Is .si safe? The state of .si domain security — Slovenia

.si is safer than the internet average. Across 128,121 graded .si domains, 46% score an F — cleaner than the 73.8% global average — better company than most of the web. 2.1% earn a B or better. Most .si domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.

Note: .si is used as a proxy for Slovenia based on the domain's TLD, not where the company is registered.

Does .si make a domain secure?

No — and that's the most important thing to know. A domain's grade is decided by how it is configured (SPF, DMARC, HTTPS, DNS), not by its ending. Choosing .si doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .si domain earns an A while the crowd around it sits at F.

Frequently asked questions

Is .si safe?

On average, .si is safer than the internet average: 46% of its 128,121 graded domains score an F as of 2026-07-29, against a 73.8% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.

How secure are .si domains?

54.0% of .si domains score above an F and 2.1% earn a B or better. The rest fail the basic externally observable protections, most importantly enforced SPF and DMARC, so they can be impersonated in email.

Does choosing .si make my domain secure?

No. A domain's grade comes from how it is configured — SPF, DMARC, HTTPS, DNS — not from its ending. A well-configured domain earns an A on any ending; an unconfigured one sits at F on .si too.

What does "grade F" mean for a .si domain?

It fails the basic protections we can observe from outside — above all, it has no enforced SPF and DMARC, so its email can be forged and its customers targeted with convincing fakes.
