Signals, not verdicts. A domain appears here because heuristics matched its name, its infrastructure or the page it served on its first day. Where a model has looked at it, that is shown as an opinion with a confidence, not as a finding. Nothing on this page says a site is malicious. Read the evidence and decide for yourself.

Model opinions

Second opinionlooks benignconfidence 88%· claude-opus-5-5

cestco.org hosts a coherent Spanish/English corporate site for CESTCO S.A.S., a Colombian defense-engineering firm founded in 2017. It has its own logo, is served from Colombian hosting, and its only form is a contact form (name, organization, email, country), with no password field. Nothing on the page references Costco, so the scorer's cestco≈costco match looks coincidental.

First passlooks benignconfidence 92%· claude-haiku-4-5

CESTCO is a legitimate Colombian defense/engineering company founded in 2017 with a genuine corporate website describing its services, history, and capabilities. While the domain name acoustically resembles 'Costco', the page content, Spanish language, corporate structure, and specific technical/defense focus demonstrate this is the company's authentic site, not an impersonation attempt. The form is a standard business contact form, not a credential-harvesting page.
