The primary function of a data protection officer (DPO) in organizations is to ensure compliance with data protection laws and regulations, such as GDPR. The DPO oversees data handling practices, assesses data processing activities, and serves as a point of contact for data subjects and regulatory authorities. They are responsible for educating staff about data protection policies, conducting audits, and advising on data-related risks. Their role is crucial in protecting individuals' privacy and safeguarding organizational data.
