CMMC Readiness is the preparation phase. It is consultative, meaning services like ours help you fix issues, conduct gap analyses, develop documentation (SSP, policies), and implement controls (remediation).
The CMMC Assessment is the formal, third-party verification performed by a C3PAO to certify that your controls are in place, operational, and effective. Assessment services are purely evaluative—they only examine your pre-existing state to assign a certification score. You must complete readiness before an assessment.
