A Data Protection Officer (DPO) assists you to monitor internal compliance, informs and advises you on your data protection obligations, provides advice regarding Data Protection Impact Assessments (DPIAs), and acts as a contact point between data subjects and the supervisory authority.
A DPO also serves as the point of contact between the company and any Supervisory Authorities (SAs) who oversee activities related to data processing. It is recommended that every organization has a DPO.
