Key Takeaways
| Point |
Summary |
| Design alignment |
ISO 27701 explicitly designed to support GDPR compliance |
| Mapping provided |
Annex D maps controls to GDPR articles |
| Controller coverage |
Annex A controls map to controller obligations (Art. 5-25) |
| Processor coverage |
Annex B controls map to processor obligations (Art. 28-33) |
| Important caveat |
Certification supports but doesn't equal GDPR compliance |
| Documentation benefit |
ISO 27701 creates GDPR accountability evidence |
Quick Answer: ISO 27701 provides structured support for GDPR compliance through explicit mapping between its controls and GDPR articles. Annex A controls address controller requirements, Annex B addresses processor requirements. However, ISO 27701 certification demonstrates systematic privacy management, not legal GDPR compliance, which requires additional legal and operational measures.
Understanding the Relationship
Certification vs. Legal Compliance
| Aspect |
ISO 27701 Certification |
GDPR Compliance |
| Nature |
Technical standard certification |
Legal requirement |
| Scope |
Privacy management system |
All GDPR obligations |
| Assessment |
Auditor against standard |
Supervisory authority interpretation |
| Outcome |
Certificate |
Ongoing legal compliance |
| Liability |
None from certification |
Legal penalties for non-compliance |
ISO 27701 certification supports GDPR compliance by:
- Providing systematic framework for privacy management
- Creating documented evidence of accountability
- Establishing repeatable processes for rights and obligations
- Demonstrating commitment to privacy protection
ISO 27701 certification does not:
- Guarantee GDPR legal compliance
- Replace legal analysis of processing activities
- Substitute for Data Protection Impact Assessments
- Eliminate need for legal counsel on complex matters

Common Questions
Does ISO 27701 certification guarantee GDPR compliance?
No. Certification demonstrates you have a systematic privacy management system, but GDPR compliance involves legal interpretations, specific factual circumstances, and ongoing operational compliance that certification cannot verify.
Can ISO 27701 replace a GDPR compliance assessment?
No. ISO 27701 provides framework and controls, but legal analysis of your specific processing activities, legal bases, and regulatory obligations still requires legal expertise and judgment.
How do auditors assess GDPR alignment?
ISO 27701 auditors assess whether you've implemented the standard's controls. They do not assess GDPR legal compliance directly, though their assessment covers many areas that support compliance.
What if GDPR requirements change?
GDPR is law that can be interpreted and enforced differently over time. ISO 27701 provides a framework; you must stay current with GDPR interpretations and update your practices accordingly.
