Sentar, Inc.

Sentar, Inc. is a woman-owned small business headquartered in Huntsville, Alabama, that specializes in providing comprehensive cybersecurity, information technology, engineering services, and technical support to federal defense and civilian agencies. Registered in SAM.gov since February 2002, Sentar operates as a for-profit Subchapter S Corporation and has established itself as a significant player in the federal contracting landscape, particularly within the Department of Defense. The company's expertise spans systems engineering, software development, cybersecurity operations, risk management, and mission-critical technical solutions across multiple defense and federal entities.

Through its prime federal contract awards, Sentar has demonstrated substantial capability in delivering complex technical services across the defense sector. The company has received multiple Small Business Innovation Research (SBIR) Phase I contracts, including a $239,984 award from Naval Strategic Systems Programs (July 2025) for advanced naval strategic systems research and a $99,995 contract from the Defense Logistics Agency for "Zero Trust for Digital Twins" technology development. Beyond SBIR programs, Sentar has secured significant delivery orders under various indefinite delivery vehicles, including a substantial $172.76 million cost-plus-fixed-fee delivery order from the Defense Health Agency for cybersecurity risk management and operations support through May 2029, and an $18.1 million delivery order from Army Contracting Command Redstone for Enterprise Resource Planning services supporting Air Mobility Command through February 2029. Additional noteworthy prime contracts include a $5.35 million delivery order under the ITES-3S vehicle for functional services and support at Huntsville through September 2028, and multiple delivery orders under the Pacific Communications Division Technical and Engineering Support IDIQ from Naval Information Warfare Systems Command, totaling over $1.2 million for engineering services. The company has also provided software subscription services through firm-fixed-price purchase orders to the Naval Observatory and Office of Naval Research for CODE VALOR subscriptions. Regarding subcontract work, Sentar regularly partners with major defense contractors including KBR Wyle Services, Booz Allen Hamilton, Amentum Technology, Teledyne Brown Engineering, and others to provide engineering services, cybersecurity support, computer systems design, and labor services on programs supporting various Department of Defense initiatives, National Security Agency requirements, and Navy information systems modernization efforts.

Sentar's federal grant activity has been more limited compared to its contract portfolio. The company was awarded a $199,885 project grant from the Department of Energy Office of Science in July 2023 under the Office of Science Financial Assistance Program (CFDA 81.049) for research and development related to "THREATHELM: Enhanced Cyber Resiliency," a one-year effort concluding in July 2024. This grant focused on enhancing cyber resiliency and real-time application security, directly aligning with Sentar's core cybersecurity competencies and supporting DOE's mission to advance scientific discoveries that enhance national security.

Sentar maintains multiple active indefinite delivery indefinite quantity (IDIQ) contract vehicles that position it to compete for task orders across federal agencies. Most significantly, the company was recently awarded positions on the OASIS+ Total Small Business Set-Aside IDIQ (December 2024, ceiling $999.999 billion through December 2029) and the OASIS+ Unrestricted IDIQ (December 2024, ceiling $999.999 billion through December 2029), both administered by the General Services Administration's Federal Acquisition Service, enabling Sentar to compete for professional services task orders across seven functional domains including management and advisory, technical and engineering, research and development, and intelligence services. The company also holds the EMERGENT IV BAA0001-22 single-award IDIQ (September 2025, $50 million ceiling through September 2030) awarded by Troop Support for Shield and Strike infrastructure initiatives. Within the Department of Navy, Sentar holds the Enterprise Personnel Systems Engineering (EPSE) multiple-award IDIQ (September 2021, $59.57 million ceiling through September 2031) for enterprise systems engineering and lifecycle support, the Pacific Communications Division Technical and Engineering Support multiple-award IDIQ (March 2021, $129.79 million ceiling through March 2027) for technical and engineering services supporting information warfare programs, the Engineering and Support Services for Network and Information Systems Technology Programs multiple-award IDIQ (July 2021, $68.04 million ceiling through July 2028), and the National Cyber Range Complex Event Planning, Operations and Support (NCRC EPOS) multiple-award IDIQ (July 2021, $2.42 billion potential value through July 2031) supporting Department of Defense cyber range capabilities. Additionally, Sentar maintains the Information Technology Enterprise Solutions 3 - Services (ITES-3S) vehicle under Army Contracting Command Redstone and holds a Woman-Owned Small Business set-aside Blanket Purchase Agreement with NASA Marshall Space Flight Center for ground systems engineering support services (expired June 2024). Task orders under these vehicles have ranged from housekeeping orders with nominal values to substantial awards exceeding $172 million, supporting diverse mission requirements across the Department of Defense, Army, Navy, Air Force, and civilian agencies including the Department of Energy and NASA.
