Our Recommended Approach to Designing
for “End-to-End Encryption” into Kafka Clients

When an enterprise subscribes to Confluent Cloud™ services, their data is encrypted in motion and at rest. This document outlines our recommended approach to designing for “end-to-end encryption” into Kafka clients, in other words, for encryption both in motion and at rest. It is based on a symmetric encryption scheme. It is intended for engineering design teams who seek to implement end-to-end message payload encryption on the Confluent Cloud platform.
