Can NIST SP 800-171 Rev. 3 documentation support future CMMC readiness?

The smart move for defense contractors is to start implementing NIST SP 800-171 Rev.3 documentation to support future CMMC readiness.

Should defense contractors prepare for NIST SP 800-171 Rev. 3 now?

Yes. Defense contractors should prepare now, but not at the expense of current CMMC or DFARS obligations.

NIST SP 800-171 Rev. 3 will become mandatory for DoD/DoW contractors once government rulemaking is published and even then there will be a transition period.

Does DoD require NIST SP 800-171 Rev. 3?

As of July 2026, the DoD/DoW does not require NIST SP 800-171 Rev 3; Rev 2 remains the CMMC assessment baseline under the DFARS class deviation.
