What is a C3PAO in CMMC Certification?

CMMC c3pao featured

CMMC certification is rolling out in RFPs in the defense and federal security compliance space. This framework promotes a uniform approach to security to protect important, unclassified data that passes through third-party vendors working with federal agencies. To ensure that companies are meeting their compliance requirements, CMMC leverages outside certified assessors to serve as third-party assessment organizations (C3PAO).

In this article, we will cover the basics of C3PAOs in CMMC certification. This discussion includes a breakdown of CMMC requirements and the importance of a C3PAO in providing objective evaluations of vendor security in the defense space. 

 

What is CMMC?

CMMC is the new framework to standardize cybersecurity control implementation for vendors and agencies working with the Department of Defense (DoD) and the Executive branch and handling certain kinds of data, namely Controlled Unclassified Data (CUI). Generally, CMMC is intended to support proper security in what is known as the Defense Industrial Base (DIB). 

Since CMMC is a “Maturity Model” it represents adherence to cybersecurity best practices based on concepts of cybersecurity hygiene and capabilities:

  1. Hygiene Practices refer to the number and types of security controls an organization has in place to handle existing threats like penetration and breaches, malware and data protection.
  2. Capabilities refer to an organization’s ability to undertake specific actions as part of their overall security posture, whether as responsive or proactive measures.

With those two categories, CMMC defines five different levels of compliance:

  1. Level 1 includes “basic” cyber hygiene and the simple ability to implement those controls.
  2. Level 2 constitutes “intermediate” cyber hygiene and the ability to document their own practices and security policies (including CMMC compliance strategies). 
  3. Level 3 is based on “good” cyber hygiene and that the organization can create, establish, and implement a plan for managing their security infrastructure (including setting a mission, milestones, resourcing, and required training). 
  4. Level 4 expects the organization to practice proactive cyber hygiene and have the capability to review their own security posture and measure KPIs for effectiveness. 
  5. Level 5, the highest level, requires cyber hygiene of advanced, proactive security with the capability to standardize and optimize security processes.

For a vendor or agency to handle, transmit or store CUI in their system, they need to meet Level 3 CMMC certification at a minimum. CUI, while unclassified, still has required controls in place to protect it. That’s because Levels 3 and higher meet requirements in NIST SP 800-171.

What is a Third-Party Assessment Organization?

CMMC audits aren’t conducted by organizations themselves, nor are they conducted by a centralized governing body. Instead, assessments are run by Third Party Assessment Organizations or C3PAOs

What is a C3PAO? These organizations (typically security and/or compliance businesses with on-staff experts in various frameworks) are certified by the CMMC Accreditation Body (CMMC-AB). Similar to another governmental framework (FedRAMP), C3PAOs handle authorization by reporting to the CMMC governing body that an organization meets a specific CMMC level. Unsurprisingly, a C3PAO must meet Level 3 CMMC certification before becoming a C3PAO.

If you are seeking CMMC certification, then you’ll the first partner with a C3PAO. Following that, the C3PAO will dispatch Certified Professionals and Certified Assessors to assess your system. These assessments will determine both your security hygiene and your capabilities and report on whether or not those meet CMMC requirements at a given level. 

 

What Should I Look for in a C3PAO?

With CMMC being a relatively new framework, it can be difficult to understand what it does into selecting a proper C3PAO to partner with. There are a couple of significant features that a C3PAO should have:

  1. Certification: This may go without saying, but your C3PAO must be certified through the CMMC-AB. The CMMC-AB website includes a C3PAO marketplace where you can find certified partners.
  2. Understand that certification isn’t pushing a button: The process of getting certified, especially at higher CMMC levels, can be long and involved, which means that selecting a C3PAO to partner with should include considerations like automation and continuous monitoring. CMMC compliance in particular will be a long-term proposition, and an expert C3PAO can make that journey much more effective.
  3. Good C3PAOs will be experienced in federal compliance: In particular, FedRAMP authorization also requires 3PAOs to help with an assessment along with similar security requirements. Many established 3PAOs are currently moving towards C3PAO certification. An organization with FedRAMP or other government compliance frameworks will bring more to the table than just a C3PAO.

The truth is that while CMMC is new, many security and IT companies are flocking to C3PAO certification to get involved. Many of these organizations don’t have other experience, which means that they aren’t going to provide you with the strategy, automation and expertise that will make your compliance efforts streamlined and accurate. 

 

Conclusion

When selecting a C3PAO, work with a company that can provide you with consulting services based on your compliance and security needs. Compliance is a process, but it doesn’t have to become a simple box-checking exercise. With the right partnership, you can get compliance without sacrificing the right security for your business. 

Work with a partner that has experience in DoD, DIB or federal compliance auditing. Companies moving towards C3PAO compliance who are worth their salt will probably know their way around quick and proper assessments. Companies that perform FedRAMP 3PAO audits fall into categories, and many security firms that specialize in RMF or CCRI compliance are turning to C3PAO or CMMC-related Managed Security Services.
