    Hi ethanchalmers,

     

    I am not currently aware of an additional purview tool to prevent the upload you're referencing, as you have taken the steps to implement Endpoint DLP and what sounds like Session Control policies in MDCA to prevent uploads through the browser, which are the blocking tools you can leverage, based on specific sensitivity.

     

    However, you can also leverage File Policies within MDCA to scan SPO/OD4B for any file labeled as Highly Confidential and then leverage Governance Actions to Quarantine the file, which would remove the file and place a .TXT placeholder file in it's spot, moving the original to a location that is defined within the File Policy. Here's an article on File Policies, if needed.
