What your business should know about CMMC 2.0 compliance

Understanding what CMMC 2.0 is and how you can prepare as a government contractor

Stronger cybersecurity rules are coming, and CMMC 2.0 is setting the new standard for how businesses protect critical data. Starting November 10, 2025, the U.S. Department of Defense will begin adding these cybersecurity requirements to new contracts, with a rollout planned over the next few years. 

Even if your business does not work directly with the Department of Defense, understanding CMMC 2.0 is still valuable. It reflects the growing national focus on protecting sensitive information and strengthening cybersecurity across all industries.

Keep reading to learn what CMMC 2.0 is, who it applies to, and how your business can prepare.

 

What is CMMC 2.0?

CMMC stands for Cybersecurity Maturity Model Certification. In simple terms, it is a framework that helps organizations protect sensitive information and demonstrate they have strong cybersecurity measures in place. [1]

CMMC focuses on two main types of data:

• Federal Contract Information (FCI), which includes basic information about government contracts that is not public
• Controlled Unclassified Information (CUI), which includes more sensitive data that must be protected

 

If your company handles government information, works with regulated industries, or partners with businesses that do, CMMC 2.0 offers a clear roadmap for improving your cybersecurity posture. [1]

Who needs to be compliant?

CMMC applies to any business, no matter the size, that handles sensitive or government-related information, whether directly through a contract or indirectly through a subcontractor or vendor relationship. 

It is becoming a model for how all industries can strengthen their cybersecurity and prove that data is being properly safeguarded.

 

The three levels of CMMC

CMMC 2.0 includes three certification levels, based on how sensitive the information is that your business manages:

Level 1: Basic
For companies that handle only general contract information. You will need to complete a short self-assessment each year and confirm your practices are in place.

 

Level 2: Advanced
For companies that manage more sensitive data. This level has more detailed security requirements, and some businesses will need an outside audit.

 

Level 3: Expert
For companies that work with the most sensitive unclassified information. This level involves the highest standards and a government-led review.

 

Most small and mid-sized contractors will fall into Level 1 or Level 2. [2]

When does this take effect?

The rollout begins on November 10, 2025, and will take place over three years. That means new contracts will start including CMMC requirements gradually, giving businesses time to prepare.

Even if you are not currently a government contractor, following CMMC guidelines can strengthen your overall cybersecurity and make you more competitive for future opportunities.

 

How to prepare for CMMC 2.0

Here is an outline plan to get started:

1. Know what data you handle. Determine if your company works with basic contract information (FCI) or more sensitive data (CUI).

2. Review your current security practices. Make sure you have strong passwords, multi-factor authentication, secure data storage, and employee cybersecurity training.

3. Document your policies. Write down your security procedures so you can show proof during an audit or self-assessment.

4. Work with your partners. If you subcontract work, make sure those vendors also follow strong cybersecurity practices.

5. Plan for an assessment. Depending on your level, you may need a formal review by an approved third party.

6. Get expert help: Even companies working toward Level 1 can struggle to meet all requirements without professional guidance. Partnering with a qualified cybersecurity provider ensures your business meets every standard and avoids costly mistakes.

7. Keep things updated. Cybersecurity is not a one-time task. Continue monitoring and improving your systems over time.

Common mistakes to avoid

• Waiting until the last minute. The process takes time, and contracts will start including CMMC requirements in late 2025.
• Not knowing your data type. Knowing whether you handle FCI or CUI determines what level you need.
• Ignoring documentation. Written policies are key because they prove your security measures are consistent and reliable.
