DPA

What is DPA?

DPAA Data Processing Agreement is the binding contract required by GDPR Article 28 between a data controller and processor when personal data is processed on the controller's behalf.


A Data Processing Agreement (DPA) is the written contract required by Article 28 of the EU General Data Protection Regulation (Regulation 2016/679) whenever a controller engages a processor to handle personal data on its behalf. It must specify the subject-matter, duration, nature and purpose of the processing, the categories of data and data subjects, and the controller's instructions. The DPA must impose obligations to process only on documented instructions, ensure confidentiality, implement appropriate security measures (Art. 32), assist with data-subject rights and breach notification, allow audits, address sub-processor engagement, and govern return or deletion of data at the end of services. Similar duties exist under the UK GDPR and many non-EU laws (LGPD, CPRA, PIPEDA).
