Who is responsible for a GDPR data breach?

Under GDPR, the responsibility for data breaches is a joint effort between data controllers and processors. Controllers takes the lead in protecting personal data and are required to let both the relevant supervisory authority and the individuals involved know if a breach happens. Processors, who manage data on behalf of the controllers, have their security measures in place and must notify the controller immediately if there’s a problem. Supervisory authorities ensure that everyone is playing by the rules, investigating any breaches and enforcing penalties when needed, making sure both parties uphold the required data protection standards.
