Which body oversees compliance with GDPR?

The body that oversees compliance with the General Data Protection Regulation (GDPR) is the Data Protection Authorities in each EU member state. Each member state in the European Union is responsible for establishing its own independent supervisory authority, which ensures that the provisions of GDPR are properly enforced and that individuals' data protection rights are upheld.

These authorities have several important functions, including investigating complaints made by individuals, conducting audits and inspections of organizations processing personal data, and issuing fines for non-compliance. Additionally, they play a crucial role in advising the government on data protection matters and helping to promote public awareness about data privacy rights.

The other options do not have oversight responsibilities concerning GDPR. The International Data Security Association, for instance, is not a regulatory or supervisory body for GDPR compliance. The Federal Trade Commission in the U.S. primarily addresses issues related to consumer protection and competition, but it does not enforce GDPR as it is specific to European Union regulations. The Global Data Privacy Council does not exist as an official governing body for GDPR compliance. Thus, the role of the Data Protection Authorities is crucial in ensuring that GDPR is applied uniformly across the EU.
