Europol and Eurojust do not have executive tasks, but support the work of the police and judicial authorities in the EU Member States. In doing so, Europol and Eurojust collect and analyse large amounts of information, often of a personal nature, about suspects, convicted persons, witnessess and victims of crime. This personal data processing is subject to independent supervision.

The European Public Prosecutor's Office (EPPO) is an independent body of the EU, which is authorised to investigate, prosecute and take to court punishable offences that adversely affect the EU budget (such as fraud, corruption and serious cross-border VAT fraud). In doing so, the EPPO processes personal data. This personal data processing is also subject to independent supervision.
