GOV.BR is the official Brazilian government portal consolidating digital services and information across all government sectors. It serves a broad audience including citizens, businesses, public servants, and other social segments by providing access to tax services, digital signatures, personal data consultation, and more. The portal is positioned as a central hub for government digital transformation and citizen engagement. Technically, the site leverages modern web technologies such as Plone CMS, jQuery, Swiper.js, and Font Awesome, hosted on SERPRO infrastructure, ensuring a robust and accessible platform. Security measures include HTTPS enforcement, comprehensive security headers, and cookie consent mechanisms, reflecting a mature security posture.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The portal operates as a government essential entity providing digital public services and information dissemination. Its market position is unique as the official digital gateway for Brazilian federal government services, with no direct commercial competitors. The business model focuses on service delivery and citizen engagement rather than revenue generation. Key services include tax consultation, digital identity management, and access to government programs. The portal integrates with multiple government agencies and leverages partnerships with SERPRO and other government bodies. Growth indicators include continuous addition of digital services and mobile app offerings. The ecosystem includes social media channels and official communication platforms, enhancing outreach and transparency.

Security posture

The GOV.BR portal exhibits a strong security posture with HTTPS enforced and multiple security headers implemented, reducing risks of common web attacks. The absence of exposed sensitive data and secure form practices further strengthen security. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure program limits transparency and may delay incident handling. No known vulnerabilities or suspicious patterns were detected in the content or WHOIS data. The portal would benefit from publishing a security.txt file and providing direct security contact channels to improve incident response readiness and stakeholder trust.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and user guidance.
  2. Implement and publicly disclose a vulnerability disclosure policy and security.txt file.
  3. Provide explicit contact information for security incidents, including emails or phone numbers.
  4. Regularly review and update third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance transparency on data protection officer contact and data retention policies.

Technical notes

Notes

The GOV.BR portal is built on the Plone CMS platform, utilizing modern JavaScript libraries such as jQuery and Swiper.js for interactive components. It employs Font Awesome for iconography and integrates Google Tag Manager for analytics and marketing. Hosting is managed by SERPRO, a Brazilian government IT service provider, ensuring alignment with government infrastructure standards. Performance is moderate with good mobile optimization and accessibility features implemented. SEO is well addressed through meta tags, Open Graph, and structured data (JSON-LD). The site uses secure HTTPS connections and enforces security headers, reflecting a mature technical implementation. Opportunities exist to improve performance monitoring and implement advanced security automation.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
