CentraSite is installed with one predefined organization called Default Organization. The default organization owns the system-defined registry objects that CentraSite uses. You cannot delete the Default Organization, nor can you rename it.

As a best practice, you should avoid using the default organization as an ordinary organization. Instead, treat it as the home for system-wide objects such as asset types, taxonomies, targets and system-wide policies, and restrict membership in this organization to a small number of administrative users.
