Our C3PAO Assessment Process
1
Preliminary Proceedings
First things first, we’ll confirm your request for a CMMC assessment and make sure we have all the details we need. We’ll also check for any conflicts of interest, handle the contract, and officially report the start of your assessment to the DoD through CMMC eMASS. Before we move forward, we’ll take a quick look at your readiness for assessment to make sure you’re set up for success.
2
Pre-Assessment
Before jumping into the full assessment, we’ll do a readiness check to see if you’re truly prepared for CMMC Level 2 certification. This means reviewing your System Security Plan (SSP), checking that all necessary evidence is in place, and confirming that your assessment scope is accurate. If we find major gaps, we’ll pause the process and report to the DoD—giving you a chance to address those issues before moving forward.
3
Formal Assessment
Now it’s time for the real work. Our CMMC-certified assessors will take a deep dive into your security controls, applying sampling methods to evaluate how well you meet CMMC Level 2 and NIST 800-171A requirements. We’ll look at your external service providers, cloud service providers, and overall cybersecurity posture, meeting with you daily to ensure transparency.
4
Reporting
Once the assessment is complete, we’ll put together a detailed report that includes our findings, scoring, and recommendations. We’ll also hold an out-brief meeting to go over the results with you and answer any questions. Then, we’ll submit the final assessment results to CMMC eMASS for official review. If there’s anything you need to appeal, we’ll help you through that process.
5
Fixing Issues & POA&M Closeout
If there are any gaps or deficiencies in your assessment, you may need to complete a Plan of Action and Milestones (POA&M) before earning full certification. We’ll guide you through closing out those gaps so you can meet the necessary CMMC compliance standards as quickly as possible.
6
Certification
Once everything checks out, we’ll issue your CMMC Level 2 Certificate! This means you’ll either receive a Conditional or Final Certification, depending on your compliance status. With this in hand, you can confidently move forward with DoD contracts knowing you’re officially compliant with CMMC regulations and ready to protect Controlled Unclassified Information (CUI).

Key Benefits of a CMMC C3PAO
Meet DoD Cybersecurity Requirements
CMMC compliance is mandatory for handling CUI. Our C3PAO assessments verify that your security controls align with NIST 800-171.
Streamlined Certification Process
Our CMMC-certified assessors follow the CMMC Assessment Process (CAP) to make certification structured, transparent, and efficient, so you can focus on securing contracts, not paperwork.
Strengthen Your Cybersecurity Posture
Through our independent assessment process, we help identify gaps in security controls, allowing you to enhance your cybersecurity framework.
Minimize Compliance Risks & Avoid Penalties
Failing to meet CMMC requirements can result in lost contracts and compliance penalties. Our expert-led assessments help you identify weaknesses early, giving you a clear roadmap to close gaps before they impact your business.
Competitive Advantage in Government Contracting
Organizations with a CMMC certification stand out as trusted, security-first partners in the defense industrial base (DIB). Achieving certification gives your business a competitive edge in winning DoD contracts.
Expert Guidance Every Step of the Way
Beyond assessments, TestPros provides valuable insights, recommendations, and ongoing support to help you navigate compliance requirements—ensuring long-term cybersecurity success.
Frequently Asked Questions
What is a C3PAO in CMMC?
A C3PAO (CMMC Third-Party Assessor Organization) is an independent organization authorized by the Cyber AB to conduct official CMMC Level 2 assessments for businesses that handle Controlled Unclassified Information (CUI).
What is the cost of a C3PAO assessment?
The cost of a C3PAO assessment varies based on several factors, including:
- Readiness Level – If your organization has a well-documented System Security Plan (SSP) and has conducted a self-assessment, the effort required may be lower.
- Assessment Complexity – The size and structure of your environment (enclave vs. enterprise), the number of systems and locations, and whether onsite visits are needed can impact costs.
- Level of Effort – More complex networks or organizations with third-party service providers (e.g., cloud environments) may require additional assessment time and resources.
Pricing can range from tens of thousands to over $100,000, depending on these factors. To get an accurate quote, organizations should contact us to undergo a pre-assessment readiness review to determine the scope and effort required for the CMMC Level 2 certification process.
How does a C3PAO assessment work?
A C3PAO assessment is a formal, independent evaluation to verify that an organization meets CMMC Level 2 requirements. The assessment follows the CMMC Assessment Process (CAP).
- Initial Review & Planning – The process starts with a review of your System Security Plan (SSP) and assessment scope to confirm readiness. The C3PAO works with your team to establish the logistics of the assessment, including the required documentation and interviews.
- Security Control Evaluation – Our certified assessors will conduct an in-depth review of your cybersecurity controls, following the CMMC framework and NIST 800-171A assessment objectives. This includes validating technical implementations, policies, and procedures through document reviews, system inspections, and discussions with key personnel.
- Scoring & Findings Report – Once the assessment is complete, your organization will receive a scoring report based on CMMC guidelines, outlining areas where security requirements are met and where improvements may be needed. The results are then submitted to CMMC eMASS for review.
- Certification Decision – If all CMMC Level 2 requirements are satisfied, your organization will receive a CMMC certification, demonstrating compliance and allowing you to continue working with the DoD.
To maintain Level 2 compliance, a C3PAO assessment is required every three years, with annual reaffirmations.
How long does it take?
A C3PAO assessment typically takes about 1 week, with 2 weeks of preparation beforehand. The final report and submission to CMMC eMASS may add additional time depending on findings and follow-ups.
Do we qualify for a self-assessment?
Some organizations seeking CMMC Level 2 certification can conduct self-assessments if they handle non-critical CUI, while those dealing with critical CUI typically require third-party assessments. The DoD determines which contractors fall into each category based on the sensitivity of the information they handle and the potential impact on national security.
To help organizations understand their current CMMC readiness, we offer a free CMMC self-assessment questionnaire that includes crucial questions to evaluate your cybersecurity posture and provides official resources you can use at no cost.
