Frequently asked questions
How does NIST 800-171 relate to CMMC?
How does NIST 800-171 relate to CMMC?
CMMC (Cybersecurity Maturity Model Certification) builds on NIST 800-171. CMMC Level 2 aligns directly with NIST 800-171 requirements. Achieving NIST 800-171 compliance prepares you for CMMC Level 2 certification.
Is self-assessment sufficient?
Is self-assessment sufficient?
Currently, self-assessment is accepted, but CMMC 2.0 will require third-party assessments for Level 2 (equivalent to NIST 800-171). Prepare now for the transition.
