Data Security and Compliance

Yes! We offer a European-based data region to store your Customer.io data. New customers will be presented the option to select US or EU regions when creating their accounts.

Absolutely, we provide the latest version of the Customer.io DPA for you to read or download on our legal page. You can find additional information regarding GDPR & Customer.io here, as well as more information about our security practices here.

Our Site Reliability team rapidly investigates all reported security issues. If you believe you’ve discovered a bug in Customer.io’s security, please get in touch by email at ctf@customer.io. We will respond as quickly as possible to your report. We request that you not publicly disclose the issue until it has been addressed by Customer.io’s Site Reliability team.

Learn more by reading our report a vulnerability page. 

When you purchase a paid Customer.io subscription, your credit card data is not transmitted through nor stored on our systems. Instead, we depend on Stripe, a company dedicated to this task. Stripe is certified to PCI Service Provider Level 1, the most stringent level of certification available. Stripe’s security information is available online.

Customer.io does not currently maintain active ISO 27001 compliance. Our compliance program and control environment is influenced by ISO 27001 principles and we have an ISMS policy and committee within the company. We will explore formal ISO 27001 compliance at a future date.

We communicate service impacting outages to our customers via our status page at https://status.customerio.com.

Data transmitted to Customer.io, via our API, is encrypted in transit through the use of the HTTPS protocol.

Our system data is encrypted at rest using Cloud KMS services.
