How to Prepare for a CMMC Assessment

When defense contractors head into their formal CMMC assessment with a Certified Third-Party Assessor Organization (C3PAO), they may be overconfident in their readiness. Many organizations confuse doing the work of CMMC compliance with being able to prove the framework is being followed in practice.

To pass their CMMC assessment, contractors must eliminate common gaps in alignment and back their policies up with evidence and validation. For example, defense contractors may have discrepancies between written procedures and technical configurations and lack evidence of security activities such as log reviews and patch management.  

To give defense contractors insight into what C3PAOs are looking for during a formal CMMC assessment, we have created a video featuring Garry Meadows, Client Solutions Consultant with ProActive Solutions. In the video, Garry shares expert insights into how to avoid failing the pre-assessment phase of the CMMC assessment.

CMMC Readiness Assessment

To keep their contracts with the Department of Defense, contractors must pass their formal CMMC assessment. If your organization fails during the pre-assessment phase, you will need to start over, delaying compliance certification. The C3PAO’s role is to assess, not to advise. During a formal assessment, assessors will identify which requirements are not met, but they are not there to tell you how to fix the problem. That’s why you need to schedule a readiness assessment with ProActive Solutions before you book a C3PAO. 

ProActive Solutions works with defense contractors to help prepare them for formal CMMC assessment. We do more than give checklists of requirements. Instead, we carry out a gap analysis and deliver practical guidance on how to provide evidence and validation of alignment with the CMMC framework. Our readiness scoring uses a 0-3 scale to rate criteria to indicate how ready a company is for a given domain. By conducting the readiness assessment in a supportive environment, we promote success.

Make sure that your organization is prepared for its formal CMMC assessment. Request a CMMC Readiness Assessment from ProActive Solutions to identify gaps and resolve them before facing a C3PAO.
