Is this website trustworthy? Domain age, HTTPS, company and sanctions (site confiável)

Liveby Site trust check

Checks a website before you pay it or sign up, in one call.

Give a site and optionally the CNPJ it shows; you get how old the domain is and who registered it (for .br sites, the owner's CNPJ from registro.br), whether its HTTPS certificate is valid, the company behind the CNPJ (Receita status, opening date, legal name), whether that company is barred in the federal CEIS/CNEP registers, and a list of plain signals marked red, amber or green: a domain created weeks ago, a CNPJ that is closed or opened days ago, a CNPJ on the page that is not the domain owner, a person instead of a company owning a shop's domain. It does not give a single verdict: weigh the signals. Free.
