TLS 1.3 has been introduced as an opt-in feature on Confluent Cloud Dedicated clusters, enhancing encryption for data in transit and aligning with stringent security and compliance standards. This upgrade allows organizations to strengthen their security posture with improved cryptographic algorithms and maintain control over their security configurations. While TLS 1.3 will become the default on April 30, 2026, for all new and existing clusters across various types—such as Enterprise, Freight, Standard, and Basic—Confluent will continue supporting TLS 1.2. This ensures that existing connections will remain functional when the transition occurs. Users of Dedicated clusters can enable TLS 1.3 immediately by following specific configuration steps, whereas users of other cluster types will experience automatic activation without manual intervention.
