If we detect specific security threats related to an API integration in your account, we automatically revoke the client secret for the installed package. For example, if we detect that a client secret is exposed in a public repository, we revoke it, notify admins by email, and display a notification message in Marketing Cloud Engagement. If a follow-up security review determines that the secret isn’t compromised, we automatically restore it. This feature is enabled by default. Admins can’t turn it off.
Where: This change applies to all Marketing Cloud Engagement editions.
