Terms of Service

Our full Terms of Service are in final legal review ahead of paid launch. The principles below already govern how Muster operates today.

Last updated June 20, 2026.

  • Muster provides compliance information and document-drafting tools. It does not provide legal advice and does not attest to your implementation status. The attestation is always yours.
  • Your readiness score is a self-reported estimate computed from your own answers. It is not a certification and does not predict a C3PAO assessment outcome.
  • The free Muster Score self-assessment runs entirely in your browser. Your answers never leave your device.
  • Never enter Controlled Unclassified Information (CUI) into this platform.
  • CMMC® is a registered trademark of the U.S. Department of Defense. Muster is not affiliated with or endorsed by the DoD or the Cyber AB.
