Who is responsible for providing the NATO Facility Clearance Certificate?

The correct answer is the Defense Industrial Security Clearance Office (DISCO) because DISCO is the entity responsible for adjudicating security clearances for contractors and their facilities within the United States, including those that work with NATO. DISCO issues the NATO Facility Clearance Certificate after it has verified that a facility meets the necessary security requirements to handle classified information pertaining to NATO operations and projects. This involvement ensures that U.S. contractors are appropriately cleared to engage in defense contracts with NATO members.

While other organizations have roles in the security clearance process, only DISCO specifically handles the issuance of the NATO Facility Clearance Certificate in the context of U.S. contractors and NATO collaborations. The Department of Defense oversees security policy but does not directly issue facility clearances. A NATO command or the requesting NATO agency can make requests or verify the need for clearances, but they do not perform the adjudication or issuance of the certificates themselves.
