What is a Data Protection Officer?
A Data Protection Officer (DPO) is an independent official who oversees compliance with the General Data Protection Regulation (GDPR) within an organization. The role is defined in articles 37 through 39 of the GDPR and has been applicable in all EU member states since May 25, 2018.
The DPO is not in the management hierarchy but reports directly to the highest governing body of the organization. This is no accident: the GDPR requires that the DPO be completely independent in performing their duties. The officer cannot be dismissed or disadvantaged because of performing their duties. In practice, this means the DPO must also be able to provide negative advice without career risk.
When is a DPO legally mandatory?
The GDPR (Article 37) mandates appointing a DPO in three situations:
- Public authorities and public law bodies: With the exception of courts exercising judicial functions. This includes municipalities, ministries, implementation agencies, supervisory authorities and public law legal entities.
- Systematic monitoring on a large scale: Organizations that systematically monitor individuals on a large scale as a core activity. Think of companies that perform location tracking, camera surveillance, behavioral advertising profiling or financial credit scoring.
- Processing of special categories on a large scale: Organizations that process special personal data on a large scale as a core activity—data about health, race or ethnic origin, political opinions, religious beliefs, sexual orientation, biometric data, criminal records or genetic data.
The term "large scale" is not exactly defined in the GDPR. The European Data Protection Board (EDPB) considers factors such as the number of affected persons, the geographic scope, the duration and frequency of processing, and the volume of data processed. A medical practice maintaining health records of its own patients probably does not need to appoint a DPO; a hospital chain processing millions of patient records certainly must.
When is a DPO strongly recommended?
Beyond legal requirements, a DPO is strongly recommended for any organization that processes substantial personal data. The Data Protection Authority advises appointing a DPO when an organization:
- Processes personal data of employees, customers or contacts on a scale that carries risks
- Must regularly conduct Data Protection Impact Assessments (DPIAs)
- Shares data with many external parties
- Processes data outside the EU/EEA
The core tasks of a DPO
The GDPR (Article 39) explicitly describes the core tasks of a DPO:
Inform and advise: The DPO informs and advises the organization, its staff and management about their obligations under the GDPR and other privacy legislation. This includes providing legal advice on new processing activities, marketing campaigns, systems and contracts.
Monitor compliance: The DPO monitors GDPR compliance, including overseeing tasks, staff awareness and training, and conducting audits.
Advice on DPIAs: The DPO advises on the conduct of Data Protection Impact Assessments (DPIAs) and monitors their implementation. A DPIA is mandatory for processing that is likely to pose a high risk to data subjects.
Contact point for the authority: The DPO is the contact point for the Data Protection Authority. All formal communication with the supervisory authority goes through the DPO. This also includes cooperation in investigations and responding to authority inquiries.
Handle data subject requests: The DPO coordinates handling requests from individuals exercising their rights: access, rectification, deletion, restriction of processing, portability and objection. Organizations must respond to such requests within one month.
DPO requirements: education and certification
The GDPR sets no formal educational requirements for a DPO but requires "expertise in the law and practice concerning data protection" and knowledge of the organization's operational sector. In practice, two certifications are considered the gold standard:
- CIPP/E (Certified Information Privacy Professional/Europe) of the IAPP (International Association of Privacy Professionals): internationally recognised, substantively strong, highly sought after by larger organisations and multinationals
- EXIN Privacy and Data Protection Professional: Netherlands-based, recognised by the authority, well-suited for the local market and government organisations
In addition to legal knowledge, an effective DPO also needs practical skills: stakeholder management, the ability to explain complex matters in understandable terms to non-experts, and organizational insight to embed compliance in daily processes.
Registration with the Data Protection Authority
Organizations for which a DPO is mandatory are legally required to register the DPO's name and contact details with the Data Protection Authority. This applies to both internal and external DPOs. Registration is simple via the authority's portal. The DPO's contact details must also be made public—on the organization's website and in the privacy statement.
Internal versus external DPO: what fits your organization?
An internal DPO is an employee of the organization. Advantages: familiarity with the organization, quick availability, involvement in daily decision-making. Disadvantages: the GDPR requirement for independence can create tensions, replacement during illness or departure is difficult, and broad expertise is expensive for a full-time position.
An external DPO is a certified specialist who fulfills the DPO role on a part-time basis for multiple clients. This offers structural advantages: no hiring costs for a full-time role, immediate availability of specialist expertise, no conflicting interests with internal career concerns, and easier replacement. For SME organizations, external DPO services are virtually always the practical and cost-effective choice.
iso2700x.com offers external DPO services for organizations that need a certified DPO but do not have the need or size for a full-time internal appointment. Our DPOs are CIPP/E certified and combine privacy expertise with deep knowledge of information security—a combination that is rare and valuable in the market.
