Which organization is typically responsible for enforcing "do not process" regulations?

The role of enforcing "do not process" regulations primarily falls to data protection authorities. These authorities are tasked with overseeing the implementation and compliance with laws that protect individuals' data rights, such as the General Data Protection Regulation (GDPR) in Europe or similar legislation in other jurisdictions.

Data protection authorities have the power to investigate complaints, conduct audits, and impose penalties on organizations that fail to adhere to regulations concerning personal data processing. They help ensure that individuals can exercise their rights regarding their personal data, including the rights to access, rectify, delete, or object to processing.

While internal compliance teams may establish internal policies in line with regulations, they do not possess the external regulatory power held by data protection authorities. Similarly, marketing departments and human resources may work with data but are not responsible for enforcing compliance at the regulatory level. Thus, the enforcement authority is distinctly reserved for data protection authorities, making them the correct answer.
