Data protection authorities (DPAs) represent one of the key actors, not only when it comes to the execution of privacy and data protection policies, but also in terms of awareness raising, consultancy and networking. Since they comprise the spearhead of regulators in the field of privacy and data protection regulation, their independence from the private as well as political domain becomes of the utmost importance.
