Data Protection Officer (DPO) in France: A Complete Guide by a Lawyer for SME Managers and CEOs

As an SME manager, you deal with the personal data of your customers, suppliers and employees on a daily basis. The data protection officer, or DPO, appears to be an essential pillar for complying with the GDPR and avoiding costly sanctions. This comprehensive article explains step-by-step how to integrate this strategic function into your organization.

What is a Data Protection Officer (DPO)?

The Data Protection Officer (DPO) is a key figure introduced by the General Data Protection Regulation (GDPR), applicable since 2018. He is an independent expert responsible for ensuring compliance with personal data protection rules within your SME. Unlike a simple consultant, the DPO has a protected status: he cannot be dismissed for the exercise of his missions and enjoys total independence.

Imagine an SME like yours, specialized in e-commerce, which collects the email addresses and bank card numbers of thousands of customers. Without a DPO, a simple incident — such as a data leak via a poorly secured email — exposes you to a fine of 20 million euros or 4% of global turnover. The DPO anticipates these risks by auditing your processes from the start.

Educational framework: The GDPR in figures for SMEs

• More than 300,000 French companies have appointed a DPO since 2018.
• Cumulative fines by the CNIL: more than 100 million euros in 2024, including 40% affecting SMEs for lack of compliance.
  These figures highlight the urgency for leaders like you to prioritize this nomination.

Does a DPO have to be a lawyer?

No, the RGPD does not require that data protection officer be a lawyer. Article 39 of the GDPR simply requires the DPO to have professional expertise in law and data protection, as well as a thorough knowledge of the company's business sectors. A certified IT engineer or a specialized lawyer may be a perfect fit.

However, for an SME facing complex litigation, a DPO lawyer provides a decisive advantage. It combines detailed legal analysis and strategic advice, especially in the event of a CNIL control or litigation. Take the example of a Parisian tech SME: its DPO, a lawyer, successfully defended a data breach complaint by demonstrating a data protection impact assessment (AIPD) beforehand, avoiding a penalty of 150,000 euros.

In practice, law professors such as those at Paris-Dauphine University insist on this versatility: a non-lawyer DPO manages the operational side, but a lawyer excels in Privacy by design, integrating data protection right from the design of your digital tools.

Who can be a data protection officer?

Any qualified profile can work as DPO, internal or external. The GDPR (article 37) provides for three mandatory cases of appointment:

• Large-scale processing of sensitive data (health, political opinions).
• Systematic and regular surveillance of people (extended video surveillance).
• Public authorities or main public entities.

For your SME, even without a legal obligation, appointing a DPO is still recommended if you process data from more than 5,000 people per year. Concrete example : An artisanal bakery in Lyon manages customer files via CRM software. Its external DPO, a certified consultant, identified gaps in consent, leading to a redesign of compliant online forms.

The DPO can be:

• An internal employee, hierarchically independent.
• An external service provider, such as a RGPD law firm in Paris.
• A lawyer specialized in cybersecurity lawyer, combining RGPD and IT security.

What are the missions of a GDPR lawyer as a DPO?

One RGPD lawyer acting as DPO fulfills the classic missions of the RGPD (article 39), with increased legal expertise. Its main tasks include:

• Informing and advising the manager and employees on RGPD obligations.
• Supervise compliance, through internal audits and AIPD.
• Raise awareness via training courses adapted to your SME.

Concrete example : In a logistics SME in Paris, the DPO lawyer carried out a mapping of treatments, revealing that the GPS data of the deliverers was not anonymized. Result: implementation of a data minimization clause, avoiding a collective complaint.

Professors like Marie-Anne Frison-Roche emphasize the importance of Privacy by design : incorporate protection by design. For a lawyer, this means drafting precise contractual clauses.

Example of a standard clause (from CNIL guides):
“The Subcontractor is committed to implementing measures of Privacy by design and Privacy by default, in particular by anonymizing non-essential data and limiting access. Any secondary subcontracting requires the prior written consent of the Data Controller.”

Detailed missions of the data protection officer

The DPO guides you on the rights of individuals (access, correction, forgetting). For an SME, this means training your sales teams to obtain valid consent during email prospecting.

Jurisprudential case : CJEU, “Fashion ID” case (C-40/17), where a Facebook plugin was deemed co-responsible without prior consent. Your lawyer DPO anticipates this by reviewing your websites.

Overseeing audits and AIPD

THEdata protection impact assessment is mandatory for high-risk treatments. The DPO assesses, for example, the use of AI to score the customers of a retail SME.

Practical steps :

• Identify risks (flight, discrimination).
• Consult with stakeholders.
• Suggest measures (AES-256 encryption).

Cooperate with the CNIL and manage incidents

In the event of a violation (e.g.: ransomware affecting your customer databases), the DPO notifies the CNIL within 72 hours. A DPO lawyer excels here, because he also manages the cybersecurity lawyer, linking RGPD to the military programming law.

example : A publishing SME suffered a breach in 2024; its DPO limited the damage to a €50,000 fine thanks to a rapid notification.

Awareness-raising and continuing education

Monthly workshops for your teams: “How to manage a request for access to data from an unhappy customer?”. Lawyers like those at the Paris Bar integrate simulations of DGCCRF controls.
