NIST Privacy Framework 1.1 Explained (and vs ISO 27701)

NIST Privacy Framework 1.1 functions and how they compare with an ISO 27701 privacy information management system.

Published: September 2026 Compliance · Privacy 8–12 min read

The NIST Privacy Framework organises privacy risk management similarly to the Cybersecurity Framework — with functions that help communicate programme status to executives.

ISO 27701 remains the common certification path for a PIMS; NIST PF is often the US-friendly operating language layered on top.

Complementary: Use NIST PF for governance conversations; use ISO 27701 when customers need a certifiable PIMS.

Core idea

Identify-privacy risk, govern, control, communicate, and protect-related activities (per the Framework's function model). Map each to owners and metrics.

Versus ISO 27701

Adoption path

Build a profile from business objectives, map to existing ISO/GDPR controls, and track gaps in GRC with evidence links.
