Our Verdict
ISO 27701 and GDPR serve fundamentally different purposes but are highly complementary. ISO 27701 provides a structured management system framework for privacy operations, while GDPR defines the legal requirements for data protection. ISO 27701 certification does not automatically mean GDPR compliance, but it demonstrates organizational accountability and provides a systematic approach to meeting privacy obligations.
ISO 27701 is particularly valuable as a tool for demonstrating GDPR's accountability principle. The standard's structured approach to privacy management, including risk assessment, documented policies, and continuous improvement cycles, maps well to many GDPR requirements. Organizations pursuing ISO 27701 certification will find that much of the groundwork supports their GDPR compliance efforts.
For organizations looking to build a robust privacy program, combining ISO 27701's management system approach with GDPR's legal requirements creates a comprehensive framework. ComplyIQ can help organizations map ISO 27701 controls to GDPR requirements and track compliance with both frameworks in an integrated manner.
Frequently Asked Questions
Does ISO 27701 certification mean I am GDPR compliant?
No, ISO 27701 certification does not equal GDPR compliance. ISO 27701 provides a management system framework that supports many GDPR requirements, but GDPR has specific legal obligations like lawful processing bases, specific individual rights, and cross-border transfer mechanisms that go beyond what ISO 27701 addresses. Certification is evidence of good practice but not legal compliance.
Do I need ISO 27001 before ISO 27701?
Yes, ISO 27701 is an extension to ISO 27001 and requires an existing ISO 27001 information security management system as a prerequisite. You need to be ISO 27001 certified or pursuing certification before you can implement ISO 27701.
Can ISO 27701 help with GDPR accountability?
Yes, significantly. GDPR Article 5(2) requires organizations to demonstrate compliance through accountability. ISO 27701 certification provides evidence of a systematic approach to privacy management, documented policies and procedures, regular risk assessments, and continuous improvement, all of which support the accountability principle.
Is ISO 27701 recognized by GDPR supervisory authorities?
While ISO 27701 is not formally recognized as a GDPR certification mechanism under Article 42, supervisory authorities generally view it positively as evidence of organizational accountability and good privacy practices. It can be particularly useful during regulatory investigations or when demonstrating compliance efforts.
Which should I pursue first?
GDPR compliance should be the priority if you process EU resident data, as it is a legal obligation with enforcement consequences. ISO 27701 can then be pursued as a complementary framework to strengthen and formalize your privacy management system. The structured approach of ISO 27701 can also help identify and address gaps in your GDPR compliance program.
