Imagine you have a secure filing cabinet where you store sensitive documents, and you want to ensure that only certain people can access these documents. Microsoft Purview Data Loss Prevention (DLP) acts like a security guard for your digital documents, making sure that only authorized users can access or process sensitive information.

Now, Microsoft has extended this security feature to Microsoft 365 Copilot, which is like a smart assistant that helps you with tasks by processing information from your files. With this update, DLP policies can now detect sensitivity labels on your documents. These labels are like digital tags that indicate how sensitive a document is, similar to marking a physical file as "Confidential" or "Top Secret."

When Microsoft 365 Copilot tries to access or process a document with a sensitivity label, the DLP policies can step in and restrict access, just like a security guard stopping someone from entering a restricted area. This ensures that sensitive information is not inadvertently shared or processed by Copilot without proper authorization.

This change helps organizations maintain control over their sensitive data, ensuring that only the right people and tools have access to it, just like keeping a close watch on who can open that secure filing cabinet.
