Note

Microsoft Defender for Cloud Apps (previously known as Microsoft Cloud App Security) is now part of Microsoft 365 Defender. The Microsoft 365 Defender portal allows security admins to perform their security tasks in one location. This will simplify workflows, and add the functionality of the other Microsoft 365 Defender services. Microsoft 365 Defender will be the home for monitoring and managing security across your Microsoft identities, data, devices, apps, and infrastructure. For more information about these changes, see Microsoft Defender for Cloud Apps in Microsoft 365 Defender.

This connection gives you visibility into and control over Dropbox use. For information about how Defender for Cloud Apps protects Dropbox, see Protect Dropbox.
