The Corporate Proprietary standard security label is used to indicate an object's level of corporate sensitivity.

While security labels themselves have no hierarchy, this effect can be achieved by nesting the authorized participant groups. The Highly Trusted Employees group is a member of the Internal Personnel group, which in turn is a member of the Employees group. If they have the appropriate access control permissions, members of the Highly Trusted Employees group can then access objects marked with the Private, Internal, or Company Most Private label values. Members of the Internal Personnel group can access objects marked as Private or Internal, while members of the Employees group can access objects marked as Private. Users outside of these groups can be granted temporary access through use of a Non-Disclosure Agreement. The Non-Disclosure Agreement is a context-based agreement type because it is a subtype of the ContextBasedAgreement subtype.

Objects marked as Public (the null value) are unrestricted and can be accessed by anyone with the necessary permissions on the object.
