Microsoft Copilot in Microsoft Purview

  • 10 minutes

Microsoft Copilot for Security is now accessible from within Microsoft Purview data security solutions, as part of the embedded experience. With Microsoft Copilot in Microsoft Purview, data security and compliance admins can use the power of AI to assess risk exposure more quickly than is otherwise possible, directly from within Microsoft Purview solutions.

The scenarios supported as part of the embedded experience are:

  • Gain comprehensive summary of Data Loss Prevention alerts.
  • Gain comprehensive summary of Insider Risk Management alerts.
  • Gain contextual summary of Communication Compliance policy matches.
  • Gain contextual summary of evidence collected in eDiscovery review sets (Preview).

For all use cases supported through the embedded experience, as is the case with the standalone experience, your organization must be onboarded to Microsoft Copilot for Security, the Purview plugin must be enabled in Copilot, and your organization must be licensed and onboarded to the applicable Microsoft Purview solutions. To enable the Microsoft Purview, the option to allow Copilot for Security to access data from your Microsoft 365 services must be enabled, as part of the owner settings.

Additionally, users must have the appropriate role permissions for both Copilot and the Purview solutions. For Copilot, users need, at a minimum, the Copilot workspace contributor role or the Entra Security operator role. For Microsoft Purview, as is true for a Microsoft solution enabled via a plugin, Copilot assumes the permissions of the user when it tries to access the data to answer the queries, so you need to have the required permissions to access the data.

Gain comprehensive summary of alerts

Data security teams generally receive more data security alerts per day than they can review, leaving them exposed to risks. To help with this challenge, Microsoft Copilot in Microsoft Purview uses the power of generative AI to provide a summary for the alert you want to review and help accelerate your investigation. This capability is supported in Microsoft Purview Data Loss Prevention and Microsoft Purview Insider Risk Management.

Data Loss Prevention

To summarize Data Loss Prevention alerts using Copilot:

  1. Sign in to the Microsoft Purview compliance portal, or the new Microsoft Purview portal currently in preview, and select the Data Loss Prevention solution.

  2. Navigate to the alerts queue and select the alert you want to review.

  3. Select "Get a summary from Security Copilot."

The ability to summarize Insider Risk Management alerts, enables you to quickly gain the highlights of the potential incident by identifying critical user details like exfiltration activities, patterns, user roles, and unusual activities that may lead to potential security incidents.

Gain contextual summary of content in a Communication Compliance policy

Reviewing communications is an integral part of protecting your organization’s communication landscape, but it's also time-consuming to review content that is hundreds of words long or contain attachments. With Copilot, you can now:

  • Get a contextual summary of a message and its attachments in the context of classifier conditions that flagged the message.
  • Ask follow-up contextual questions about the message and its attachments.

Contextual Summarization currently supports trainable classifiers as context and contextual summaries are only eligible for messages and attachments with a combined length of 100 words or more.

Before you get started, ensure you have proper licensing to access Communication Compliance and the appropriate role permissions for Copilot and Communication Compliance. To get contextual summaries in policies, you must have Communication Compliance or Communication Compliance Investigator Role. For Copilot, you need, as a minimum, the Entra Security operator or Copilot workspace contributor role.

To get started:

  1. Navigate to the Communication Compliance solution from the Microsoft Purview compliance portal, or the new Microsoft Purview portal currently in preview, then navigate to the Policies tab in Communication Compliance.

  2. Navigate to a policy that uses trainable classifiers as part of the policy’s configurations and select a policy match to view message content.

  3. A Copilot action button appears in the upper left command bar or a Summarize action button in the lower right command bar. Select either action to generate a contextual summary of the message and supported attachments.

  4. To learn more about the message, explore other default prompts or type your own question into the text prompt in the Security Copilot side panel.
