Site Search 360: sovereignty score and 8 European alternatives

Site Search 360 is a hosted search service for websites, with a separate product for online shops. Organisations use it to run the search function on their site without operating search infrastructure themselves. The provider offers it as an online service. The vendor's public pages do not mention an open-source edition or a self-hosted version.

The service is made by the search specialists behind Zoovu (Germany) GmbH, formerly SEMKNOX, which is based in Dresden, Germany. The website does not state who owns the company. According to the privacy page, server hosting is provided by Hetzner GmbH; the page does not name the countries of the data centres. The provider refers to a pre-signed Data Processing Addendum (DPA). Stripe for payments and HubSpot for website chat are also named as service providers, without stating where they process data. A European organisation should review the DPA and ask for the list of sub-processors before use.

Why digital sovereignty matters with Site Search 360

Site Search 360 is headquartered in DE 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 Site Search 360 scores best on data residency.

Site Search 360 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 Site Search 360 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
