Proofpoint Introduces New Security Capabilities for the Agentic Workspace

AI agents have quickly moved from experiment to everyday reality. They’re now writing emails, managing data, and carrying out tasks alongside employees. But as their role expands, so do the risks - agents can be manipulated, mishandle information, or expose sensitive data. At its Protect 2025 conference, Proofpoint introduced new capabilities to secure this “agentic workspace,” where people and AI agents work side by side.

Agentic Workspace Requires a Different Security Model

Traditional data security tools like DSPM or DLP were not built for a world where autonomous agents can click, share, and act just like people. Tim Choi, Group Vice President of Product Marketing at Proofpoint, explained why the company is taking a broader approach.

“What makes our approach to securing people and AI agents unique is our breadth in technologies that understands what’s in the content, the behavior around the content, and also the context of all that is taking place,” Choi said. “That allows us to have great fidelity when it comes to understanding a data exfiltration event. This core fidelity can be applied to humans and also agents. As such, when an agent is mishandling data, we’re able to provide greater accuracy that something has happened.”

By combining insights from content, behavior, and context, Proofpoint can extend the same level of protection to both people and AI agents - an area where point solutions often fall short.

Proofpoint announced four innovations to tackle these challenges:

  • AI exploit detection over email blocks malicious prompts before they reach inboxes, reducing the chance of corrupted AI outputs.
  • Data Security Complete consolidates discovery, classification, lineage, insider threat detection, and remediation into a single platform. It helps organizations understand where sensitive data lives, who touches it, and how it moves.
  • AI Data Governance adds controls for sanctioned and unsanctioned AI use, with policy enforcement to prevent data loss and privacy violations.
  • Secure Agent Gateway, built on the Model Context Protocol (MCP), monitors AI agent activity and applies guardrails to control access, redact sensitive data, and enforce compliance.

Tackling the Governance Gap

The growth of sanctioned and unsanctioned AI tools has also opened new blind spots for enterprises. Without proper oversight, sensitive data can flow into applications beyond IT’s control. Choi pointed to visibility and remediation as the two biggest hurdles.

“In the last six months we saw a four times increase in AI-assisted applications installed into cloud environments to help end users perform their work. This begs the question, ‘Do you have the visibility to see what data mishandling is taking place, through approved or sanctioned applications like Copilot or ChatGPT - or unsanctioned applications that a user may self-select and install without company approval?’”

Proofpoint’s AI Data Governance aims to close that gap.

'What Proofpoint AI Data Governance does is exactly what is needed by first off bringing that visibility to life. We are able to monitor and see the prompts, understand the intent behind the prompts, and stop any data from being revealed unintentionally. We’re able to remove these third-party applications that should not be within the environment - applications that have access to the data within your company,” Choi said.

For enterprises, this means having policy-driven oversight that can govern both approved and rogue AI tools without slowing the pace of work.

Enabling Service Providers to Deliver Agentic Workspace Security

MSSPs and channel partners play a key role in how enterprises adopt new technology. With Proofpoint’s Secure Agent Gateway and Satori Agents, providers can now extend their offerings into agentic workspace security.

“As MSSPs and service providers are working together with their customers to deploy and build out a customer’s agentic workspace with new agents that perform the work, Proofpoint AI Data Governance and Proofpoint Secure Agent Gateway could be an easy add-on or integrated solution to provide additional security to these agents,” Choi said.

This creates opportunities for partners to differentiate by delivering managed services that secure not just people and data, but also the agents driving new workflows.
