Registered 2003 · site is live · HTTPS valid
wisconsindot.gov has an AboutUs profile for public website intelligence, ownership context, trust signals, monitoring, and owner verification.
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 53 days ago); 3/3 transport and email checks available (oldest recorded about 53 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
Site history
