Defense Security Service

A Facility Security Clearance from the Defense Security Service (DSS) is a determination that cleared defense contractors are eligible for access to classified information at the same or lower classification category as the clearance being granted.

The very first step to clearing a company is for them to be sponsored for a facility clearance by either a government contracting activity (GCA) or another cleared company. Contractors requiring classified access should contact the DSS security office in their operating location.
