Subprocessors List

Updated June 4th, 2026

What is a subprocessor?

In order to provide its services, Svix may engage third parties to carry out data-processing activities that involve access to customer data. These organizations, called “subprocessors,” are identified below with their locations and the types of services they provide to Svix.

Svix distinguishes between two categories of data:

  • Customer Content: the data Svix customers send through the Svix service on behalf of their own users, such as message payloads and related metadata. For this data, Svix itself acts as a processor (or subprocessor) on behalf of its customers.
  • Account Data: information about Svix customers themselves, such as account, billing, usage, and support data. For this data, Svix acts as the data controller; and it doesn't include Customer Content or other data about the customers or users of Svix customers.

Subprocessors of Customer Content

The only subprocessor with access to Customer Content is Amazon Web Services (AWS). Customer Content is stored and processed exclusively in the AWS region selected by the customer, and does not leave that region. No other vendor listed on this page has access to Customer Content.
