Confluent: sovereignty score and 8 European alternatives

Confluent is a data streaming platform built on Apache Kafka by its original co-creators. It offers Kafka as a managed service (Confluent Cloud), connectors, Stream Governance with Schema Registry, and stream processing based on Apache Flink. You can also operate it yourself with Confluent Platform on your own servers, or choose Confluent Private Cloud. Confluent Cloud runs on AWS, Azure and Google Cloud, with European regions including Frankfurt, Ireland and Paris.

Confluent, Inc. has its headquarters in the US and was acquired by IBM on 17 March 2026, which bought all outstanding shares. The company therefore falls under US jurisdiction, including the CLOUD Act, even when data sits in a European region. The commercial products are proprietary and not open source, although Apache Kafka itself is open source. Organisations choosing Confluent Platform or Private Cloud keep data processing under their own control but remain dependent on a US vendor for licences and support.

Why digital sovereignty matters with Confluent

Confluent is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Confluent hosts data in EU, US. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Confluent is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Confluent together with your other vendors and gives a total score, a heatmap and the main risk drivers.
