staysin.eu - does your data stay in the EU?Recently scanned domains

How it works<br>What does staysin.eu check?staysin.eu analyses seven layers of a domain's infrastructure: hosting provider, DNS nameservers, CDN, mail servers (MX), server location, TLS certificate issuer, domain registrar, and third-party requests loaded by the website. Country is determined by matching the operator's ASN to known providers - reflecting legal jurisdiction, not just where a particular server sits. For details, see the full methodology.<br>How is EU sovereignty determined?A domain "stays in EU" when all scored services are operated by EU-based providers or resolve to EU IP addresses. If at least one scored service is outside the EU, the domain "leaves EU". Country is determined by provider jurisdiction (ASN match) when possible, with IP geolocation as fallback. Server location always uses IP geolocation to show where data physically travels.<br>How is the score calculated?The score ranges from 0 to 100. Each scored service (hosting, DNS, CDN, mail, server location, and third-party requests) contributes equally. Services in the EU add to the score; services outside the EU reduce it. Informational items like the TLS certificate authority and registrar are displayed but excluded from scoring.<br>Why does digital sovereignty matter?When data leaves the EU, it may be subject to foreign surveillance laws like the US CLOUD Act or FISA Section 702. EU regulations like GDPR require adequate data protection. Using EU-based infrastructure ensures data remains under EU jurisdiction and reduces legal risk for businesses and public institutions.<br>Is staysin.eu free?Yes. staysin.eu is completely free and built by enum, a European infrastructure company.
