How Defender for Cloud Apps helps protect your Box environment
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.

Connect Box to Microsoft Defender for Cloud Apps
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.
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.
Sign into your Box account as an Admin user.
Go to the custom app settings. For more information, see Managing custom apps – Box Support
If your settings are configured to disable unpublished apps by default, enter the Defender for Cloud Apps API key for your data center, as listed in the following table, and save your changes.

Your data center details are shown in the Defender for Cloud Apps About page in the Settings area. For more information, see View your data center.
In the Microsoft Defender Portal, select Settings. Then choose Cloud Apps. Under Connected apps, select App Connectors.
In the App connectors page, select +Connect an app, and then select Box.
In the Instance name page, enter a name for the connection. Then select Next.
In the Follow the link pop-up, select Connect Box.
The Box sign-in page opens. Enter your credentials to allow Defender for Cloud Apps access to your team's Box app.
Box asks you if you want to allow Defender for Cloud Apps access to your team information, activity log, and perform activities as a team member. To proceed, select Allow.
Back in the Microsoft Defender Portal, you should receive a message saying that Box was successfully connected.
In the Microsoft Defender Portal, select Settings. Then choose Cloud Apps. Under Connected apps, select App Connectors. Make sure the status of the connected App Connector is Connected.
After connecting Box:
- You'll receive events for the 7 days prior to connection.
- 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.
If you have any problems connecting the app, see Troubleshooting App Connectors.
