We are using Jira SD and Confluence Cloud. Our clients are business users and our product is sensitive, so we would like to protect the documentations and limit the access to the knowledge base articles. Our plan is to let Service Desk users (only approved ones) to see the articles and let them self service but we do not want it to be a public, free to access in the web. How can we configure it? Is there a way to approve a registration, or add a flag to and SD customer to have access to the knowledge base?
