LRAFB SFPC Safeguarding Classified Information in the NISP Practice Test

Grandfathering is the key idea here: a pre-existing practice can continue even when new rules would change the landscape. In this case, only companies that were already using guards before the 1995 cutoff were allowed to keep using them for open storage areas. That’s why this statement is true—guard usage isn’t open to every company, and it isn’t universally prohibited or mandatory. For those that didn’t have guards before 1995, the policy would steer them toward other safeguards or updated requirements rather than extending the old arrangement.
