What are the best practices for cross-border data transfers under GDPR?

Use adequacy decisions, Standard Contractual Clauses, or binding corporate rules, while conducting transfer impact assessments for third countries.

Cross-border data transfers under GDPR require careful legal and technical planning to ensure personal data receives adequate protection when transferred outside the EU. Organizations must implement appropriate safeguards and continuously monitor transfer arrangements.

Transfer Mechanisms: Prioritize transfers to countries with adequacy decisions (UK, Japan, Canada, etc.). For other destinations, use Standard Contractual Clauses (SCCs) - the most common mechanism for commercial transfers. Large multinationals may implement Binding Corporate Rules (BCRs) for intra-group transfers.

Transfer Impact Assessments: Conduct thorough assessments of destination country laws, particularly government surveillance capabilities and data localization requirements. Document how you'll address any risks through supplementary measures.

Supplementary Measures: Implement additional technical safeguards like encryption in transit and at rest, pseudonymization, or data minimization. Consider organizational measures such as data governance agreements and regular audits of transfer arrangements.

Documentation Requirements: Maintain detailed records of all international transfers, including legal basis, recipient details, categories of data, and safeguards implemented. Update transfer documentation when circumstances change.

Ongoing Monitoring: Regularly review transfer arrangements, especially when destination country laws change. Be prepared to suspend transfers if adequate protection cannot be maintained.

Cloud Services: Special attention needed for cloud providers with global infrastructure. Ensure contracts include appropriate transfer safeguards and data location controls.

Kenny Hietbrink from Hack-IT recommends implementing technical measures that protect data regardless of location, creating defense in depth for international operations.
