On June 3, 2020, ISOO issued CUI Notice 2020-02, Alternative Marking Methods. This notice provides agencies with additional marking guidance for when it is impractical to individually mark CUI due to its quantity, the nature of the information, or when the agency has issued a limited CUI marking waiver.
You can find all the CUI Notices here.
Does this approach also apply to DoD contractors that have CUI called out in the contract? Or does this only apply to Executive Branch Agencies?
