ISO/IEC 27001 ↔ NIST SP 800-171
11 canonical controls in Keel’s library satisfy clauses of both ISO/IEC 27001 and NIST SP 800-171. Implement each once, attach the evidence once, and it counts toward each standard. The overlap is the work you don’t repeat.
Controls that satisfy both
| Canonical control | ISO/IEC 27001 clauses | NIST SP 800-171 clauses |

Information is classified and handled per its sensitivity, with rules for labeling and protection.
|
A.5.12 | 3.8 |
Clause identifiers (ISO/IEC 27001 and NIST SP 800-171) are referenced factually for mapping. Keel is not affiliated with or endorsed by the bodies that publish these standards. Control descriptions are Keel’s own; a framework’s full authored control count is on its framework page.
Why this is one project, not two
On a crosswalk-native model, NIST SP 800-171 mostly lights up controls you already built for ISO/IEC 27001. You’re not re-uploading the same screenshot for a second audit. You apply the framework and see the genuine delta worth working. That’s the whole idea behind collect once, comply everywhere.
