The company's technology centerpiece is Security Control, a cloud-based, FedRAMP Ready SaaS platform hosted in AWS GovCloud for facility and clearance management; it is reported to be in use by over 1,000 Facility Security Officers nationwide. ISI complements this SaaS with Facility Control (DCSA-ready facility clearance packages), SWFT Fingerprinting (electronic fingerprinting for security clearance processing), and CMMC Readiness & Implementation services that span gap assessments, documentation, policy creation, remediation, and ongoing compliance monitoring. ISI has achieved CMMC Level 2 Certificate of status and is a Registered Provider Organization with Cyber-AB.

ISI monetizes through a combination of recurring SaaS subscriptions, managed services (outsourced FSO programs, ongoing compliance monitoring), and project-based professional services (CMMC readiness, fingerprinting). Go-to-market is enterprise field sales targeting defense contractors from SMBs to large federal primes, supported by a content-led demand engine (blog, webinars, newsletters, interactive readiness questionnaires) and a Partner Referral channel program. Headquartered in Reston with an additional Herndon office, ISI reports serving over 900 defense contractors across aerospace, defense, manufacturing, and engineering. Leadership comprises CEO David Lawrence, President of IT & MSP Services Bryan Champagne, President of FSO & Clearance Services Cate Pearson, and VP of Compliance John Nolan.

Broad incumbents

• SAIC: Federal IT modernization and cybersecurity services contractor with significant DoD and intelligence community exposure. Provides compliance and security services to defense contractors as part of broader engagements.
• ManTech International: Federal technology services firm (now part of CGI Federal) specializing in cybersecurity and IT for DoD customers. Overlaps with ISI on managed IT and security for defense contractor environments.
• CACI International: Federal services and IT contractor serving DoD and intelligence customers with cybersecurity and mission-support solutions. Comparable in defense contractor customer base but with much broader service portfolio.
• Leidos: Large federal IT and cybersecurity services provider with deep DIB and DoD relationships. Overlaps with ISI on managed security and compliance for defense contractors, but as a portfolio offering rather than a niche focus.
• Booz Allen Hamilton: Major federal services and consulting firm with a large DIB-facing cybersecurity and CMMC advisory practice. As a broad incumbent it overlaps with ISI's compliance work but delivers it as part of much larger multi-disciplinary contracts.

Direct peers

• Exostar: Provides secure identity, credentialing, and collaboration services for the Defense Industrial Base, including FSO-facing tooling and personnel clearance workflows. Comparable to ISI's Security Control and SWFT Fingerprinting offerings.
• CyberSheath Services International: Reston-based managed cybersecurity and compliance provider purpose-built for defense contractors, offering CMMC/NIST compliance and security operations. Closely comparable to ISI's DIB-focused managed services model.
• Summit 7 Systems: Huntsville-based MSP/MSSP dedicated exclusively to the Defense Industrial Base, providing CMMC readiness, managed IT, cybersecurity, and compliance services. Direct peer to ISI in the DIB compliance niche.
• RegDOX: Secure document collaboration and CUI-handling platform purpose-built for defense contractors. Comparable to ISI's Security Control SaaS in serving DIB facility security and clearance management workflows.

Emerging players

• Coalfire Federal: Cybersecurity advisory and assessment firm with a federal practice doing CMMC L3 assessments and FedRAMP advisory. Adjacent to ISI's compliance services but primarily assessment-focused rather than full-service managed compliance.
