Similarweb: sovereignty score and 8 European alternatives

Similarweb provides web traffic and market intelligence data, with products covering web, app, retail and sales intelligence. The data is delivered as a data-as-a-service offering, through an API, data feeds and a browser extension. The company describes its mission as providing digital data for market analysis. The product is a hosted service, and no self-hosted version is described in public sources.

Similarweb Ltd. is an Israeli company with its main office in Givatayim, Israel, and it is listed on the New York Stock Exchange. Its privacy policy states that personal data is held on servers in the United States, where its central database is operated, and that transfers rely on EU standard contractual clauses. The policy does not name European data centres. For a European organisation, an Israeli headquarters combined with US storage means that transfer arrangements and the origin of the data used deserve close review. The product is not open source.

Why digital sovereignty matters with Similarweb

Similarweb is headquartered in IL, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Similarweb 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.

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