We build different GDPR tools to help out the system administrator. In many associations, multiple projects have the same requirements regarding access rights. Our view permission feature prevent having to look up permissions individually for every project or user across the entire Confluence instance. Once a user has view access permission to a project, you will see it in this tool.
There are several ways to verify if someone has a certain permission. But the easiest and fastest one is to use the View Permission tool, if you want to know if a user have access to a project, for this.
You have the choice to filter by User or by Space
