Verifying against the live site and live WHOIS/DNS…
Common questions
Is csus.edu 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 csus.edu?
Nobody has completed AboutUs's owner verification for csus.edu. That's true of most sites here — it isn't itself a warning sign.

HTTPS request succeeded for www.csus.edu.
checked Sep 29, 2026
The site names California State University, Sacramento as the organisation behind it.
checked Sep 29, 2026
The live front page reads as an education or reference site that is a public service, mainly for students and teachers.
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 71 days ago); 3/3 transport and email checks available (oldest recorded about 71 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
