What is a collateral security clearance?
A collateral security clearance is a clearance with no special access authorizations (e.g., special accesses such as COMSEC or NATO). In other words, Top Secret, Secret, and Confidential are collateral security clearances. (Back to top) What is a security clearance with a “caveat?” A security clearance with a caveat is a collateral security clearance, such as Secret or Top Secret, plus a special access. In order to have the special access, the cleared individual usually receives a briefing related to the caveat. COMSEC and NATO are examples of caveats requiring a briefing prior to access.
