How is data exported for BigQuery secured on S3?

Amazon S3 has a range of compliance and privacy certifications, and uses cutting-edge encryption to protect data at-rest and in-transit to ensure strict data security.

Matomo lets you generate access credentials three times within a 24-hour period. The access key allows you to invoke the export from Matomo and setup the BigQuery data transfer from S3 through an authorised connection. It is important to keep these credentials secure and confidential.
