Core Service Lines:

  • CMMC readiness and implementation — gap assessments, evidence collection, documentation (System Security Plans and Plans of Action & Milestones), control remediation, C3PAO coordination, assessment support, and ongoing compliance monitoring against CMMC Level 2 and NIST SP 800-171.
  • Managed IT and cybersecurity — 24/7 monitoring and incident response, patch and configuration management, identity and access controls, and secure email and data protection built for cleared and CUI environments.
  • FSO and clearance services — outsourced Facility Security Officer programs, personnel and facility clearance support, DCSA inspection preparation, and 32 CFR Part 117 (NISPOM) compliance.
  • Security Control software — an industrial security program management software to reduce the manual administration of facility and personnel clearances, annual training management, and reporting such as foreign travel and insider threats.

ISI delivers managed IT, cybersecurity, and compliance from a single accountable partner. It's a Registered Provider Organization listed by the CyberAB. On March 10, 2025, ISI became one of the first managed service providers in the U.S. to pass a CMMC Level 2 C3PAO assessment.

General Information

How does ISI differ from a general purpose MSP?

ISI's unique approach is to provide clients with integrated security, managed IT, and federal compliance services all from a single provider in order to improve coordination and accountability. ISI works exclusively within the Defense Industrial Base and was among the first managed service providers in the U.S. to reach CMMC Level 2 status, so it understands both the technical requirements of CMMC and NIST SP 800-171 and the day-to-day constraints of contractor IT teams.

How does ISI help contractors achieve and maintain NIST SP 800-171 compliance?

ISI runs an end-to-end program that starts with a gap assessment, then deploys the policies and tools needed to align with the 110 controls and 320 objectives outlined within NIST 800-171. ISI helps develop and maintain the required documentation, including System Security Plans and Plans of Action & Milestones, and provides continuous monitoring through its integrated IT, cybersecurity, and compliance services.

What is Security Control?

Security Control is ISI's FSO management platform, built for defense contractors and hosted in AWS GovCloud. It is an industrial security program management software designed to reduce the manual labor associated with maintaining facility and personnel clearances, annual training requirements, and foreign travel and insider threat reporting.

What managed IT and cybersecurity services does ISI provide?

ISI provides integrated managed IT and cybersecurity for defense contractors, combining IT management, security monitoring, and compliance support into one program. Services include 24/7 network and endpoint protection, secure system administration and patch management aligned to NIST SP 800-171 and CMMC Level 2, identity and access controls with multi-factor authentication and encryption, and helpdesk support from a team familiar with cleared facilities and export controls.

What does ISI's 24/7 monitoring and incident response include?

ISI provides 24/7/365 managed detection and response built for defense contractors, protecting Controlled Unclassified Information and maintaining alignment with CMMC Level 2, NIST SP 800-171, and DFARS 252.204-7012. It includes continuous analysis of logs and system behavior, automated and analyst-driven threat triage, incident containment and remediation, proactive threat hunting, and reporting aligned to DFARS and CMMC. ISI's SOC analysts coordinate directly with your FSO or IT lead.

Does ISI offer an outsourced FSO service?

Yes. ISI provides outsourced and virtual FSO services, ranging from full-scope support for facilities without in-house security expertise to supplemental support for existing FSOs who need extra bandwidth on NISPOM compliance and DCSA requirements. The service tracks clearances, manages onboarding and briefings, prepares for DCSA reviews, maintains required documentation, and handles ongoing compliance through the Security Control platform — giving a contractor audit-ready FSO capability without a full-time hire.

How does ISI support Facility Security Clearance (FCL) acquisition and management?

ISI guides contractors through every stage of FCL acquisition and ongoing management against DCSA and NISPOM requirements. For acquisition, ISI supports Key Management Personnel identification and Personnel Clearance submissions, prepares initial security policies and insider-threat requirements, and organizes documentation for DCSA review. In fact, our new FCL application software, Facility Control, built in alignment with DARPA's TurboFCL initiative, automatically converts your governance documents into a validated, DCSA-ready Facility Clearance package, substantially reducing the likelihood of first-round rejections and delays.

Can ISI support Microsoft 365 GCC High and CUI enclave environments?

Yes. ISI designs and deploys CUI enclaves in Microsoft 365 GCC High and Azure Government. ISI architects enclave layouts, implements compliant configurations such as MFA, encryption, and conditional access, and documents the environment for SSP, POA&M, and CMMC audit readiness.
