Sentinel Secure Build delivers permanent, temporary, modular, and containerized SCIFs designed and constructed in accordance with ICD/ICS 705 requirements. All solutions are tailored to the mission, threat environment, and risk determination established by the Accrediting Official (AO), with coordination across the CSA and CTTA as required.

 

RF Shielding / TEMPEST

Sentinel Secure Build integrates RF shielding and TEMPEST countermeasures to prevent compromising emanations. Systems may include continuous conductive barriers, shielded penetrations, filtered power and data pathways, and grounding solutions designed to support validation testing and accreditation.

 

Acoustic Protection

SCIF construction must ensure conversations within the secure space are unintelligible or inaudible outside the secure perimeter. Sentinel Secure Build implements assemblies designed to meet applicable Sound Group 3 or Sound Group 4 criteria through layered wall systems, acoustic insulation, and fully sealed doors, HVAC pathways, and penetrations.

Secure Penetrations & Access Points

All doors, HVAC ducting, and electrical or data penetrations are constructed to maintain the physical, acoustic, and RF integrity of the SCIF perimeter, ensuring no unintended pathways for sound, signal leakage, or physical compromise.

 

Accreditation Support

​

Sentinel Secure Build supports the full accreditation lifecycle—from design coordination through construction, testing, and closeout—helping clients achieve approval efficiently while minimizing rework, risk, and schedule impact.
