The NIST SP 800-171 Rev 3 to NIST SP 800-161 Rev 1 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-161 Rev 1 controls your existing NIST SP 800-171 Rev 3 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
Coverage does not run both ways. NIST SP 800-171 Rev 3 into NIST SP 800-161 Rev 1 lands at 38.2%, while NIST SP 800-161 Rev 1 into NIST SP 800-171 Rev 3 lands at 52.6%, on the same two control sets. That is not a rounding difference. It is the whole reason these are two separate reports: one asks what your NIST SP 800-171 Rev 3 evidence buys you for NIST SP 800-161 Rev 1, the other asks the reverse.
73 of 191 NIST SP 800-161 Rev 1 controls are evidenced by work you have already done for NIST SP 800-171 Rev 3. 118 are genuine gaps.
A sample of what the report says
Access control family policy and procedures are explicitly required and reviewed.
Grounded in 03.15.01 Policy and Procedures. Confidence high, survived the refutation pass.
Governs what supply chain information is shared, with whom, and under what handling conditions.
Every one of the 73 evidenced controls and 118 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
51 of 97 NIST SP 800-171 Rev 3 controls are evidenced by work you have already done for NIST SP 800-161 Rev 1. 46 are genuine gaps.
A sample of what the report says
Sets and verifies the terms under which external systems may be used.
Grounded in 161R1-AC-20 Use of External Systems. Confidence high, survived the refutation pass.
Define, establish, modify, disable, and remove account types; assign managers; specify membership conditions; authorize access; monitor account use; notify managers on triggering events; require re-authorization at defined frequencies.
Every one of the 51 evidenced controls and 46 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
- Every evidenced control, with the reasoning behind it
- Every gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 85% in the header counts how many NIST SP 800-171 Rev 3 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-161 Rev 1 controls are actually evidenced, after a pass that argued against each mapping and kept only what survived. They answer different questions and they are not meant to agree.
A crosswalk narrows the work. It does not replace an audit, and your assessor may take a different view on individual controls. Mappings between frameworks are judgements, not text printed in either standard, which is why every claim in the report shows its reasoning. Questions go to support@theartofservice.com.

What are the key differences between NIST SP 800-171 Rev 3 and NIST SP 800-161 Rev 1?
NIST SP 800-171 Rev 3 has 97 controls across its framework, while NIST SP 800-161 Rev 1 covers 191 controls. Direct mapping analysis identifies 82 overlapping controls (85% coverage). The frameworks diverge most significantly in 03.13 SC (System and Communications Protection), where 4 NIST SP 800-171 Rev 3 controls have no direct NIST SP 800-161 Rev 1 equivalent.
How many controls map between NIST SP 800-171 Rev 3 and NIST SP 800-161 Rev 1?
Of 97 total NIST SP 800-171 Rev 3 controls, 82 map directly to NIST SP 800-161 Rev 1 controls, representing 85% coverage. The remaining 15 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping NIST SP 800-171 Rev 3 to NIST SP 800-161 Rev 1?
15 NIST SP 800-171 Rev 3 controls have no direct equivalent in NIST SP 800-161 Rev 1. The highest concentration of gaps is in 03.13 SC (System and Communications Protection) with 4 unmapped controls. These gaps represent areas where additional controls, policies, or documentation must be created to achieve compliance with both frameworks.
Which control domains have the most gaps between NIST SP 800-171 Rev 3 and NIST SP 800-161 Rev 1?
The domain with the highest gap count is 03.13 SC (System and Communications Protection) (4 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
