The Cybersecurity Maturity Model Certification is the Department of Defense helps ensure contractors protect Controlled Unclassified Information with proven, repeatable security practices. As CMMC Level 2 assessments continue to move forward across the Defense Industrial Base, contractors must be ready to demonstrate that their policies and processes are not only documented but consistently practiced in daily operations.
A central part of the assessment is the CMMC Evidence Triad. This triad focuses on three essential types of evidence: interview, examine, and test. Assessors use each category to determine whether a control is fully implemented. Many organizations invest heavily in documentation while underestimating the preparation required for personnel interviews and technical demonstrations.
This blog will help you understand how to prepare effectively for all parts of the CMMC Evidence Triad so your people, documentation, and technical safeguards work together to support a strong assessment outcome.
What Is the CMMC Evidence Triad?
To understand what assessors expect during a CMMC Level 2 assessment, it is helpful to break down the CMMC Evidence Triad and why it is so important. The triad is the method assessors use to validate whether a security control is actually implemented. Instead of relying on documentation alone, assessors evaluate three distinct forms of evidence: what people say, what the organization has documented, and what the systems show through technical validation.
The CMMC Evidence Triad is made up of three categories of evidence:
| Interview | Examine | Test |
| Assessors speak directly with the individuals who perform security-related tasks to confirm they understand and execute their responsibilities correctly. | Assessors review documented policies, procedures, plans, and artifacts that define how each control is expected to operate within the organization. | Assessors observe or verify technical safeguards in action through live demonstrations, screenshots, system outputs, or configuration settings to ensure controls function as documented. |
These three evidence categories are interconnected. Strong alignment among interview, examine, and test results shows that the organization is operating as documented. If one area is inconsistent or incomplete, assessors may determine the control is not fully implemented.
Understanding how the CMMC Evidence Triad works is an essential foundation for successful readiness.
Why Documentation Alone Falls Short
Once organizations understand the purpose of the CMMC Evidence Triad, many quickly realize a common issue. Documentation alone cannot carry a CMMC assessment. Policies and procedures are important, but assessors weigh interview and technical evidence equally. If personnel cannot explain how controls work or technical systems do not reflect what is documented, the documentation loses credibility.
This disconnect appears frequently. Staff may not know how their responsibilities relate to specific controls. Systems may be configured differently than policies described. Logs may not be retained long enough, or monitoring tools may not generate the output expected. Even small inconsistencies can create findings during a CMMC Level 2 assessment.

Strong documentation is necessary, but it is only effective when supported by knowledgeable personnel and fully implemented technical safeguards. The organizations that perform well in CMMC assessments are those that continuously align what is written with what is practiced and what their systems demonstrate. Recognizing gaps between documentation and reality is the first step toward full implementation across the CMMC Evidence Triad.
Preparing for the Interview: Empower Your Team
With documentation in place, the next part of preparing for preparing the CMMC Evidence Triad is ensuring personnel are ready for the interview portion. Assessors prioritize interviews because they want to hear directly from the people who execute and oversee security practices. Their goal is to confirm that personnel understand their responsibilities and can describe how controls are applied in daily operations.
Interview preparation often feels uncomfortable for teams who are not used to formal assessments. The good news is that assessors are not looking for memorized policy language. They want clarity, confidence, and honest explanations of how tasks are performed. When staff can describe their processes naturally and accurately, it signals strong operational maturity.
Preparing your team involves more than reviewing policies. Internal mock interviews, real-world scenario discussions, and role-based training can help eliminate uncertainty and improve consistency. At MAD Security, our Virtual Compliance Management and readiness exercises give organizations a structured way to help personnel speak confidently and represent their work accurately. When interview readiness is strong, the entire CMMC Evidence Triad becomes more stable and reliable.
Preparing for the Test: Validate Technical Controls
Just as interviews validate the human side of compliance, the test portion of the CMMC Evidence Triad validates the technical side. Assessors will expect to see proof that your security tools and system configurations behave exactly as your documentation claims. This is often the point where organizations discover gaps between intention and configuration.
During the test portion of the CMMC Evidence Triad, assessors commonly request to see:
| Multifactor authentication enforcement | to verify it is applied across all required systems |
| Log retention settings | that demonstrate appropriate storage and duration |
| Audit records | showing activity tracking and evidence of monitoring |
| Encryption details | for data at rest and in transit |
| Endpoint configurations | that reflect secure system settings |
| Monitoring outputs | that confirm alerts, events, and security activity are being captured |
Technical readiness requires reviewing system configurations, validating tool outputs, and confirming that safeguards perform as expected. MAD Security helps organizations prepare for this step through SOC services, vulnerability scans, endpoint monitoring, and technical readiness assessments. These services ensure your environment is operating exactly as required before assessors begin reviewing your controls
Aligning the Triad: Ensure Consistency Across All Evidence
After preparing documentation, personnel, and technical safeguards, the final step is ensuring all three elements of the CMMC Evidence Triad align. Assessors look closely for consistency across interview, examine, and test results. When these areas work together, the organization demonstrates strong operational control. When they do not, inconsistencies become immediate findings.
Misalignment is common. A policy may reference an outdated system, while the current configuration behaves differently. Staff may describe a procedure based on old habits rather than current requirements. A technical tool may be implemented but not configured to match what the documentation states. These discrepancies can make it clear that a control is not fully implemented.
Alignment requires intentional coordination across people, processes, and technology. MAD Security uses the Completely MAD Security Process to help organizations bring all three areas together, so the documentation reflects actual behavior, and the technical safeguards reinforce both.
Your Next Step Toward a Confident and Successful CMMC Assessment

Preparing for a CMMC assessment is more than a documentation exercise. True readiness comes from ensuring that your people, your documentation, and your technical environment all reflect the same practices. When each part of the CMMC Evidence Triad aligns, organizations demonstrate strong implementation and significantly improve their likelihood of assessment success.
Many organizations struggle not because they lack documentation but because they lack alignment. MAD Security helps contractors bridge these gaps by strengthening documentation, preparing personnel, and validating technical safeguards before assessors arrive.
If you want confidence heading into your next CMMC Level 2 assessment, MAD Security is ready to help you align all three parts of the CMMC Evidence Triad and achieve complete readiness.
