ISO 27701 and GDPR both support privacy protection, but they are not the same.
GDPR is a privacy regulation that defines legal requirements for protecting personal data of EU residents.

ISO 27701 is an international privacy management standard that helps organizations build a structured framework for managing privacy information, risks, policies, controls, and accountability.
In simple terms:

GDPR tells organizations what they must comply with.
ISO 27701 helps organizations build the system to manage privacy effectively.

Understanding the difference is important for privacy teams, compliance professionals, auditors, and organizations working toward stronger data protection practices.
