Entra ID Enables Blocking for Nested Security Groups

A new Entra ID feature enables the ability to block nesting for security groups. In other words, you can’t include other groups as members of a group. That might not sound important, but it is to those who manage permissions, especially when the time comes to figure out who exactly has access to something confidential. The new feature isn’t fully implemented yet, but it should be very valuable when it’s fully deployed to tenants.
