Which entity is typically responsible for ensuring data processors comply with the GDPR?

The entity typically responsible for ensuring data processors comply with the General Data Protection Regulation (GDPR) is the data controller. According to the GDPR principles, the data controller is the person or organization that determines the purposes and means of processing personal data. As part of their responsibilities, data controllers must ensure that any data processors they engage with comply with the requirements set out in the regulation. This includes establishing contracts that outline the terms of data handling and ensuring that processors implement appropriate technical and organizational measures to protect personal data.

While compliance authorities and information officers may play roles in the broader context of data protection and oversight, it is primarily the data controller that holds the legal responsibility for ensuring compliance with the GDPR concerning their data processors. This relationship is crucial because if a data processor fails to comply, the data controller can still be held accountable under the regulation.
