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.
App connectors use the APIs of app providers to enable greater visibility and control by Microsoft Defender for Cloud Apps over the apps you connect to.
Microsoft Defender for Cloud Apps leverages the APIs provided by the cloud provider. All communication between Defender for Cloud Apps and connected apps is encrypted using HTTPS. Each service has its own framework and API limitations such as throttling, API limits, dynamic time-shifting API windows, and others. Microsoft Defender for Cloud Apps worked with the services to optimize the usage of the APIs and to provide the best performance. Taking into account different limitations services impose on the APIs, the Defender for Cloud Apps engines use the allowed capacity. Some operations, such as scanning all files in the tenant, require numerous APIs so they're spread over a longer period. Expect some policies to run for several hours or several days.
Defender for Cloud Apps supports multiple instances of the same connected app. For example, if you have more than one instance of Salesforce (one for sales, one for marketing) you can connect both to Defender for Cloud Apps. You can manage the different instances from the same console to create granular policies and deeper investigation. This support applies only to API connected apps, not to Cloud Discovered apps or Proxy connected apps.
Multi-instance is not supported for Office 365 and Azure.
How it works
Defender for Cloud Apps is deployed with system admin privileges to allow full access to all objects in your environment.
The App Connector flow is as follows:
Defender for Cloud Apps scans and saves authentication permissions.
Defender for Cloud Apps requests the user list. The first time the request is done, it may take some time until the scan completes. After the user scan is over, Defender for Cloud Apps moves on to activities and files. As soon as the scan starts, some activities will be available in Defender for Cloud Apps.
After completion of the user request, Defender for Cloud Apps periodically scans users, groups, activities, and files. All activities will be available after the first full scan.
This connection may take some time depending on the size of the tenant, the number of users, and the size and number of files that need to be scanned.
Depending on the app to which you're connecting, API connection enables the following items:
- Account information - Visibility into users, accounts, profile information, status (suspended, active, disabled) groups, and privileges.
- Audit trail - Visibility into user activities, admin activities, sign-in activities.
- Account governance - Ability to suspend users, revoke passwords, etc.
- App permissions - Visibility into issued tokens and their permissions.
- App permission governance - Ability to remove tokens.
- Data scan - Scanning of unstructured data using two processes -periodically (every 12 hours) and in real-time scan (triggered each time a change is detected).
- Data governance - Ability to quarantine files, including files in trash, and overwrite files.
The following tables list, per cloud app, which abilities are supported with App connectors:
Since not all app connectors support all abilities, some rows may be empty.

Defender for Cloud Apps is deployed in Azure and fully integrated with ExpressRoute. All interactions with the Defender for Cloud Apps apps and traffic sent to Defender for Cloud Apps, including upload of discovery logs, is routed via ExpressRoute for improved latency, performance, and security.

Disable app connectors
- Before disabling an app connector, make sure you have the connection details available as you will need them if you want to re-enable the connector.
- Once an Azure connector is disabled, it can't be re-enabled. If the connector is disabled by accident, contact Microsoft support.
- These steps cannot be used to disable Conditional Access App Control apps and Security configuration apps.
To disable connected apps:
- In the Connected apps page, in the relevant row, click the three dots and select Disable App connector.
- In the pop-up, click Disable App connector instance to confirm the action.
Once disabled, the connector instance will stop consuming data from the connector.
Re-enable app connectors
To re-enable connected apps:
- In the Connected apps page, in the relevant row, click the three dots and select Edit app. This starts the process to add a connector.
- Add the connector using the steps in the relevant API connector guide. For example, if you are re-enabling GitHub, use the steps in Connect GitHub Enterprise Cloud to Defender for Cloud Apps.
