What This Means for Your Organization:
- Don't start with a C3PAO. They can’t consult or help you prepare. You need to be fully ready before you call them.
- Consultants help you get ready, but only if they understand the nuances of your business and compliance goals.
- MSSPs help implement and maintain your security. Without operational support, your compliance won’t stick.
Let’s say you’re a DoD contractor or subcontractor preparing for CMMC Level 2. You’ve got requirements. You’ve got deadlines. And you’ve got a lot of acronyms coming at you. The most common misstep? Not knowing who does what, and hiring the wrong help at the wrong time. Here’s the breakdown.
Managed Security Services Provider (MSSP)
CMMC isn’t just about having the right documents. It’s about proving you’re actively doing the work. That’s where MSSPs shine. They help you implement and sustain the technical side of your compliance. Your MSSP manages your day-to-day cybersecurity operations. Think threat detection, system patching, log monitoring, and incident response. Total Assure can provide Managed Security Services to help support your CMMC journey.
Consultant: Your CMMC Readiness Partner
A consultant helps you identify gaps, interpret the CMMC requirements, and build a plan to become compliant. This includes readiness assessments, policies, SSP/POA&M development, and remediation strategies. They are important because you don’t want to find out you missed a requirement during your official assessment. A consultant helps you avoid costly rework, and ensures your people, processes, and tools are aligned. Total Assure has the team ready to help you get prepared for CMMC.
Certified Third-Party Assessor Organization (C3PAO)
C3PAOs are authorized by the CMMC-AB to conduct formal assessments. They verify if your organization actually meets CMMC requirements. and they are the only entity that can award you a CMMC certification. But it is important to note that they cannot help you prepare, because it would be a conflict of interest. If you approach a C3PAO before you're ready, you're likely to fail and you'll have to wait and pay to try again.

So, Who Do You Call First?
You may need all three, but not all at once. Here’s the order of operations:
- Start with a consultant (like Total Assure) to evaluate your readiness, close your gaps, and prepare your team.
- Work with an MSSP to implement, monitor, and maintain your security controls over time. Total Assure can help here.
- Call a C3PAO once your consultant confirms you’re truly ready for an audit.
