A .si address is not a safety guarantee. It identifies a domain registered under Slovenia’s country-code top-level domain, but it does not confirm that a site is genuine, harmless, or run by the organization it claims to represent. Check the complete address and how you got the link before sharing passwords, payment details, or one-time codes.
What does .si tell you?
The .si domain is Slovenia’s country-code top-level domain, managed by Register.si within ARNES. The ending identifies the domain namespace—not the site operator’s identity or trustworthiness. A legitimate-looking .si address can host misleading or harmful content, just as a site using another suffix can.

A domain registration and the material published at that domain are separate things. Register.si says it does not monitor or determine the legality of site content, and that it cannot remove problematic content itself; removal is a matter for the content or hosting provider. Its page states: “Monitoring and assessing the legality of online content is not the responsibility of the Registry .si and is not one of its tasks.” Register.si’s domain-abuse explanation describes the limits of its role.

How to check whether a .si link may be a scam
- Read the whole hostname, from right to left. Identify the actual domain, rather than relying on a brand name in a longer address or in the page path. For example, a familiar name appearing before an unrelated domain does not make that address official.
- Compare it with an independently verified address. Look for misspellings, extra words, deceptive subdomains, or unexpected redirects. Find the organization’s address through a source you trust, such as its official app or a previously saved bookmark, rather than following the suspicious message’s link.
- Consider the message that delivered the link. Unexpected urgency, account-suspension threats, prize claims, payment demands, and requests for passwords or one-time codes are reasons to stop and verify through a separately obtained contact route.
- Do not treat security indicators as a verdict. HTTPS or a padlock indicates an encrypted connection to that hostname; it does not establish that the site operator is honest. A .si suffix, a registration record, or DNSSEC is not a site-safety certificate either.
- When in doubt, do not submit sensitive information. Use an up-to-date browser and its security protections. If a link appears to be phishing, consult SI-CERT’s current reporting instructions.
What WHOIS and RDAP can—and cannot—tell you
Register.si’s WHOIS guidance says a lookup can provide basic details about a domain, its holder, technical contact, and registrar. For a natural-person holder, the page says only the contact email is disclosed as holder information; further disclosure requires a justified request.
#1 Best Overall
The registry also offers RDAP, a structured domain-lookup service. Anonymous users do not see holder or technical-contact data, and authenticated access depends on authorization. Limited or private registration details are not proof of wrongdoing—but neither a visible record nor a real registration proves that a particular page is legitimate. A registered domain may still host malicious, compromised, misleading, or abandoned content.
What DNSSEC establishes
DNSSEC is intended to support authentication of DNS sources and integrity protection for DNS data in transit. When DNSSEC validation is correctly configured, it can reduce certain DNS-tampering risks. It does not inspect a website’s content, verify a seller’s identity, or validate business claims. The .si DNSSEC practice statement also notes that relying parties are responsible for configuring and updating trust anchors.
How to report a suspected phishing link in Slovenia
As of SI-CERT’s page dated 30 September 2026, its national phishing reporting point began operating on 1 October 2026. The page invites users to send phishing emails, links to phishing sites, or screenshots of SMS and messaging-app messages to [email protected]. SI-CERT says it analyzes reports, extracts URLs, confirms phishing pages, shares confirmed entries through automated processes with browser warning lists, and tries to have fake pages disabled by their hosting providers. Check SI-CERT’s current official page for the latest reporting instructions, since contact routes and operational details can change.

How to compare two suspicious links
If you are choosing between links that claim to lead to the same organization, compare the signals that bear directly on the destination and the request:
- Hostname: Does the actual domain match an address independently confirmed as official?
- Delivery and pressure: Did the link arrive unexpectedly, use threats or urgency, or ask for unusual information?
- Consistency: Does the page’s claimed organization and purpose make sense for the address and the way you reached it?
- Independent warnings: Do an up-to-date browser or reputable security tools flag the URL?
WHOIS/RDAP and DNSSEC can add context about registration and DNS, respectively, but neither decides whether a site’s content or operator is trustworthy.
