+# Audit 'Everyone' and  'Everyone except external users' claim within a SharePoint site
+
+## Summary
+
+As part of Microsoft 365 Copilot readiness, you may want to find where "Everyone and "Everyone except external users" claims are granted permissions which is a cause of oversharing.
+
+This is an example where 'Everyone except external users' has been added to the SharePoint site visitors group.
