The contractor delivers end-to-end support for Physical Access Control Systems (PACS), including quarterly inspections, maintenance response, and repair services for high-security infrastructure.

Their technical expertise includes system diagnostics, compliance-driven facility hardening, and real-time response protocols aligned with federal security standards. A key differentiator is their ability to bridge technical system maintenance with human security operations, ensuring seamless integration of electronic access controls with on-the-ground personnel. The company maintains a strong presence with the Department of Defense, supporting both domestic and overseas security infrastructure requiring precise system upkeep and protective services. They also serve the Environmental Protection Agency with facility-specific PACS maintenance, indicating experience with civilian federal sites requiring stringent HSE compliance.

CHENEGA SENTINEL 360, LLC operates primarily under NAICS 561621 and 561612, focusing on non-locksmith security systems and armed/ unarmed patrol services. Their vertical specialization lies in federal facility protection, particularly where electronic access control systems intersect with physical security personnel. This positions them as a niche provider for agencies requiring hybrid security solutions that combine system integrity with human vigilance. As a limited liability entity based in Chantilly, Virginia, the company is structured for federal contract execution with no public certifications on record. Their geographic positioning in the National Capital Region supports proximity to key federal stakeholders and rapid deployment to high-priority sites across the U.S. and abroad.
