The concept of limiting external sharing in SharePoint is essential for safeguarding your organization's data and maintaining security.
External sharing refers to the practice of allowing individuals who are outside of your organization and not part of the same tenant (or not federated with your domain) to access and collaborate on your SharePoint files and sites. A typical scenario involves teams like sales collaborating with external vendors or contractors by sharing files. These external vendors and contractors are classified as external users.

It's a practical and effective strategy to maintain control over external sharing in SharePoint.
