The protection of personal data has become an unavoidable issue for companies since the General Data Protection Regulation (GDPR) came into application in 2018. At the heart of this new regulation is a key figure: the Data Protection Officer (DPO). The DPO advises the organisation and monitors its compliance in terms of data processing, while responsibility for this compliance remains with the controller. But what exactly is the DPO’s role, and why is it essential for an organisation? In this article, we explore in depth the missions, skills, challenges and best practices for succeeding as a DPO.
What is a Data Protection Officer (DPO)?
The Data Protection Officer (DPO) is a person appointed by an organisation to ensure compliance with the laws on the protection of personal data. The DPO function was made mandatory for certain organisations under the European regulation on data protection, more commonly known as the GDPR.
Definition of the DPO under the GDPR
The GDPR defines the DPO as a professional with expertise in the field of personal data protection. The DPO’s mission is to ensure that the organisation processes data in accordance with the GDPR’s rules and other legislation in force. The DPO can be an employee of the organisation or an external consultant acting as an external DPO.
Why is the DPO function mandatory for certain companies?
Appointing a DPO is mandatory for public authorities and bodies, as well as for organisations whose core activities lead them to carry out regular and systematic monitoring of individuals on a large scale, or to process sensitive data (health data, for example) or data relating to criminal convictions on a large scale. This includes, for example, hospitals, large technology companies and financial organisations. The Commission nationale de l’informatique et des libertés (CNIL, the French data protection authority) monitors compliance with these obligations in France.
Types of companies required to appoint a DPO
Some companies must appoint a DPO because of the nature of the data processed or the scope of their operations. For example, companies operating in the following fields must appoint a DPO:
- Public sector
- Health (large-scale processing of health data)
- Technology (management of user data through digital services)
- Banking and insurance (regular and systematic monitoring of customers on a large scale, for example for credit scoring or pricing)

The DPO’s main responsibilities
The DPO takes on many responsibilities within the organisation to guarantee compliance with the regulatory framework. Here are the DPO’s main missions.
Ensuring compliance with the GDPR and other regulations
The DPO’s first mission is to ensure compliance with the European regulation on data protection. This includes monitoring data processing practices and advising on the technical and organisational measures to be implemented to ensure the security of the data.
Data protection training and awareness within the company
The DPO is also responsible for raising employees’ awareness of what is at stake in data protection and for training them in good practices. This includes training on the GDPR’s rules and the importance of data security.
Point of contact with the supervisory authorities
The DPO is the main contact for supervisory authorities such as the CNIL in France. The DPO must be ready to respond to any request from these authorities and to ensure the ongoing compliance of the company’s data processing operations.
Coordination with internal and external stakeholders
Finally, the DPO works with various stakeholders, both internal (IT teams, CISO, legal department) and external (partners, subcontractors), to guarantee that data is processed in accordance with the GDPR’s rules.

The key skills of a good DPO
A Data Protection Officer must have a varied set of skills, ranging from knowledge of the laws to the management of cybersecurity.
Expertise in data protection and law
The DPO must be an expert in the laws on the protection of personal data, in particular the GDPR, and understand the legal obligations that flow from them.
Skills in cybersecurity management and risk management
IT security is a major issue for the DPO, who must work in close collaboration with the CISO (Chief Information Security Officer). The DPO must ensure that data is secured and that security incidents are managed.
Communication and teaching skills
The DPO must have strong communication skills in order to explain complex concepts to non-technical teams and to work with internal and external stakeholders.
Why the DPO’s role is crucial for GDPR compliance
Fines and penalties for non-compliance
Failure to comply with the GDPR can lead to fines of up to 4% of the company’s annual worldwide turnover. The DPO therefore has an essential mission in avoiding these penalties and guaranteeing legal compliance.
Protecting the company’s reputation
Data breaches can seriously damage a company’s reputation. By making sure that the data of customers and employees is protected, the DPO helps to preserve the organisation’s brand image.
Guaranteeing the security of personal data
The DPO ensures the protection of personal data and the compliance of processing operations. The DPO is therefore a key element of the company’s cybersecurity.
How to become a Data Protection Officer?
The path to becoming a DPO is not a linear one. However, several elements are essential for entering this profession.
Academic background and recommended qualifications
A degree in law, IT or cybersecurity is often recommended for moving into a DPO position. In France, some universities offer specialised master’s degrees in data protection or cybersecurity.
Relevant certifications for a DPO
Certifications such as CIPP/E (Certified Information Privacy Professional/Europe) or ISO 27001 Lead Implementer can strengthen a DPO’s legitimacy and expertise.
Experience needed to excel as a DPO
In order to be effective, a DPO must also have solid professional experience, preferably in fields related to data protection, IT security or law.

