Storing Customer Data Abroad: What Is Prohibited
For an SME or a tradesperson, storing customer data abroad may seem like a practical solution, especially in the era of cloud computing and digitalization. However, this decision raises major legal issues, particularly with the GDPR. The key term here is clear: customer data abroad GDPR. Ignoring these rules exposes your business to severe penalties, fines, or even a loss of customer trust. How can you navigate between legal obligations, risks, and suitable solutions? This article guides you step-by-step to secure your data while remaining compliant, without compromising the efficiency of your operations.
Discover what is prohibited, legal alternatives, and best practices to protect your business and your customers, no matter where you are.
Why Storing Customer Data Abroad Raises GDPR Issues
Storing customer data abroad presents significant challenges under the GDPR, primarily due to strict requirements for data protection and sovereignty. The General Data Protection Regulation (GDPR) mandates that any personal information collected from European residents must be processed in compliance with high standards, regardless of where it is stored. However, transferring this data outside the EU without adequate safeguards exposes businesses to legal and financial risks.
First, the GDPR requires that third countries provide a level of protection “essentially equivalent” to that of the European Union. Only a few countries, such as Switzerland or Canada, benefit from official recognition by the European Commission. For other destinations, like the United States, transfers are permitted only under strict conditions, through mechanisms such as Standard Contractual Clauses (SCCs) or Binding Corporate Rules (BCRs). Without these measures, storing customer data abroad under the GDPR becomes illegal, with penalties potentially reaching 4% of global turnover.
Second, businesses must ensure that customers retain the right to access, rectify, or erase their data, even if it is hosted abroad. For example, a French tradesperson using a U.S.-based CRM must ensure their provider respects these rights, or risk non-compliance. Finally, in the event of a dispute, European authorities, such as the CNIL, may require data repatriation, complicating operational management.
To avoid these pitfalls, it is recommended to prioritize local or GDPR-certified hosting solutions, such as those offered by Amalya IA. A clear and transparent privacy policy also strengthens customer trust while securing internal processes.
Legal Obligations Under the GDPR for Customer Data Transferred Outside the EU
The General Data Protection Regulation (GDPR) strictly governs the transfer of customer data abroad, particularly outside the European Union. For SMEs and tradespeople, understanding these obligations is essential to avoid penalties that can reach 4% of global turnover. Here are the key rules to apply.
First, any transfer of customer data abroad under the GDPR must be based on a valid legal mechanism. The main options are:
- Adequacy decisions: The European Commission recognizes certain countries (such as Canada or Japan) as providing a level of protection equivalent to the GDPR. Transfers to these destinations do not require additional safeguards. Check the official list here.
- Standard Contractual Clauses (SCCs): For non-recognized countries (United States, India, etc.), pre-approved contracts by the EU must be signed with the data recipient. Example: A tradesperson using a U.S. CRM must require this document from their provider.
- Binding Corporate Rules (BCRs): Reserved for large groups, these allow secure internal transfers after approval by a data protection authority.
Second, a Data Protection Impact Assessment (DPIA) is mandatory if the transfer presents high risks. For example, storing health data or financial information via a foreign cloud requires a detailed evaluation of security measures. Our practical guide offers an adaptable template.
Finally, the principle of minimization applies: only transfer data that is strictly necessary. An e-commerce business shipping packages to the United States does not need to send complete purchase histories of its customers. Prioritize anonymization or encryption before any transfer.
If you have doubts about the compliance of your data flows, consult a GDPR expert or use automated tools like those offered by Amalya IA, specialized in supporting SMEs.
Permitted and Prohibited Countries: Where to Store Customer Data in Compliance
Storing customer data abroad under the GDPR requires heightened vigilance regarding server locations. European regulations distinguish between two categories of countries: those offering an adequate level of protection and others subject to strict restrictions. Here’s how to navigate these constraints to ensure compliance for your SME or craft business.
Permitted countries are those recognized by the European Commission as providing protection equivalent to the GDPR. These include Switzerland, Canada (for commercial data), Japan, and post-Brexit the United Kingdom. These destinations allow free data transfers without additional formalities. For example, a French tradesperson can host customer contact details on a Swiss server without legal risks, provided it is mentioned in their privacy policy.
