Lighthouse: sovereignty score and 8 European alternatives

Lighthouse is an eDiscovery and legal technology company. It provides managed eDiscovery services, a self-service platform called Spectra, document review, digital forensics and collection, information governance, litigation and trial preparation, and AI analytics under the LighthouseIQ name. It also offers Relativity aiR. The offering combines software with legal services and is delivered mainly as a hosted service.

The contracting entity is Lighthouse Document Technologies Inc. in the United States, so US jurisdiction, including the CLOUD Act, applies. According to its privacy policy, data centres are located in Seattle and Phoenix in the US, London in the UK, and Frankfurt and Dornach in Germany, and Relativity instances are hosted in the region the customer specifies. For customer services, Lighthouse acts as processor on written client instructions, relies on the EU-US Data Privacy Framework and Standard Contractual Clauses for transfers, and has an EU representative in Berlin. A European legal department can therefore request EU-region hosting, but should confirm which data centre and which sub-processors are used for a given matter.

Why digital sovereignty matters with Lighthouse

Lighthouse 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.

Lighthouse hosts data in US, EU, OTHER. 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.

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