GDPR Considerations

Communication platforms process some of the most personal data in your application stack: customer phone numbers, SMS message content, voice call recordings, and two-factor authentication codes. Every time your application sends a verification SMS, a delivery notification, or makes an automated phone call, your CPaaS provider processes the recipient's personal data. With US-based providers like Twilio, this data is processed under US jurisdiction. European CPaaS providers route communications through EU infrastructure, ensuring that your customers' phone numbers, message content, and call metadata stay within European jurisdiction. This is especially critical for two-factor authentication flows, where the provider processes both the user's phone number and a security-sensitive verification code. For businesses operating in regulated industries like healthcare or finance, choosing an EU-based communication platform is essential for maintaining end-to-end GDPR compliance in customer-facing communication flows.

Communication Platform — Frequently Asked Questions

Why is Twilio a GDPR risk for sending SMS to EU customers?
Twilio is a US company that processes phone numbers, message content, delivery metadata, and call recordings on US infrastructure. Every SMS your application sends through Twilio transfers the recipient's phone number and message content to Twilio's US servers. For two-factor authentication, this means security codes pass through US-controlled infrastructure. Twilio is subject to the CLOUD Act, meaning US authorities can compel access to this communication data. European CPaaS providers process all communications data within the EU, eliminating the cross-border data transfer and keeping customer phone numbers and message content under GDPR protection.
Does switching CPaaS provider require rebuilding our communication features?
Most CPaaS providers offer similar REST API patterns for sending SMS, making voice calls, and managing phone numbers. The migration typically involves updating API endpoints, authentication credentials, and adjusting to slightly different request and response formats. European CPaaS providers like MessageBird (now Bird), Sinch, and CM.com offer client libraries for popular programming languages and comprehensive API documentation. For basic SMS and voice functionality, a migration can be completed in a few days. More complex features like IVR flows or WhatsApp Business integration may require additional adjustment.
How do European CPaaS providers handle call recordings and message logs under GDPR?
European CPaaS providers store call recordings and message logs on EU infrastructure with configurable retention periods. Under GDPR, you must inform customers when calls are recorded and have a lawful basis for storing the recording. European providers typically offer automatic deletion of recordings after a defined period, encrypted storage at rest, and the ability to delete individual recordings on request for data subject rights compliance. Message logs containing phone numbers and delivery metadata are also personal data, and EU providers offer log retention controls to help you meet GDPR's data minimization requirements.