Conversely, prohibited or conditional countries include the United States, China, or India. For these destinations, the GDPR requires specific safeguards, such as Standard Contractual Clauses (SCCs) or Binding Corporate Rules (BCRs). A concrete example: An SME using a U.S. CRM (like Salesforce) must sign SCCs with its provider and document a Data Protection Impact Assessment (DPIA). Without these measures, the transfer is illegal, exposing the business to penalties of up to 4% of its global turnover.
For unlisted countries, such as certain African or Asian states, a case-by-case evaluation is necessary. The European Data Protection Board (EDPB) provides guidelines to assess the level of protection. When in doubt, opt for hosting within the EU or an adequate country, and consult an expert to secure your customer data abroad under the GDPR flows.

Legal Risks and Penalties for Non-Compliance with the GDPR
Storing customer data abroad under the GDPR exposes businesses to significant legal risks if the rules are not strictly followed. Non-compliance with these obligations can result in financial penalties, reputational damage, and a loss of customer trust. Here are the main risks and penalties involved.
First, administrative fines represent the most direct threat. The GDPR provides for penalties of up to €20 million or 4% of annual global turnover, whichever is higher. For example, in 2021, Amazon was fined a record €746 million for breaches related to personal data processing, including non-compliant international transfers. These sanctions are imposed by data protection authorities, such as the CNIL in France, which often publish their decisions, amplifying the media impact.
In addition to fines, businesses face legal actions from affected individuals. The GDPR grants individuals the right to seek compensation for any material or non-material damage resulting from a data breach. In 2020, the Court of Justice of the European Union (CJEU) invalidated the Privacy Shield, a data transfer mechanism to the United States, due to risks of access by U.S. authorities. This decision forced many companies to revise their contracts and implement Standard Contractual Clauses (SCCs) or Binding Corporate Rules (BCRs) to secure their transfers.
Finally, non-compliance with the GDPR can lead to corrective measures imposed by authorities, such as temporary or permanent bans on data processing or the obligation to delete collected data. These measures can paralyze critical activities, such as customer relationship management or commercial prospecting. To avoid these pitfalls, it is essential to document every transfer of customer data abroad and ensure that recipient countries offer an adequate level of protection, as detailed in our privacy policy.
To secure your practices, consult our experts or regularly audit your compliance processes, especially if you use cloud solutions based outside the EU. A proactive approach limits risks and strengthens customer trust.
Technical Solutions for Storing Customer Data Abroad in Compliance
Storing customer data abroad while complying with the GDPR requires a rigorous technical approach. Several solutions allow you to balance performance and compliance, provided they are implemented methodically.
The first option is to use GDPR-certified hosting providers, such as those offered by European players (OVHcloud, Scaleway) or local subsidiaries of U.S. giants (AWS Europe, Google Cloud Paris). These providers guarantee storage in data centers located within the EU, eliminating risks associated with international transfers. For example, a tradesperson can opt for a dedicated server in France via OVHcloud, with data encryption at rest and in transit, to secure sensitive information.
For businesses working with subcontractors outside the EU, Standard Contractual Clauses (SCCs) or Binding Corporate Rules (BCRs) are essential. These legal mechanisms govern the transfer of customer data abroad to third countries, such as the United States. A concrete example: An SME using a U.S. CRM (like Salesforce) must sign SCCs with its provider and document this compliance in its privacy policy.
Finally, homomorphic encryption or tokenization can minimize risks. These techniques render data unreadable without a decryption key, even if stored abroad. For example, an online store can tokenize credit card numbers via Stripe or Adyen, reducing the impact of an unauthorized transfer.

Case Studies: Companies Penalized for GDPR Non-Compliance
Non-compliance with the GDPR regarding customer data abroad can be costly for businesses, as demonstrated by several recent penalties. These case studies illustrate the legal and financial risks involved, as well as best practices to avoid similar mistakes.
