IONOS Domains: sovereignty score and 8 European alternatives

IONOS Domains is the domain registration service of IONOS, a provider of cloud, hosting, email and website products. More than five hundred extensions are available, including .de, .com, .eu and .io. Domains can be transferred in and renew automatically unless you switch that off. Included features are a domain lock against unwanted transfers and an SSL certificate, with management of DNS records such as A, CNAME, MX and TXT. Domains can be linked to email, Microsoft Exchange, Google Workspace, hosting and website builders. The service is delivered as SaaS.

IONOS SE is headquartered in Montabaur, Germany, and is part of the United Internet Group. The services are not open source. IONOS operates data centres in several countries, including Germany, the United Kingdom and the United States, so the chosen location determines where data resides. For a European organisation this is a German provider under EU law.

Why digital sovereignty matters with IONOS Domains

IONOS Domains 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 IONOS Domains scores best on data residency.

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