Note
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.
Slack is a cloud service that helps organizations collaborate and communicate in one place. Along with the benefits of effective collaboration in the cloud, your organization’s most critical assets may be exposed to threats. Exposed assets include messages, channels, and files with potentially sensitive information, collaboration, and partnership details, and more. Preventing exposure of this data requires continuous monitoring to prevent any malicious actors or security-unaware insiders from exfiltrating sensitive information.
Connecting Slack Enterprise (Grid or Select) to Defender for Cloud Apps gives you improved insights into your users’ activities and provides threat detection for anomalous behavior.
Main threats
- Compromised accounts and insider threats
- Data leakage
- Insufficient security awareness
- Unmanaged bring your own device (BYOD)
How Defender for Cloud Apps helps to protect your environment
- Detect cloud threats, compromised accounts, and malicious insiders
- Use the audit trail of activities for forensic investigations
Control Slack with policies

Automate governance controls
In addition to monitoring for potential threats, you can apply and automate the following Slack governance actions to remediate detected threats:
| Type | Action |
|---|---|
| User governance | Notify user on alert (via Azure AD) Require user to sign in again (via Azure AD) Suspend user (via Azure AD) |
For more information about remediating threats from apps, see Governing connected apps.
