ISI delivers IT modernization, transformation, and professional staffing services to U.S. federal civilian agencies and the Department of Defense, with marquee 24- and 18-year engagements driving IT modernization at the IRS and SEC respectively. The firm positions itself as a nationwide provider of high-tech professionals spanning data analytics, cybersecurity, systems integration, infrastructure management, and program management.

The company's portfolio is anchored by two named solutions: Rapid Cloud Migration, a service offering assisting federal agencies and DoD in transitioning legacy systems to cloud infrastructure, and the AI Continuous Assurance and Governance Framework (AICAF), a proprietary framework providing continuous assurance and governance for AI implementations in federal environments. ISI's go-to-market is entirely business-to-government, executing through federal contract vehicles and engaging federal buyers and prime contractors via enterprise field sales motions grounded in past performance and compliance credentials. Revenue is generated through professional services contracts awarded under standard federal acquisition processes, with pricing negotiated per task order rather than disclosed publicly.
