Personal-data protection has become an unavoidable stake for companies since the GDPR (General Data Protection Regulation) came into force in 2018. At the heart of this regulation sits a key figure: the Data Protection Officer (DPO). The DPO is the guarantor of company compliance when it comes to data processing. But what exactly is the DPO’s role, and why is it essential? This article explores in depth the missions, skills, challenges and best practices to succeed 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 personal-data protection laws. The DPO function became mandatory for certain organisations under the European GDPR.
GDPR definition of the DPO
The GDPR defines the DPO as a professional with expertise in personal-data protection. Their mission is to ensure the organisation processes data in line with GDPR rules and other applicable laws. 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 bodies and companies processing personal data at scale or sensitive data such as health or financial information. This includes hospitals, major technology companies and financial organisations. The CNIL (French data protection authority) monitors compliance in France.
Types of company required to appoint a DPO
Some companies must appoint a DPO because of the nature of the data processed or the scale of operations:
- Public sector
- Health (large-scale health-data processing)
- Technology (managing user data across digital services)
- Banking and insurance (sensitive financial-data management)
Main responsibilities of the DPO
The DPO takes on many responsibilities to guarantee compliance with the regulatory framework.
Ensure GDPR and regulatory compliance
The DPO’s first mission is to oversee personal-data protection compliance. This includes supervising data-processing practices and implementing technical and organisational measures to guarantee their security.
Training and awareness inside the company
The DPO also raises employee awareness on data-protection stakes and trains them on best practices — including training on GDPR rules and the importance of data security.
Point of contact with supervisory authorities
The DPO is the main contact for supervisory authorities such as the CNIL in France. They must be ready to answer any request from these authorities and ensure continuous compliance of the company’s data-processing processes.
Coordination with internal and external stakeholders
Finally, the DPO collaborates with various stakeholders — internal (IT teams, CISO, legal) and external (partners, subcontractors) — to guarantee data is processed in line with GDPR rules.
Key skills of a good DPO
A DPO must have varied skills, from legal knowledge to cybersecurity management.
Data-protection and legal expertise
The DPO must be an expert on personal-data protection laws — particularly the GDPR — and understand the legal obligations they create.
Cybersecurity and risk-management skills
IT security is a major stake for the DPO, who must work closely with the CISO. They must oversee data security and security-incident management.
Communication and pedagogy
The DPO needs strong communication skills to explain complex concepts to non-technical teams and collaborate with internal and external stakeholders.
Why the DPO’s role is crucial for GDPR compliance
Fines and penalties for non-compliance
GDPR non-compliance can trigger fines of up to 4% of the company’s global annual turnover. The DPO has an essential mission to avoid these penalties and guarantee legal compliance.
Protecting the company’s reputation
Data breaches can severely damage a company’s reputation. By ensuring customer and employee data is protected, the DPO helps preserve the organisation’s brand image.
Guarantee personal-data security
The DPO oversees personal-data protection and the compliance of processing activities. They are a key part of the company’s cybersecurity.
How to become a Data Protection Officer
The path to becoming a DPO is not linear, but several elements are essential.
Academic background and recommended qualifications
A degree in law, IT or cybersecurity is often recommended. In France, some universities offer specialised masters 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
To be effective, a DPO needs solid professional experience, ideally in fields tied to data protection, IT security or law.
Common challenges for a DPO
The DPO job is demanding and comes with several challenges.
Lack of resources or adapted tools
Many companies lack the resources or proper tools to let the DPO fulfil their missions. Software like Make IT Safe eases compliance.
Following legislative and practice changes
Data-protection laws and practices evolve fast. The DPO must stay informed of new developments.
Managing collaboration between legal, IT and business teams
Data protection involves multiple departments. The DPO must coordinate actions smoothly to avoid conflicts of interest and guarantee compliance.
DPO salary: what does a DPO earn in 2024?
A DPO’s salary varies with experience, company size and sector.
Factors influencing a DPO’s salary
- Company size: large companies generally offer higher pay.
- Sector: heavily regulated sectors (banking, health) pay more.
- Experience: a junior DPO earns less than a senior DPO.
Salary range by country and experience level
In France, a junior DPO can expect a gross annual salary of €40,000 to €50,000, while a senior DPO can earn between €60,000 and €100,000, sometimes more.
Best practices for an effective DPO
A high-performing DPO follows certain best practices.
Set up a structured compliance plan
Develop a compliance plan based on GDPR and other applicable laws. The plan must include regular audits and training.
Audit data-processing processes regularly
A regular audit of data-processing practices surfaces gaps and fixes them before they lead to incidents.
Effective collaboration with the CISO and IT teams
Good communication between DPO, CISO and IT is crucial to guarantee data security and compliance with cybersecurity standards.
Keep rigorous documentation
Clear, rigorous documentation of data-processing processes and actions taken is essential to prove compliance during audits.
The link between the DPO and cybersecurity
The DPO and the CISO play complementary roles.
How cybersecurity and data protection complement each other
Data protection cannot be ensured without strong cybersecurity. The DPO works closely with security teams to protect personal data against cyberattacks.
DPO’s role in security-incident management
When a data breach happens, the DPO must intervene quickly to limit damage — in collaboration with the CISO. They oversee the Mean Time To Respond (MTTR) and ensure the right methods are respected.
How to choose the right DPO for your company
Choosing a DPO can have a major impact on compliance.
Internal or external: pros and cons
Some companies internalise the DPO function; others outsource it for more flexibility.
Criteria to select a good DPO
- Strong technical and legal skills
- Cybersecurity and risk-management experience
- Communication skills to collaborate with non-technical employees
The DPO is a key actor in personal-data protection and GDPR compliance. Beyond ensuring data security, they play a crucial role in company cybersecurity and regulatory risk management. A good DPO must have technical, legal and management skills and rely on adapted tools to carry out their missions effectively. For companies that want to meet applicable regulations, appointing a competent Data Protection Officer is essential.
