Why it matters now? Since November 10, 2025, Department of Defense contracts can include the CMMC clause DFARS 252.204-7021, which makes the required CMMC level a condition of contract award (source: DoD CMMC acquisition final rule, 48 CFR, Federal Register, 10 September 2025).

Besides the need for a secure, while accessible and productive, IT network every business requires, Government Contractors must also meet the additional cybersecurity requirements of NIST SP 800-171, DFARS, and CMMC.

ICSI understands the challenging environment Government Contractors operate in. This holds especially true for small to mid-sized firms, who are squeezed between giant competitors and the need to meet stringent federal regulations for cyber security.

ICSI Government Contractor Managed IT Services work with you to meet regulatory requirements quickly. Cyber security services are a focal point of our managed IT services work with government contractors. We offer a full suite of the services you need:

  • System Security Plans
  • NIST SP 800-171, DFARS, CMMC Assessments and Remediation
  • Intrusion Detection and Response
  • Advanced Endpoint Protection
  • Microsoft Office 365 Gov
  • Business Continuity/Disaster Recovery
  • IT User Policies
  • Security Incident Response Plan
  • Multi Factor Authentication
  • Security Awareness Training
  • Network Maintenance

ICSI gives your staff the capabilities to provide continuous up-time, a 24×7 Help Desk for support, and an environment that is as adaptable as your team needs it to be.

Level 1 covers contractors that handle only Federal Contract Information (FCI). It means meeting the 15 basic safeguarding requirements in FAR 52.204-21, with a self-assessment and an affirmation entered in SPRS every year.

Level 2 covers contractors that handle Controlled Unclassified Information (CUI). It means meeting the 110 requirements of NIST SP 800-171. Depending on the contract, that is checked by a self-assessment or by an independent C3PAO assessment every three years, with an affirmation every year. Your solicitation states the level you need.

  • Gap assessment: we compare your current setup with the NIST SP 800-171 requirements and show you what is missing.
  • System Security Plan and plan of action: we write up how each requirement is met and the steps to close the gaps.
  • Remediation: multi-factor authentication, advanced endpoint protection, intrusion detection and response, backups and access controls.
  • Policies and training: IT user policies, a security incident response plan and security awareness training for your staff.
  • Ongoing support: 24×7 help desk, monitoring and network maintenance, so you stay ready for your next assessment.

Microsoft 365 GCC suits many contractors that handle FCI. Contractors that handle export-controlled (ITAR) data, or CUI that has to meet DFARS 252.204-7012, usually need GCC High. Your contracts and the type of data you hold decide which one is right, and we help you check that before any move.

Our pricing is scalable. The main things that shape it are the CMMC level you need, the number of users and devices, how many gaps the assessment finds, your Microsoft 365 licensing (GCC High costs more than the commercial version) and whether you need an independent assessment. After a free IT security assessment we give you a clear quote for your business.

What is CMMC, and does my company need it?

CMMC (Cybersecurity Maturity Model Certification) is the Department of Defense program that checks whether contractors protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). If your DoD contracts involve FCI or CUI, the solicitation states the CMMC level you need.

What is NIST SP 800-171?

NIST SP 800-171 is the set of security requirements for protecting Controlled Unclassified Information on contractor systems. DFARS 252.204-7012 requires DoD contractors that handle CUI to meet it, and CMMC Level 2 is based on it.

What is a System Security Plan (SSP)?

A System Security Plan describes your systems and how each security requirement is met. NIST SP 800-171 requires one, and assessors review it first. ICSI writes and maintains System Security Plans as part of our government contractor services.

How does ICSI help a contractor prepare for a CMMC assessment?

We assess your current environment against NIST SP 800-171 and CMMC, fix the gaps (for example multi-factor authentication, endpoint protection, intrusion detection, IT user policies, an incident response plan and staff training), document everything in your System Security Plan and keep it maintained as part of your managed IT service.

Does ICSI work with small government contractors?

Yes. Small and mid-sized contractors are our focus. We support businesses from 5 to over 400 devices.
