
Unlike point products that address agentic AI risks only in isolation, Proofpoint Secure Agent Gateway unifies agent controls with comprehensive data security policies across your entire environment. This integration ensures that every data flow—whether accessed by an AI agent or a human—is protected by consistent discovery, classification, monitoring, and enforcement. For security teams, this eliminates blind spots and reduces operational complexity.
