The role of a data protection officer (DPO) is to ensure that an organization complies with data protection laws and regulations like the GDPR. The DPO is responsible for overseeing data protection strategies, conducting audits, and providing guidance on data processing activities. They serve as a point of contact between the organization and data protection authorities. The DPO also raises awareness of data privacy practices and ensures that all employees are trained on compliance matters, thereby safeguarding personal data and maintaining consumer trust.
