CACI NSS, LLC

CACI NSS, LLC specializes in mission-critical information technology operations, systems design, and sustained IT support services for federal agencies. Their core capabilities center on end-to-end IT modernization, including system design, maintenance, and operational support for complex government environments. They deliver managed services for enterprise platforms such as ServiceNow and Assured Compliance Assessment Solution (ACAS), with deep expertise in IT operations and maintenance, help desk support, network infrastructure assessment, and accounting system sustainment. Their technical proficiency spans cybersecurity compliance, application lifecycle management, and infrastructure optimization, with a focus on delivering resilient, scalable solutions aligned with federal IT standards and efficiency mandates. A key differentiator is their ability to rapidly deploy and sustain mission-aligned IT systems under strict operational constraints, particularly in high-demand environments like CISA and DOJ. The contractor maintains strong, recurring relationships with the Department of Homeland Security, particularly supporting CISA’s Office of the Chief Information Officer through IT operations, help desk services, and compliance-driven initiatives. They also provide sustained IT support to the Department of Justice, Department of Agriculture, and Department of Defense, often managing legacy systems, modernizing accounting platforms like HUDCAPS, and implementing compliance tools. Their engagement pattern reflects long-term, task-order-based partnerships focused on operational continuity and efficiency. Their primary focus is on Other Computer Related Services and Computer Systems Design Services, reflecting a specialization in delivering tailored IT solutions rather than off-the-shelf products. They serve verticals requiring high reliability—law enforcement, agricultural data systems, housing finance, and defense compliance—positioning them as a trusted provider for mission-essential IT sustainment. CACI NSS, LLC is a 2L entity headquartered in Chantilly, Virginia, with a focused presence in the federal IT services market. While no certifications are listed, their consistent award history demonstrates proven capability in delivering complex, compliance-sensitive IT services to federal clients.
