Verifying against the live site and live WHOIS/DNS…
Common questions
Is drei.at legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns drei.at?
Nobody has completed AboutUs's owner verification for drei.at. That's true of most sites here — it isn't itself a warning sign.
Correct a description, link or other detail. Submissions are reviewed before publication.

AboutUs has not vetted this site. Everything below is what we could measure automatically. Anything you do on the site — paying, sharing personal details, downloading — is between you and the site, not AboutUs.
Current facts
Latest available measurements; dated entries retain their dates. These are measurements, not an endorsement of the site.
not yet retrieved
Registrar and registration date not retrieved yet — we retry on every view.
We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 5 days ago); 3/3 transport and email checks available (oldest recorded about 5 days ago). This is evidence coverage, not a probability that a website is safe.
No caution flags in the available scoring observations; this is not a complete safety assessment
