CMMC Level 1 vs. Level 3: What’s the Difference?

When it comes to the Cybersecurity Maturity Model Certification (CMMC), companies must determine which certification level aligns with their cybersecurity needs and contract requirements. While CMMC features five levels, the most commonly discussed are Level 1 and Level 3, as they represent significant milestones in cybersecurity maturity. So, what’s the difference between these two levels?

CMMC Level 1: Basic Cyber Hygiene

CMMC Level 1 represents the foundation of cybersecurity requirements. This level focuses on basic cyber hygiene and includes 17 practices that are relatively straightforward to implement. These practices are designed to protect Federal Contract Information (FCI) — unclassified data that is not intended for public release but is provided by or generated for the government under a contract.

Key requirements include:

• Limiting system access to authorized users
• Using strong passwords and regularly updating them
• Maintaining basic data protection practices like antivirus and firewalls

Level 1 is best suited for companies handling non-critical DoD contracts and does not require formal documentation of processes.

CMMC Level 3: Good Cyber Hygiene

CMMC Level 3 introduces good cyber hygiene and is designed to protect Controlled Unclassified Information (CUI)— sensitive data related to national security. This level includes all 17 practices from Level 1, plus 93 additional practices across a total of 130 requirements.

Key areas of focus at Level 3 include:

• Implementing Multi-Factor Authentication (MFA)
• Encrypting CUI at rest and in transit
• Conducting regular security audits and assessments
• Establishing a formal, documented plan to manage cybersecurity risks

Level 3 is necessary for businesses working on more sensitive government contracts and requires formalized, documented cybersecurity processes.

Which Level Should Your Business Aim For?

If your company handles only Federal Contract Information and engages in less critical contracts, CMMC Level 1 may suffice. However, if your contracts involve Controlled Unclassified Information or require more stringent security measures, CMMC Level 3 is likely necessary.

Choosing the right level depends on the nature of your contracts and the sensitivity of the data you handle. Achieving Level 3 not only opens doors to higher-value contracts but also demonstrates a strong commitment to cybersecurity best practices.
