- A Slack user account
- Membership in a Slack Workspace (Free, Pro, Business+, or Enterprise Grid)
- If you are not the Workspace Owner and the
Require App Approval setting is enabled for the Workspace, request permission to install apps.
For the Slack integration to function, Cloudflare CASB requires the following Slack API permissions:
These permissions follow the principle of least privilege to ensure that only the minimum required access is granted. To learn more about each permission, refer to the Slack Permission scopes reference.
The Slack integration currently scans for the following findings, or security risks. Findings are grouped by category and then ordered by severity level.
