Security Visits

The Security Office supports SDL in physical, personal, and classified security.

Security procedures followed by SDL include the use of picture identification and electronically coded badges to control access to our facilities. We also require visitors to sign the visitor’s register and to provide valid identification or proof of US citizenship.

Unclassified Visits

Unclassified visits are arranged through a point of contact at SDL. Visitors sign in at the front desk, where they receive temporary visitor badges. The receptionist notifies the SDL point of contact of the visitor’s arrival.

Classified Visits

All visitors attending a classified meeting at SDL facilities must submit a visit request as follows:


North Logan DISS SMO code 05924
Albuquerque DISS SMO code 4Z7J65
Huntsville DISS SMO code 90HZ3
Stafford DISS SMO code 8EX15

Please include technical POC and phone number

Upon check-in at SDL facilities, verification of a visitor’s approval to access classified information will take place.

U.S. or State Government issued photo ID will be required for facility admittance and issuance of a temporary visitor badge reflecting the appropriate level of clearance.

After such verification, the SDL point of contact will be notified of their visitor’s arrival.
