Semarchy: sovereignty score and 8 European alternatives

Semarchy supplies data management software centred on master data management (MDM). The Semarchy Data Platform combines MDM, data governance with policies, workflows and audit trails, data quality, data integration and DataOps, and focuses on building data products for teams, AI agents and applications. SemQL provides a SQL-like language for data and context. According to the vendor, the platform is available as SaaS, on-premises, in the cloud and on Snowflake, at the customer's choice.

Semarchy lists offices in Phoenix (Arizona, United States), Lyon (France), Poole (United Kingdom) and Gurgaon (India). The company operates globally from the US, which is relevant for the CLOUD Act. Its website displays ISO 27001 and SOC 2 badges. The sources consulted do not say where the SaaS option hosts data. With an on-premises or self-managed cloud deployment, you decide the location yourself. The software is not open source.

Why digital sovereignty matters with Semarchy

Semarchy 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.

Semarchy 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.

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