The ACSC Essential Eight to NIST SP 800-171 Rev 3 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-171 Rev 3 controls your existing ACSC Essential Eight work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
18 of 97 NIST SP 800-171 Rev 3 controls are evidenced by work you have already done for ACSC Essential Eight. 79 are genuine gaps.
A sample of what the report says
Privileged access for users and services is limited to only what their duties require.
Grounded in E8-ADMIN-ML3 Restrict Administrative Privileges (ML3). 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 18 evidenced controls and 79 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
This direction has not been through crosswalk review and sign off, so no coverage figure is published for it. Reporting an unreviewed number would be worse than reporting none. It can be built to order at the same price as a pair that is already on the shelf.
If the two frameworks turn out to have too little in common for a crosswalk to help you, we say so and refund it rather than send a number worth nothing.

Why this page shows two different percentages. The 83% in the header counts how many ACSC Essential Eight controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-171 Rev 3 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 ACSC Essential Eight and NIST SP 800-171 Rev 3?
ACSC Essential Eight has 24 controls across its framework, while NIST SP 800-171 Rev 3 covers 97 controls. Direct mapping analysis identifies 20 overlapping controls (83% coverage). The frameworks diverge most significantly in Regular Backups, where 2 ACSC Essential Eight controls have no direct NIST SP 800-171 Rev 3 equivalent.
How many controls map between ACSC Essential Eight and NIST SP 800-171 Rev 3?
Of 24 total ACSC Essential Eight controls, 20 map directly to NIST SP 800-171 Rev 3 controls, representing 83% coverage. The remaining 4 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ACSC Essential Eight to NIST SP 800-171 Rev 3?
4 ACSC Essential Eight controls have no direct equivalent in NIST SP 800-171 Rev 3. The highest concentration of gaps is in Regular Backups with 2 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 ACSC Essential Eight and NIST SP 800-171 Rev 3?
The domain with the highest gap count is Regular Backups (2 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
