sgb.gov.br is the digital home of the Serviço Geológico do Brasil (Brazilian Geological Survey), a federal agency under the Ministry of Mines and Energy. For a government site, transparency is crucial — and this one delivers. The domain is registered to the Companhia Pesquisa de Recursos Minerais, with clear contact details and an active social media presence. Security is on point: valid TLS encryption, forced HTTPS, and no blacklist history. That said, the site does lack DNSSEC (a protective layer for DNS queries), which is unusual for a .gov.br domain. If you're looking for geological data, mining regulations, or official publications, this is the real thing. The hidden elements warning (likely menu items and accessibility features) isn't a red flag for a government portal. Overall, sgb.gov.br passes the safety check. There are no signs it's a scam or fake — just a slightly overdue technical upgrade holding it back from a perfect score.
In plain English
sgb.gov.br is the official website of Brazil's Geological Survey (SGB), a government agency. It has strong security, transparent ownership, and all the expected legal pages. A few technical gaps like missing DNSSEC don't outweigh the clear signs this is a legitimate public service. You can trust it for official information and services.
Where the score comes from
The site uses modern encryption with a valid certificate from Brazil's academic network, forces HTTPS, and blocks clickjacking. No malware or phishing flags detected. That's a solid security posture for a government website.
WHOIS records clearly show the owner is Companhia Pesquisa de Recursos Minerais (CPRM), a federal government entity. The domain is a few years old, but the responsible persons and contact emails are on record. This is as transparent as you'd expect from a public agency.
No blacklists, no Google threats, and a modest but legitimate web presence. The Wayback Machine was temporarily unavailable, but nothing here suggests abuse or a sketchy history. A clean bill of health.
The site has a detailed About page, contact information, links to six social media platforms, and clear branding. For a government service, this is above average in openness about who runs it and how to reach them.
Privacy policy and terms of service are both published, which is appropriate for a government portal that may handle user data. Brazil's privacy law (LGPD) would expect these. No cookie consent notice was spotted, but the site's main purpose appears informational.
The site uses Google's mail servers with SPF and DMARC authentication, and has a proper sitemap. However, DNSSEC is not enabled, which is a notable gap for a .gov.br domain. The hosting on Brazil's national research network is fitting, but the missing DNS security layer is a minor concern.
