Microsoft Copilot (Microsoft 365): Larger file upload support in Copilot Studio agent builder

🚨 The Signal: Copilot Studio now supports larger file uploads (up to 512 MB) for agent builders. This increases the potential volume of data that can be ingested by AI agents, impacting data governance and potential for sensitive information exposure.

The Impact

Security teams and data owners are affected by increased data exposure risk within Copilot agents.

• Security Teams: Increased risk of sensitive data exposure via AI agents.
• Data Owners: Greater responsibility for classifying and protecting data used in Copilot Studio.
• Compliance Officers: New considerations for data residency and regulatory compliance with larger data sets.
• AI Developers: Must ensure data used for agent training adheres to data handling policies.

The Action

1. Review and update data classification policies for content ingested by AI agents.
2. Implement data loss prevention (DLP) policies to prevent sensitive data upload to Copilot Studio.
3. Audit existing Copilot Studio agents for data sources and access permissions.
4. Educate Copilot Studio users on responsible data handling and sensitive information avoidance.
