Mapping NIST CSF 2.0 to ISO 27001
Connect outcome-based CSF subcategories to implementable Annex A controls.
CSF 2.0 to ISO 27001 informative-reference crosswalk
CSF 2.0 describes outcomes across six functions, Govern, Identify, Protect, Detect, Respond and Recover; ISO 27001 describes a management system plus Annex A controls. The new GOVERN function aligns closely with ISO 27001 clause 5 leadership and clause 6 planning, plus the organizational controls in Annex A 5. PROTECT maps largely to the people, physical and technological themes of Annex A; DETECT, RESPOND and RECOVER align with logging, incident-management and continuity controls. ISMS Copilot generates a subcategory-to-control table modelled on NIST\'s own informative-reference approach, showing where an ISO 27001 control evidences a CSF outcome, where a CSF subcategory has no single Annex A counterpart, and where ISO 27001 clauses 4 and 9 cover context and effectiveness measurement that CSF leaves to the organization. CSF is voluntary and self-attested; the mapping helps implement once and report against both, without implying certification of CSF.

Does ISO 27001 satisfy NIST CSF 2.0?
ISO 27001 controls evidence a large share of CSF 2.0 outcomes, but CSF is an outcome framework with no certification. The Copilot maps Annex A controls to CSF subcategories so you can build a defensible Profile, not a CSF certificate.
How does the GOVERN function map to ISO 27001?
GOVERN aligns most closely with ISO 27001 clause 5 leadership, clause 6 planning, and the organizational controls in Annex A 5, covering roles, policy, risk strategy and oversight. The crosswalk shows the specific clause and control references.
Is this an official NIST mapping?
It is an informative mapping in the spirit of NIST\'s own informative references, built from CSF 2.0 and ISO 27001:2022. It is not published or endorsed by NIST or ISO and does not assert exact equivalence.
