What is CMMC compliance?

CMMC compliance refers to meeting the standards set by the Cybersecurity Maturity Model Certification (CMMC) program. This framework was created by the DoD to ensure that contractors and subcontractors follow proper cybersecurity practices when handling sensitive government data.

The CMMC program includes three levels of certification. Each level builds on the previous one, with Level 1 focusing on basic cyber hygiene, Level 2 requiring alignment with NIST SP 800-171, and Level 3 adding more advanced security requirements. These levels help protect CUI and ensure that defense contractors meet the necessary cybersecurity standards.

CMMC 2.0 simplifies the original model, reducing the number of levels from five to three. It also allows some contractors to self-assess, depending on the type of data they handle. However, if your organization deals with CUI, you’ll likely need a third-party assessment to achieve CMMC Level 2.

6 steps to get CMMC compliant faster and avoid delays

Getting CMMC compliant doesn’t have to be overwhelming. Here are six key steps that can help you move forward with confidence and avoid common mistakes.

Step 1: Understand your data environment

Start by identifying what type of data your organization handles. If you work with CUI or FCI, you’ll need to determine which CMMC level applies to your business. This step is essential for choosing the right compliance path.

Step 2: Map your current cybersecurity controls

Compare your existing security measures to the requirements of your target CMMC level. This gap analysis helps you see where you’re already compliant and where you need to improve.

Step 3: Use a CMMC compliance checklist

A detailed checklist helps you track progress and ensures you don’t miss any critical requirements. It should include technical controls, documentation, and process maturity.

Step 4: Train your team

Everyone in your organization plays a role in cybersecurity. Make sure your staff understands the importance of compliance and knows how to follow internal security policies.

Step 5: Implement missing controls

Based on your gap analysis, take action to close any gaps. This might include updating software, improving access controls, or creating new policies.

Step 6: Schedule a pre-assessment

Before your official CMMC assessment, consider a pre-assessment to identify any remaining issues. This step can help you avoid costly delays during the certification process.

Key benefits of becoming CMMC certified

Achieving CMMC certification offers more than just compliance—it can also improve your business operations:

  • Qualify for DoD contracts that require CMMC certification
  • Strengthen your cybersecurity posture and reduce risk
  • Build trust with government and commercial partners
  • Gain a competitive edge in the defense industrial base
  • Improve internal processes and data protection
  • Prepare for future regulatory changes with confidence

What CMMC 2.0 means for defense contractors

CMMC 2.0 introduced several changes that make compliance more flexible but still enforce strong cybersecurity standards. For many defense contractors, this means re-evaluating their current systems and understanding how the new rules apply.

One major change is the reduction from five levels to three. Level 1 remains a self-assessment, while Level 2 may require a third-party assessment depending on the type of contract. Level 3, which applies to the most sensitive data, will involve government-led assessments. These changes aim to reduce the cost of CMMC compliance while still protecting national security.

Contractors must also understand the CMMC requirement for each contract. Not all contracts will require the same level, so it’s important to review contract language carefully and stay updated on DoD guidance.

5 cost factors that affect your CMMC certification journey

Several elements can influence the cost and timeline of becoming CMMC compliant. Here’s what to consider:

Factor 1: Your current cybersecurity maturity

If your systems already follow NIST SP 800-171 or similar standards, you may have fewer changes to make. This can reduce both time and cost.

Factor 2: The required CMMC level

Higher levels require more controls and documentation. For example, CMMC Level 2 involves more detailed practices than Level 1, which increases the complexity of the assessment.

Factor 3: Internal vs. external support

Hiring a consultant or managed IT provider can speed up the process, but it adds to your budget. However, it may save money in the long run by avoiding failed assessments.

Factor 4: Size and scope of your organization

Larger organizations with more systems and users will have more to document and secure. This can increase the cost of CMMC compliance.

Factor 5: Assessment readiness

If you’re well-prepared, your assessment will go more smoothly. Poor preparation can lead to delays and rework, which adds to the total cost.

How to implement CMMC controls effectively

Implementing CMMC controls requires a balance between technical solutions and process management. Start by assigning roles and responsibilities so that everyone knows who owns each control. Use project management tools to track progress and deadlines.

Documentation is also key. Keep records of your policies, procedures, and system configurations. This will make your CMMC assessment easier and show that your organization takes compliance seriously. Regular internal audits can help you stay on track and catch issues early.

Best practices for maintaining CMMC compliance

Once you’re certified, staying compliant is just as important. Here are some best practices to follow:

  • Review and update policies regularly to reflect changes in systems or staff
  • Conduct internal audits to catch issues before your next assessment
  • Provide ongoing training to keep staff aware of cybersecurity risks
  • Monitor systems for unusual activity and respond quickly to incidents
  • Stay informed about DoD updates and changes to CMMC requirements
  • Work with a trusted IT partner to manage and improve your security posture

Keeping up with these practices helps you stay compliant and ready for future assessments.

Frequently asked questions

What is the difference between CMMC certification and other compliance frameworks?

CMMC certification is specifically designed for DoD contractors and focuses on protecting CUI and FCI. Unlike general compliance frameworks like ISO or SOC 2, CMMC includes a tiered model with three levels of cybersecurity maturity. Each level builds on the previous one and aligns with federal cybersecurity requirements.

The CMMC program also requires third-party assessments for certain levels, which makes it more rigorous than self-attested frameworks. Understanding the difference between CMMC and other certifications helps you choose the right path for your business.

When will CMMC 2.0 be required for new DoD contracts?

CMMC 2.0 is expected to be fully implemented in phases, starting with Phase 1. During this rollout, the DoD will include CMMC requirements in select contracts. Full implementation may take several years, but contractors should begin preparing now.

If you want to stay eligible for DoD contracts, it’s important to understand when CMMC 2.0 will be required and how it applies to your business. Early preparation can help you avoid last-minute issues.

Who needs CMMC certification to bid on defense contracts?

Any contractor or subcontractor that handles CUI or FCI for the DoD will need to meet CMMC requirements. This includes companies of all sizes in the defense industrial base.

Even if you’re a small contractor, you may still need to become CMMC compliant depending on the type of data you handle. Review your contracts carefully to determine your obligations.

What are the three levels of CMMC, and how do they differ?

CMMC Level 1 focuses on basic cyber hygiene and allows for self-assessment. Level 2 aligns with NIST SP 800-171 and may require a third-party assessment. Level 3 includes advanced cybersecurity practices and is reserved for the most sensitive contracts.

Each level has its own set of security requirements and documentation standards. Knowing which level applies to your business is the first step toward achieving CMMC compliance.

How much does it cost to become CMMC compliant?

The cost of CMMC compliance varies based on your current cybersecurity posture, the required level, and whether you use internal or external resources. Costs can range from a few thousand to tens of thousands of dollars.

Factors like assessment readiness, organization size, and the need for new tools all affect the total cost. Planning ahead and using a CMMC compliance checklist can help manage expenses.

What is included in a CMMC Phase 1 assessment?

Phase 1 assessments focus on evaluating your readiness for CMMC certification. This includes reviewing your documentation, technical controls, and internal policies. It’s a good way to identify gaps before the official assessment.

Many businesses use Phase 1 as a trial run to ensure they meet all compliance requirements. It’s especially useful for those aiming for Level 2 or higher, where third-party assessments are required.
