Tellius: sovereignty score and 8 European alternatives

Tellius is an AI-assisted analytics platform for business data. It combines data integration and a semantic layer, insights such as root-cause analysis and anomaly detection, visualisations, and conversational AI agents that answer questions about data and prepare briefings. According to its documentation, Tellius runs on Kubernetes and is available either as a customer-hosted environment, in the customer's own cloud or on-premises, or as a Tellius-hosted environment, usually on AWS EKS or Azure AKS.

Tellius, Inc. is a US company based in Reston, Virginia. The privacy policy states that information may be stored and processed in the United States or another country, and includes a GDPR section describing data-subject rights. A data processing agreement or sub-processor list is not publicly named. A European organisation that hosts the platform itself limits its exposure to US jurisdiction, but the vendor remains American.

Why digital sovereignty matters with Tellius

Tellius 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.

Tellius hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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