Word: Choose the level of detail for summaries when documents are opened

🚨 The Signal: Copilot in Word now allows users to choose summary detail levels (brief, standard, detailed) when opening documents. This impacts how much information Copilot extracts and presents, potentially affecting data exposure and information governance.

The Impact

End users can now control Copilot summary detail, increasing the risk of over-summarisation or excessive detail exposure.

• End Users: May inadvertently expose sensitive data through detailed summaries or miss critical context with brief summaries.
• Security Teams: Need to understand how summarisation levels affect data handling and potential information leakage.
• Compliance Teams: Must assess if varying summary details align with data retention and disclosure policies.

The Action

1. Review existing Copilot governance policies for document interaction and summarisation.
2. Communicate best practices to end-users regarding appropriate summary detail selection for different document sensitivities.
3. Monitor Copilot usage and summarisation patterns for potential data handling anomalies.
4. Consider implementing Microsoft Purview Data Loss Prevention (DLP) policies to detect sensitive information in Copilot outputs.
