Your client notices that users are creating workspaces outside of the Enterprise Grid org. What should you recommend your client do to prevent…

To prevent users from creating new, unmanaged Slack workspaces with a company email address, the organization's administrators must claim their email domain(s). This feature, available on the Enterprise Grid plan, centralizes administration by redirecting any new workspace sign-ups using a claimed domain into the official Grid organization. This ensures all company-related Slack activity occurs within the managed, secure environment, preventing data fragmentation and shadow IT. This is a direct, preventative technical control that solves the client's problem.

A. Relying on user communication/policy: This is not a technical preventative measure and is easily ignored by users, making it an unreliable solution for governance.

B. Implementing Single Sign-On (SSO): SSO controls authentication and access to the existing Grid, but it does not prevent a user from creating a new, separate workspace.

C. Deactivating users reactively: This is a reactive measure taken after the policy violation has already occurred, rather than preventing it from happening in the first place.
