What is a DPO? (Data Protection Officer) & Do You Need One?

An illustration of a professional representing a Data Protection Officer (DPO) guiding a business.

The Data Protection Officer (DPO) is a key figure in the GDPR framework. This individual is responsible for overseeing a company's data protection strategy and ensuring its compliance with the regulation. For many organizations, appointing a DPO is not just a best practice—it's a legal requirement.

If you're wondering what a DPO actually does and whether your business needs one, this guide will provide the clarity you need.

The Role and Responsibilities of a DPO

A DPO is a knowledgeable expert on data protection law and practices. Their primary function is to advise the organization on its data protection obligations. Their key responsibilities include:

  • Informing and advising: Educating employees and management on GDPR and related data protection laws.
  • Monitoring compliance: Overseeing the organization's adherence to GDPR and internal data protection policies.
  • Liaising with the supervisory authority: Acting as a contact point for the relevant data protection authority.
  • Being a point of contact for individuals: Handling all queries and requests from users regarding their personal data.
  • Conducting Data Protection Impact Assessments (DPIAs): Advising on and monitoring the performance of DPIAs when a new data processing activity is planned.

When is a DPO Mandatory?

Under Article 37 of the GDPR, an organization must appoint a DPO if it meets any of the following criteria:

  • Public Authority or Body: You are a public authority or body (excluding courts acting in their judicial capacity).
  • Large-Scale Systematic Monitoring: Your core activities involve large-scale, regular, and systematic monitoring of individuals. This often applies to companies using online behavioral advertising or location tracking.
  • Large-Scale Processing of Special Categories of Data: Your core activities involve large-scale processing of special categories of data (e.g., health data, political opinions) or data relating to criminal convictions and offenses.

Even if you don't meet these specific criteria, appointing a DPO is still considered a best practice for demonstrating accountability and building user trust.

DPO Requirements and Qualifications

The GDPR outlines specific requirements for a DPO:

  • Expertise: They must have expert knowledge of data protection law and practices.
  • Independence: The DPO should be able to perform their duties with a degree of autonomy and not be told how to do their job.
  • No Conflict of Interest: Their role should not conflict with other duties (e.g., a CEO or Head of Marketing should not also be the DPO).

A DPO can be an internal employee or an external consultant. This flexibility allows small businesses to outsource the role to a specialized firm.
