What is CMMC?

What is CMMC?

If you’re a defense contractor or part of the Department of Defense (DoD) supply chain, you’ve likely heard of CMMC 2.0 but what does it truly mean for your business? The Cybersecurity Maturity Model Certification (CMMC) is more than a regulation. It’s a necessary framework designed to protect sensitive government information and keep your organization eligible for defense contracts. 

At MAD Security, we simplify cybersecurity and compliance. As a CMMC Level 2 Certified Managed Security Services Provider (MSSP) and Registered Provider Organization (RPO), we help DoD contractors confidently navigate the path to compliance. 

What Does CMMC 2.0 Mean for Your Business? 

CMMC stands for Cybersecurity Maturity Model Certification. Created by the Department of Defense, it’s a security framework developed to safeguard Controlled Unclassified Information (CUI) and Federal Contract Information (FCI) across the Defense Industrial Base (DIB). 

The initial version of CMMC had five maturity levels. In response to industry feedback, CMMC 2.0 introduced a more streamlined model with just three certification levels. These levels align closely with NIST SP 800-171 and existing federal acquisition regulations, making the path to compliance clearer and more practical. 

For defense contractors and subcontractors aiming to win DoD contracts, understanding and preparing for CMMC 2.0 compliance is essential. 

Do You Need to Comply with CMMC? 

If your company handles, processes, or stores CUI or FCI, the answer is YES. 

CMMC 2.0 applies to all contractors and subcontractors in the DoD supply chain, regardless of size or scope. Whether you are a prime contractor bidding on a large defense program or a subcontractor providing a niche service, you are expected to meet the appropriate CMMC level based on the sensitivity of the data you manage. 

Without certification, you may be disqualified from future opportunities. 

A Quick Look at the 3 CMMC Levels

CMMC 2.0 organizes requirements into three levels. Each level reflects a different degree of cybersecurity maturity and implementation. 

Level 1: Foundational

This level applies to companies that only handle Federal Contract Information (FCI). It focuses on basic cybersecurity hygiene and includes 17 security controls from FAR 52.204-21. These involve access control, data protection, and user authentication. 

Level 2: Advanced

Level 2 is the most common requirement across the DIB. It applies to organizations managing Controlled Unclassified Information (CUI) and requires full alignment with NIST SP 800-171, a total of 110 security practices. 

Depending on contract sensitivity, some companies may self-assess. However, third-party assessments by a Certified Third-Party Assessor Organization (C3PAO) are mandatory for most. 

Level 3: Expert

This level is reserved for companies handling the most sensitive DoD information. It incorporates NIST SP 800-172 controls, which go beyond the foundational and advanced requirements to include enhanced threat detection and cyber resilience practices. 

Assessment requirement: Government-led audits every 3 years. 

Why CMMC Isn’t Just About Compliance

CMMC is more than checking a box. It’s about protecting your business, your contracts, and national security. Failure to comply could result in lost contracts, an increased risk of cyberattacks, and exposure to False Claims Act violations if you inaccurately self-attest. On the other hand, demonstrating strong cybersecurity maturity builds trust with prime contractors and DoD agencies. 

CMMC also signals that your organization takes security seriously, which can set you apart from competitors in the federal space. 

How MAD Security Simplifies CMMC Compliance

Whether you're preparing for Level 1, Level 2, or supporting a future Level 3 goal, our team is with you every step of the way. 

Don’t Wait Until It’s Too Late

CMMC 2.0 is being implemented in phases under the proposed rule tied to DFARS Clause 252.204-7021.  Phase 1 begins in late 2025, at which point select Department of Defense contracts will begin requiring CMMC Level 1 self-assessments or Level 2 certifications as a condition for award. 

Delaying your preparation could lead to serious setbacks, such as: 

• Long delays due to a limited number of Certified Third-Party Assessor Organizations (C3PAOs) 

• Ineligibility for new contract awards or option periods 

• Being passed over by prime contractors who already expect CMMC readiness from their partners 

Getting started now positions your business ahead of the curve and ensures you are fully prepared when these requirements become standard across most DoD contracts during the rollout.
