ISO 27701 vs GDPR: How the Standard Maps to the Regulation

GDPR is binding EU/EEA regulation. ISO/IEC 27701 is a voluntary (but widely buyer-required) management-system standard. Certification does not equal “GDPR certified,” but a mature PIMS is strong accountability evidence under Articles 5(2) and 32.

Different instruments: Supervisory authorities enforce GDPR. Accredited certification bodies certify ISO 27701. Use the standard to organise evidence; do not treat the certificate as a legal safe harbour.

Practical Mapping Tips

Use RoPA / inventory rows to feed both Art 30 and PIMS operation evidence
DPIA (Art 35) workflows feed PIMS planning and risk treatment
Art 32 TOMs align with security control operation and SIEM monitoring
Keep legal opinions and SA correspondence outside the SoA—link them as supporting evidence

Frequently Asked Questions

Does ISO 27701 certify GDPR compliance?

No. It certifies a PIMS against the standard. GDPR compliance remains a legal determination.

Should we do GDPR readiness or ISO 27701 first?

If buyers demand a certificate, start PIMS scoping early. If SA exposure or EU customers dominate, prioritise legal accountability artefacts first — then align the SoA.

Is UK GDPR covered?

UK GDPR is a separate regime. The same PIMS can support both if scoped and mapped carefully.
