HSU excels in designing and constructing Sensitive Compartmented Information Facilities (SCIFs). SCIFs vary in the level of security or information needed, and many of our clients require SCIFs to perform daily operations. SCIFs provide physical and technical elements to protect personnel and prevent electronic eavesdropping. We are experienced in designing and constructing SCIFs for specific environments—both domestically and internationally—that conform to DCID 6/9, ICD705, and other SCIF requirements.

Our expertise extends to the design and construction of specialized SCIFs, Special Access Program (SAP) Facilities, and Radio Frequency Shielded Enclosures (RFSE), all built to meet accreditation standards with precision.