In 2021, the CNIL imposed a €50 million fine on a major fashion retailer for transferring customer data to servers located in the United States without sufficient safeguards. The breach specifically involved the absence of Standard Contractual Clauses (SCCs) and additional protection mechanisms, which are required by the GDPR for transfers outside the EU. The company had to completely revise its privacy policy and implement enhanced data encryption.
Another notable example involves a French software publisher fined in 2022 for storing health data on U.S. servers without a legal basis. The CNIL emphasized that sensitive data, such as health-related information, requires specific protection measures, including for transfers to third countries. The company was fined €1.5 million and had to repatriate its data to Europe or face additional penalties.
These cases demonstrate that transfers of customer data abroad must be governed by robust legal tools, such as Standard Contractual Clauses or Binding Corporate Rules (BCRs). Businesses must also document their Data Protection Impact Assessments (DPIAs) and ensure that subcontractors comply with GDPR requirements. To secure your practices, consult our legal notices and systematically assess risks before any transfer.
Finally, it is crucial to train your teams on GDPR issues and appoint a Data Protection Officer (DPO) if necessary. These preventive measures help avoid costly penalties and strengthen customer trust.
How to Audit and Secure Your International Customer Data Storage
Auditing and securing the storage of customer data abroad in compliance with the GDPR requires a methodical approach. Here are the key steps to assess your practices and reduce legal risks.
Start by mapping your data flows. Identify all foreign providers involved in processing (hosting, CRM, email tools) and verify their GDPR compliance. For example, a tradesperson using a U.S. software like Mailchimp must ensure it offers Standard Contractual Clauses (SCCs) or an updated Privacy Shield. Always consult the privacy policies of providers to confirm their commitment to data protection.
Next, evaluate technical security measures. A European host like OVH or Scaleway guarantees data encryption at rest (AES-256) and in transit (TLS 1.2+), but an Asian provider may require additional audits. Verify the physical location of servers: storing data in Switzerland is conditionally permitted, while the United States requires enhanced safeguards (e.g., EU-US Data Privacy Framework certification).
Document your actions in a processing register, mandatory for SMEs with over 250 employees. For tradespeople, a simplified table suffices: list data categories, recipient countries, and legal bases (consent, contract, legitimate interest). If in doubt, request a personalized audit to validate your compliance.
Finally, train your teams on best practices. A concrete example: an employee exporting a customer database to a U.S. cloud without prior encryption exposes the company to penalties. Implement clear procedures, such as anonymizing data before transfer or using local solutions (e.g., Nextcloud hosted in France).
GDPR Checklist: Key Steps to Store Customer Data Abroad Legally
Storing customer data abroad under the GDPR requires a methodical approach to avoid penalties and ensure compliance. Here is an actionable checklist, step-by-step, with concrete examples to secure your process.
1. Identify the legal basis for the transfer
- Check if the destination country offers an adequate level of protection (official list from the European Commission). Example: Canada (private sector) or Japan are recognized, but the United States is not without specific contractual clauses.
- If the country is not adequate, use appropriate mechanisms: Standard Contractual Clauses (SCCs), Binding Corporate Rules (BCRs), or specific derogations (explicit customer consent, for example).
2. Map the transferred data
- Precisely list the exported data (names, emails, purchase histories, etc.) and its purpose. Example: A tradesperson using a U.S.-based CRM must document that only customer contact details are stored, not sensitive data (ethnic origin, health).
- Limit the volume of data to what is strictly necessary (principle of minimization).
3. Secure contracts with subcontractors
- Require GDPR clauses in your contracts with foreign hosts or providers. Example: Include an annex detailing security measures (encryption, restricted access) and obligations in case of a data breach.
- Verify that the provider complies with ISO 27001 or SOC 2 standards to strengthen trust.
4. Inform customers and obtain consent if necessary
- Update your privacy policy to mention international transfers, their purpose, and the safeguards in place.
- For sensitive data, obtain explicit and documented consent. Example: An online form with a dedicated checkbox.
5. Document and audit regularly
- Maintain a register of transfers (countries, data, legal basis) to prove compliance in case of an inspection.
- Conduct annual audits to verify that technical and organizational measures remain appropriate. Example: Test third-party data access or simulate a breach to assess responsiveness.
