How Defender for Cloud Apps helps protect your Box environment
Article
As a cloud file storage and collaboration tool, Box enables your users to share their documents across your organization and partners in a streamlined and efficient way. Using Box may expose your sensitive data not only internally, but also to external collaborators, or even worse make it publicly available via a shared link. Such incidents can be caused by malicious actors, or by unaware employees.
Connecting Box to Defender for Cloud Apps gives you improved insights into your users' activities, provide threat detection using machine learning based anomaly detections, information protection detections such as detecting external information sharing, and enabling automated remediation controls.
Main threats

This section provides instructions for connecting Microsoft Defender for Cloud Apps to your existing Box account using the App Connector APIs. This connection gives you visibility into and control over Box use. For information about how Defender for Cloud Apps protects Box, see Protect Box.
Note
Deploying with an account that is not an Admin account leads to a failure in the API test and does not allow Defender for Cloud Apps to scan all of the files in Box. If this is a problem for you, you can deploy with a Co-Admin that has all of the privileges checked, but the API test will continue to fail and files owned by other admins in Box will not be scanned.
To connect Box to Defender for Cloud Apps:
If you restrict application permission access, follow this step. Otherwise, skip to step 2.

Defender for Cloud Apps will perform a full scan of all files. Depending on how many files and users you have, completing the full scan can take a while.
To enable near real-time scanning, files on which activities are detected are moved to the beginning of the scan queue. For example, a file that is edited, updated, or shared is scanned right away rather than waiting for the regular scan process. Near real-time scanning doesn't apply to files that aren't inherently modified. For example, files that are viewed, previewed, printed, or exported are scanned as part of the regularly scheduled scan.
