Connect Dropbox to Microsoft Defender for Cloud Apps


We've renamed Microsoft Cloud App Security. It's now called Microsoft Defender for Cloud Apps. In the coming weeks, we'll update the screenshots and instructions here and in related pages. For more information about the change, see this announcement. To learn more about the recent renaming of Microsoft security services, see the Microsoft Ignite Security blog.

This article provides instructions for connecting Microsoft Defender for Cloud Apps to your existing Dropbox account using the connector APIs. This connection gives you visibility into and control over Dropbox use. For information about how Defender for Cloud Apps protects Dropbox, see Protect Dropbox.

Because Dropbox enables access to files from shared links without signing in, Defender for Cloud Apps registers these users as Unauthenticated users. If you see unauthenticated Dropbox users, it may indicate users who aren't from your organization, or they might be recognized users from within your organization who didn't sign in.
