Google Cloud Dataplex: sovereignty score and 8 European alternatives

Knowledge Catalog, formerly Dataplex Universal Catalog (Dataplex), is a Google Cloud service that brings together technical metadata and business context across structured and unstructured data. It discovers and indexes metadata from sources such as BigQuery, AlloyDB and Spanner without moving the underlying data. It offers glossaries and review workflows for governance, rule-based data quality checks and scans, profiling, column-level lineage and natural-language search, and MCP servers and a context API let AI agents use the same metadata. The service is delivered through Google Cloud; Google states the rename took effect on 10 April 2026, with API, client library, CLI and IAM names unchanged.

The service is operated by Google, a US company, and European organisations typically weigh US legislation such as the CLOUD Act when using US-headquartered providers. Google lists European locations for Knowledge Catalog, including the eu multi-region and regions such as Belgium, Finland, Frankfurt, the Netherlands, Paris and Warsaw, so data location can be set in Europe. It is a closed Google Cloud service, not open-source software.

Why digital sovereignty matters with Google Cloud Dataplex

Google Cloud Dataplex 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.

Google Cloud Dataplex hosts data in US, EU. 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.

Google Cloud Dataplex 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 Google Cloud Dataplex together with your other vendors and gives a total score, a heatmap and the main risk drivers.
