When you operate as a commercial partner under the EU’s General Data Protection Regulation (GDPR), the rules are not optional. Every API call, database entry, and log file holding personal data falls under the regulation’s reach. A GDPR commercial partner is any entity that processes, stores, or transmits personal data for another company. That means you are accountable for the rights of data subjects, for breach notifications, and for ensuring privacy by design across all systems you touch.
The obligations are clear. You must have a lawful basis for processing. You must document data flows with precision. Data minimization is not a suggestion — it is a requirement. Every third-party service you use must also comply, or your own compliance fails. As a commercial partner, contracts with controllers and other processors must include GDPR-specific clauses: purpose limitation, subprocessor controls, deletion timelines.
Security is not just encryption. It is controlling access, auditing changes, and proving those controls work. GDPR demands you detect unauthorized access fast and notify controllers within 72 hours. Logs should be immutable. Backups must respect retention schedules and deletion requests.
