Limit access to a specific Share Point
We have a 3rd party Cloud application (3PA) that is accessing Share Point content through the use of Delegated Access to Share Point. This means that technically 3PA can access all SharePoint sites...
Applications using the delegate permissions model only have access to sites that the user in whose context you are running the app does. So the way to control access would be to limit the permissions granted on the user.
Applications using the application permissions model get unrestricted access by default. For that scenario, you can use the Sites.Selected permission as detailed here: https://devblogs.microsoft.com/microsoft365dev/controlling-app-access-on-specific-sharepoint-site-collections/
