Navigating Large-Scale Data Breaches in the EEA: Leveraging the 'One-Stop-Shop' Mechanism for Global Companies

As businesses expand and operate across borders, the complexities of managing data breaches increase significantly. A global company dealing with a large-scale data breach that affects individuals in multiple European Economic Area (EEA) countries faces intricate reporting obligations under the General Data Protection Regulation (GDPR). One powerful tool to simplify this process, for companies with a main establishment within the EEA, is the One-Stop-Shop (OSS) mechanism.

Understanding the One-Stop-Shop (OSS) Mechanism

The OSS mechanism allows companies engaged in cross-border data processing within the EEA to streamline their interactions with Data Protection Authorities (DPAs). Instead of dealing with multiple DPAs across different countries, a company can interact with a single Lead Supervisory Authority (LSA). The LSA is typically the DPA in the country where the company has its main establishment or central administration in the EEA. Conversely, companies without main establishments in the EEA cannot rely on the OSS and will need to notify the DPA in every EEA country where affected individuals reside.

What constitutes a 'main establishment' in this context? The European Data Protection Board (EDPB), a body consisting of representatives from DPAs in the EEA Member States, explains that such an establishment is the place of central administration of the company in the EEA and must:

1. make decisions regarding the purposes and means of personal data processing in the EEA, and
2. have the authority to implement these decisions.?

If such decision-making and implementation powers are outside the EEA, the entity cannot be considered a main establishment.

For example, if a company’s European headquarters are in The Netherlands, the Autoriteit Persoonsgegevens(AP) would act as the LSA, coordinating with other concerned DPAs across the EEA. This approach simplifies the reporting process, ensuring consistency and efficiency in handling the breach.

Practical Steps for Handling Large-Scale Data Breaches Using the One-Stop-Shop (OSS) Mechanism

In addition to the other steps identified in this article on how to respond to a data breach, the following steps will be handy when addressing a breach that involves cross-border data processing:

1. Identify the Lead Supervisory Authority (LSA): Determine which DPA will serve as your LSA based on your main establishment within the EEA. This will be your primary point of contact for the breach reporting. If you have any doubt as to the identity of your LSA, then you should, at a minimum, notify the local DPA where the breach has taken place.
2. Immediate Containment and Assessment: Once a breach is identified, immediately contain it and assess the extent of the damage. This involves stopping further data loss, identifying affected data, and determining the cause of the breach.
3. Report to the LSA: Notify your LSA within 72 hours of becoming aware of the breach. Your report should include: the nature of the breach, the categories and approximate number of individuals affected, the potential consequences of the breach, and the measures taken or proposed to address the breach.
4. Coordinate with Other DPAs: The LSA will coordinate with other concerned DPAs in the EEA, ensuring a unified approach. Be prepared to provide additional information as requested by your LSA, which will liaise with other authorities.

Scale-Ups Expanding Internationally: Take Note

For growing scale-ups expanding into international markets, understanding and utilizing the OSS mechanism is crucial. As your operations span multiple countries, being able to streamline breach reporting through a single LSA can save time, reduce administrative burden, and ensure compliance across the EEA. Establishing robust internal processes for managing cross-border data processing activities and familiarizing yourself with the role of LSAs in your operating regions can facilitate smoother communication and quicker resolutions in the event of a data breach. However, even with such robust internal processes set up to implement the OSS mechanism, companies should still be prepared for scenarios where they have to notify multiple regulators within and outside of Europe.

Conclusion

To efficiently navigate the complexities of GDPR compliance in the event of a large-scale data breach, businesses should consider developing a simple, yet effective plan to utilize the OSS mechanism. Start by identifying your Lead Supervisory Authority and establishing clear protocols for breach reporting and coordination. By doing so, you ensure that your company can respond swiftly and compliantly, minimizing the impact of any data breaches on your operations and reputation.
