summary for non-techies**
Microsoft has updated its Purview Data Loss Prevention system to enhance security in the Edge for Business browser by extending protection to include file uploads, allowing the system to check file size, type, and sensitivity when uploaded to unmanaged generative AI apps, and block or audit uploads that don't meet security policies.
