Understanding the Current State of CMMC Compliance

Cybersecurity Maturity Model Certification (CMMC) continues to be one of the most important cybersecurity initiatives affecting the Defense Industrial Base (DIB).

For organizations that handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), understanding CMMC requirements is no longer optional. Compliance is becoming a contractual requirement for many Department of Defense (DoD) opportunities.

Yet many contractors still have questions:

  • What changed with CMMC 2.0?
  • Do we need a third-party assessment?
  • How does NIST SP 800-171 fit into the process?
  • What should we be doing today to prepare?

This guide breaks down the current CMMC landscape and outlines practical steps organizations can take to strengthen their compliance readiness.

What Changed Under CMMC 2.0?

One of the biggest changes introduced by CMMC 2.0 was the simplification of the framework.

The original model included five maturity levels. CMMC 2.0 streamlined those requirements into three levels designed to better align with existing cybersecurity standards and reduce unnecessary complexity.

The updated model focuses heavily on NIST frameworks already familiar to many defense contractors.

Level 1: Foundational

Organizations handling Federal Contract Information (FCI) must implement basic cybersecurity practices designed to protect information and reduce common risks.

Assessment Method:

  • Annual self-assessment

Level 2: Advanced

Organizations handling Controlled Unclassified Information (CUI) must implement the 110 security requirements outlined in NIST SP 800-171.

Assessment Method:

  • Self-assessment or third-party assessment depending on contract requirements

Level 3: Expert

Organizations supporting highly sensitive programs may be required to implement additional controls based on NIST SP 800-172.

Assessment Method:

  • Government-led assessments

Why NIST SP 800-171 Remains Critical

Many organizations focus exclusively on CMMC and overlook the fact that NIST SP 800-171 remains the foundation for most Level 2 compliance requirements.

The 110 controls within NIST 800-171 address areas such as:

  • Access Control
  • Incident Response
  • Security Awareness Training
  • Configuration Management
  • Risk Assessment
  • Audit and Accountability
  • System and Communications Protection

For most defense contractors, improving NIST 800-171 compliance is one of the most effective ways to prepare for future CMMC assessments.

Common Challenges Contractors Face

Many organizations discover that technology is only one part of compliance.

Common challenges include:

Documentation Gaps

Policies, procedures, and supporting evidence are often incomplete or outdated.

Limited Internal Resources

Many organizations lack dedicated cybersecurity or compliance personnel.

POA&M Management

Identifying and tracking remediation efforts can quickly become difficult without a structured process.

Assessment Readiness

Organizations often struggle to determine whether they are truly prepared for an assessment until significant gaps are discovered.

What Contractors Should Be Doing Right Now

Rather than waiting for a contract requirement to appear, organizations should focus on building a strong compliance foundation.

Recommended actions include:

Conduct a Gap Assessment

Understand where your current environment stands against NIST SP 800-171 and applicable CMMC requirements.

Review Documentation

Ensure policies, procedures, system security plans, and supporting evidence are current and maintained.

Strengthen Security Controls

Address technical, administrative, and operational gaps before assessment timelines become critical.

Establish Ongoing Governance

Compliance is not a one-time project. Organizations should develop processes for monitoring, maintaining, and improving their cybersecurity posture over time.

Compliance Is About More Than Passing an Assessment

One of the biggest misconceptions surrounding CMMC is that the goal is simply to pass an assessment.

The true objective is to create a stronger cybersecurity program capable of protecting sensitive information, supporting contract eligibility, and reducing organizational risk.

Organizations that approach compliance as an ongoing business process often achieve better outcomes than those treating it as a one-time certification effort.
