Do I need a C3PAO or a third-party assessor for CMMC Level 1?
Short Answer
No. Level 1 is self-assessed. A C3PAO, the accredited third-party assessor, is part of Level 2, not Level 1. You may bring in a consultant or managed IT provider to help, but it remains your self-assessment.
Where a C3PAO fits
A CMMC Third-Party Assessment Organization, authorized or accredited by the CMMC Accreditation Body, conducts Level 2 certification assessments where a contract calls for Level 2 (C3PAO). At Level 1 there is no third-party assessment and no audit. You evaluate your own systems.
Getting help without a C3PAO
A consultant, an external service provider, or a managed IT provider can assist with the work, and a requirement can be met by what that provider implements. The affirmation, however, must be signed by your own senior Affirming Official. A third party cannot affirm for you.
