The Road to CMMC 2.0: What NIST 800-171A Means for Contractors

The cybersecurity landscape for defense contractors is changing rapidly. With the rollout of CMMC 2.0, compliance expectations are becoming more stringent yet more streamlined, aligning closely with the well-established NIST 800-171A standards. For contractors aiming to stay competitive in the defense sector, understanding and implementing these requirements is no longer optional—it’s mission-critical.

What is NIST 800-171A?

  • NIST 800-171A is the "Assessment Guide for Security Requirements for Controlled Unclassified Information (CUI)." It provides the procedures and methodologies to assess the implementation of the security requirements outlined in NIST SP 800-171.

    In simple terms, NIST 800-171A is the playbook used to verify whether an organization has properly implemented the security controls required to protect CUI. These controls include:

    • • Access control

      • Incident response

      • Risk assessment

      • Security assessment

      • System and communications protection

    NIST 800-171A doesn’t introduce new requirements—instead, it ensures that the existing ones are thoroughly tested and validated.

How NIST 800-171A Relates to CMMC 2.0

  • CMMC 2.0 has restructured the original five-level model into three levels:

    • • Level 1: Foundational

      • Level 2: Advanced (aligned with NIST 800-171 requirements)

      • Level 3: Expert

    For contractors seeking to achieve Level 2 certification, compliance with NIST 800-171—validated through NIST 800-171A assessment methods—is essential.

    This shift streamlines the compliance process, making NIST 800-171A the gold standard for verification. Organizations must now:

    • • Conduct self-assessments or undergo third-party assessments depending on the sensitivity of their work.

      • Provide objective evidence for each control.

      • Maintain readiness for audits by the Department of Defense (DoD) or authorized C3PAOs (Certified Third-Party Assessment Organizations).

Why Contractors Should Care

  • Failing to comply with CMMC 2.0 and NIST 800-171A standards can have severe consequences, including:

    • • Loss of existing DoD contracts

      • Ineligibility for new government contracts

      • Financial penalties and reputational damage

    On the other hand, proactive compliance offers benefits:

    • • Competitive advantage in securing contracts

      • Improved cybersecurity posture

      • Streamlined internal processes and risk management

Steps to Get Started

  • 1. Conduct a Gap Assessment Identify where your current cybersecurity measures fall short of NIST 800-171 requirements.

  • 2. Develop a System Security Plan (SSP) Document your security controls, practices, and procedures.

  • 3. Create a Plan of Action and Milestones (POA&M) Outline how you will address any deficiencies identified in the gap assessment.

  • 4. Implement and Monitor Controls Put security controls into action and establish continuous monitoring.

  • 5. Engage a Compliance Management Platform Use tools like IntelComp Compliance Management System to simplify documentation, track progress, automate assessments, and ensure continuous audit readiness.
