Frosmo: sovereignty score and 8 European alternatives

Frosmo is a personalisation platform for digital services. It offers an AI-driven personalisation engine with A/B testing and automated optimisation, managed through a control panel. It integrates with e-commerce platforms and headless content management systems, and it is delivered as a hosted service with a JavaScript library that runs on the customer's website.

Frosmo Technologies Oy is a Finnish company headquartered in Helsinki, founded in 2008. Its website does not name a parent company or owner. The privacy policy states that platform data is stored in SQL databases hosted by trusted partners, without naming them or their locations, and that personal data is not transferred outside the EU or EEA. Analytics and other third-party services may, however, process data on servers in the United States. For a European organisation, a Finnish provider with no stated foreign parent is relevant; the unnamed hosting partners and US analytics processors should be reviewed with the vendor.

Why digital sovereignty matters with Frosmo

Frosmo is headquartered in FI and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Frosmo scores best on data residency.

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