GDPR, DORA, NIS 2, and the AI Act: how to unify your European compliance

The European digital landscape is undergoing an unprecedented transformation. For businesses, this acceleration translates into an accumulation of acronyms often perceived as disconnected constraints. Daily observation of our clients' realities reveals a worrying trend. Given the scope of DORA, NIS 2, GDPR, and the AI Act, many leadership teams feel compelled to prioritize one project at the expense of others. This choice, dictated by a lack of time and resources, often relies on a regulatory misconception. In reality, addressing these texts in isolation leads to a considerable waste of energy. An overall view reveals that by meeting the requirements of one, you lay the necessary foundations to satisfy almost all the others.

The Risk-Based Approach: the Common Denominator of All Regulations

‍

‍

The first, and arguably most fundamental, point of convergence lies in the risk management methodology. Whether it's privacy protection with GDPR, operational resilience with DORA, or network security with NIS 2, the logic is identical. Legislators no longer demand blind application of rigid rules, but rather an analysis proportionate to actual risks.

‍

An organization that has already structured its Data Protection Impact Assessment (DPIA) has already covered half the ground for the risk analysis required by the AI Act or the security audits of NIS 2. Industrializing this step involves creating a single risk repository. Rather than multiplying diagnostics, companies benefit from centralizing their asset and threat inventories, enabling cross-cutting and less costly compliance.

Third-Party Management: a Shared Foundation of Requirements Among DORA, NIS 2, and GDPR

‍

‍

Reliance on service providers has become a major focus for European regulators. DORA mandates close monitoring of technology third parties, while NIS 2 strengthens supply chain security. In parallel, GDPR requires strict guarantees from subcontractors.

‍

The alignment between these texts is striking. A well-designed vendor onboarding process can, in a single step, validate security, confidentiality, and algorithmic reliability criteria. Instead of soliciting its partners with redundant questionnaires, the company can deploy a unified evaluation framework. This administrative simplification not only reduces the internal workload but also accelerates procurement cycles and the deployment of innovative projects.

NIS 2 and DORA: a Methodology for Unified Implementation

‍

‍

The simultaneous implementation of NIS 2 and DORA presents a unique challenge. While NIS 2 broadens the scope of cybersecurity to many sectors, DORA refines these requirements specifically for the financial industry. It would be a strategic error to conduct two distinct audits when the areas of overlap exceed 80%. A convergence methodology is built upon three operational pillars.

‍

• ‍Incident Management and Reporting

NIS 2 and DORA impose very short notification deadlines for major incidents. The audit should not verify two different procedures, but rather the robustness of a single detection and alert mechanism. By testing the organization's ability to qualify an incident according to the strictest criteria, the company ensures de facto compliance for all regulators.

‍

• ‍Third-Party Resilience

The methodology involves creating a single European compliance annex. When auditing a supplier, instead of verifying compliance with NIS 2 and then DORA, the auditor validates a demanding security baseline that covers both, including audit rights and exit clauses.

‍

• ‍Robustness Tests

‍DORA introduces advanced penetration tests, while NIS 2 emphasizes the regular evaluation of security measure effectiveness. The unified audit recommends integrating NIS 2 threat scenarios into the testing campaigns required by DORA. This integration provides a granular view of vulnerability while satisfying both legislative frameworks.

Towards unified governance to escape the legislative headache

‍

‍

The major risk of this proliferation of standards is the emergence of organizational silos where each compliance officer works in isolation. To avoid this pitfall, industrialization requires implementing a common internal control framework. Documentation produced for the transparency of an artificial intelligence system can and should feed into the GDPR processing register. Similarly, the business continuity plans required by DORA directly serve the availability objectives of NIS 2.

‍

This integrated vision transforms compliance. It is no longer a series of arduous projects, but a state of permanent, fluid, and automated vigilance. The interoperability of evidence is the driver of simplification. By centralizing security policies, continuity plans, and asset registers, the organization demonstrates active control over its digital environment.

‍

‍

Multi-regulatory compliance as a driver of strategic performance

‍

‍

Ultimately, the apparent complexity of European regulations conceals a desire to create a safe and homogeneous digital space. For leaders, the challenge is no longer to endure these texts as financial burdens, but to use them as structuring guides. By streamlining efforts and identifying synergies between GDPR, DORA, NIS 2, and the AI Act, compliance becomes a simplified, predictable, and value-creating process. The question is no longer which regulation to prioritize, but how to build a foundation of trust capable of absorbing them all.

FAQ - GDPR, DORA, NIS 2, and AI Act: ksey Questions

‍

‍

What is the difference between DORA and NIS 2?

NIS 2 is a cybersecurity directive that applies to a wide range of essential sectors (energy, health, transport, digital, etc.). DORA is a sectoral regulation specifically dedicated to the financial sector, which deepens the requirements for digital operational resilience. The two texts overlap on more than 80% of their requirements, making a unified approach particularly effective for financial entities subject to both.

‍

Does the DPIA cover the requirements of the AI Act?

Partially. The Data Protection Impact Assessment (DPIA), as defined by the GDPR, shares a common logic with the risk assessment required by the AI Act for high-risk systems. A well-structured DPIA lays the groundwork for this assessment, but the AI Act introduces additional AI-specific criteria, particularly regarding algorithmic transparency, bias management, and human oversight, which must be integrated into a complementary approach.

‍

Which regulation should you start with for compliance?

It is recommended to start with the GDPR if you haven't already, as it forms the common foundation for all other regulations. Implementing a record of processing activities, a risk mapping, and a third-party management policy immediately adds value for compliance with DORA, NIS 2, and the AI Act. The goal is then to supplement this foundation with the specific requirements of each text rather than starting from scratch for each one.

‍

How can you justify a unified compliance project to management?

The financial argument is the most effective: conducting separate compliance projects for DORA, NIS 2, the GDPR, and the AI Act multiplies audit, documentation, and training costs. A unified approach allows for resource pooling, reduced administrative burden, and accelerated compliance timelines. Beyond direct savings, consolidated governance reduces the risk of cross-sanctions and strengthens the organization's credibility with its partners and clients.

‍

What are the risks of handling GDPR, DORA, NIS 2, and the AI Act in silos?

Handling these regulations in isolation exposes the organization to several cumulative risks: redundancy of efforts and team overload, inconsistencies between internal policies, undetected gaps at the intersection of the texts, and a significantly higher overall compliance cost. From a legal perspective, a violation in one area can reveal deficiencies in another during an audit, thereby multiplying exposure to sanctions.
