What is the role of a data controller?

A data controller is responsible for determining the purposes for which personal data is processed, as well as the means of processing that data. This role includes ensuring that the processing of data complies with relevant data protection laws and regulations, such as the General Data Protection Regulation (GDPR) in Europe.

The data controller must establish policies and procedures for data handling, maintain oversight of data usage, and ensure that individuals' rights are protected in relation to their personal data. This encompasses accountability for data security, data accuracy, and providing transparency to individuals about how their data is used.

In contrast, while cybersecurity measures are crucial and can be part of the controller’s responsibilities, they do not define the role of the data controller itself. Handling marketing and promotions can involve the processing of data, but it is not the primary function of a data controller. Operating data storage facilities is also a separate function that might involve data processors or IT teams, rather than the controller, as they focus on the strategic oversight of data management rather than the physical aspects of data storage.
