This is a complete facility with conference rooms, a full-size break room, a large IT room with separate air conditioning, and SCIF space available The existing SCIF has not been active as of April 2024 and it was built on 705 SCIF standard. It has two sections. The small room is DCSA-certified for Secret Storage, and the rest of the space was once accredited as a SCIF by the NSA. That was in 2015, and it hasn’t been used since. So, it’s no longer active or accredited. It could be brought back into compliance, but the standards have changed since then. The total space is 891 square feet.
