What the Affirmation Requires
The annual affirmation is a formal attestation by a C-suite or senior official confirming that the organization's security posture continues to meet the requirements documented in the SSP, and that no material changes have occurred that would affect CMMC compliance status. It must be made by a named individual with authority to bind the organization, not a compliance officer acting alone.
The affirmation is tied to the organization's SPRS score: submitting it confirms that the self-assessed score posted to the SPRS portal remains accurate. If posture has changed materially (new systems added to scope, controls degraded, POA&M items unresolved beyond the accepted window), the posture must be updated before the affirmation is made.