Common challenges for a DPO
The DPO’s job is demanding and involves several challenges.
Lack of resources or suitable tools
Many companies do not have the necessary resources or suitable tools to enable the DPO to carry out their missions. Software such as Make IT Safe can, however, make compliance easier.
Keeping up with changes in legislation and in data protection practices
Laws and practices in the field of data protection evolve quickly. The DPO must be kept constantly informed of new developments.
Managing collaboration between legal, IT and business teams
Data protection concerns several departments within a company. The DPO must coordinate actions smoothly so as to avoid conflicts of interest and to guarantee compliance.
Data Protection Officer salary: how much does a DPO earn?
A DPO’s salary varies according to experience, the size of the company and the business sector.
Factors influencing a DPO’s salary
- Company size: large companies generally offer higher pay.
- Sector: companies in heavily regulated sectors (banking, health) offer higher pay.
- Experience: a junior DPO will earn less than an experienced DPO.
Salary range by country and level of experience
In France, a junior DPO can expect a gross annual salary of 40,000 to 50,000 euros, while an experienced DPO can earn between 60,000 and 100,000 euros, or even more in some cases.
Best practices for an effective DPO
A high-performing DPO follows certain best practices to ensure the organisation’s compliance.
Setting up a structured compliance plan
It is important to develop a compliance plan based on the rules of the GDPR and other applicable laws. This plan must include regular audits and training.
Regularly auditing data processing operations
A regular audit of data processing practices makes it possible to identify weaknesses and correct them before they lead to incidents.
Establishing effective collaboration with the CISO and IT teams
Good communication between the DPO, the CISO and IT is crucial to guarantee data security and compliance with cybersecurity standards.
Keeping rigorous documentation
Clear and rigorous documentation of data processing operations and of the actions taken is essential to prove the company’s compliance in the event of an inspection.
The link between the DPO and cybersecurity
Both the DPO and the CISO (Chief Information Security Officer) play roles that complement each other.
How cybersecurity and data protection complement each other
Data protection cannot be ensured without a solid cybersecurity framework in place. The DPO therefore works in close collaboration with the security teams in order to protect personal data against cyberattacks.
The DPO’s role in managing security incidents
In the event of a data breach, the DPO must act quickly to limit the damage, in collaboration with the CISO. The DPO oversees the mean time to respond (MTTR) and ensures that the right methods are followed.

How to choose the right DPO for your company
The choice of a DPO can have a major impact on a company’s compliance.
In-house or outsourced: advantages and disadvantages
Some companies choose to keep the DPO function in-house, while others prefer to outsource this function for greater flexibility.
Criteria for selecting a good DPO
- Solid technical and legal skills
- Experience in cybersecurity and risk management
- Communication skills to work with non-technical colleagues

The DPO is a key player in the protection of personal data and GDPR compliance. As well as ensuring data security, the DPO plays a crucial role in the company’s cybersecurity and in the management of regulatory risks. A good DPO must have technical, legal and managerial skills, and rely on suitable tools to carry out their missions effectively. For companies that wish to comply with the regulations in force, appointing a competent Data Protection Officer is essential.
