GDPR GDPR-Art.28: Processor

Use only processors providing sufficient guarantees to implement appropriate technical and organisational measures such that the processing meets the Regulation's requirements and protects the rights of the data subject. A processor must not engage another processor without the controller's prior specific or general written authorisation, and under a general authorisation must inform the controller of intended additions or replacements so the controller can object. The processing must be governed by a written contract or other legal act binding the processor to the controller, setting out the subject matter and duration, the nature and purpose, the type of personal data, the categories of data subjects and the controller's obligations and rights, and stipulating that the processor processes only on documented controller instructions including as to transfers, ensures persons authorised to process are under a duty of confidentiality, takes all Article 32 measures, respects the sub-processor conditions, assists the controller in responding to data subject rights requests, assists with Articles 32 to 36, deletes or returns all personal data at the controller's choice at the end of the service and deletes existing copies unless law requires retention, and makes available all information needed to demonstrate compliance and allows for and contributes to audits and inspections. The processor must immediately inform the controller if it considers an instruction infringes data protection law. The same obligations must be imposed on any sub-processor, and the initial processor remains fully liable for the sub-processor's performance. A processor that determines purposes and means is a controller for that processing.
