Stardog: sovereignty score and 8 European alternatives

Stardog is an enterprise knowledge graph platform for connecting and querying data from many sources, with a semantic layer intended to give AI applications context. It is offered as Stardog Cloud, as Cloud Prem inside the customer's own virtual private cloud, and as on-premise software for Kubernetes and Linux environments. Enterprises use it for data integration, governance and semantic AI. The vendor states that it aims to avoid lock-in to a proprietary environment.

Stardog Union is headquartered in Arlington, Virginia, United States, according to its privacy policy and website footer. Stardog Cloud is listed with AWS regions in the United States and in Frankfurt (eu-central-1). The vendor does not publish a data residency commitment, and its privacy policy names no hosting locations. Transfers rely on standard contractual clauses. The Cloud Prem and on-premise options let an organisation run Stardog in its own environment and keep control of the data. As a US company, Stardog is subject to US law, so a European buyer should contract for EU data location or evaluate the self-managed options.

Why digital sovereignty matters with Stardog

Stardog 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.

Stardog 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.

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