0–100, higher is better. How it is calculated

The website www.gov.br is the official Brazilian federal government portal designed to centralize access to public services and government information. It serves a broad audience including citizens, businesses, public entities, and other social segments. The portal offers a comprehensive range of digital services, information dissemination, and citizen engagement tools, positioning itself as a critical digital infrastructure for government-citizen interaction in Brazil. The site is well-branded, professionally designed, and consistently maintained, reflecting its authoritative status. Technically, the site leverages the Plone CMS platform, integrates modern JavaScript libraries such as jQuery and Swiper.js, and employs Google Tag Manager for analytics and tracking. Hosting is managed by SERPRO, a trusted Brazilian government IT service provider. The site demonstrates good mobile optimization, accessibility, and SEO practices, ensuring broad usability and reach. From a security perspective, the portal enforces HTTPS, includes cookie consent mechanisms, and avoids exposing sensitive data. However, explicit security headers like X-Frame-Options and X-Content-Type-Options are not clearly detected and could be improved. No dedicated security policy or incident response contacts are published, and no vulnerability disclosure program or security.txt file is found, indicating areas for enhancement in transparency and security maturity. Overall, the portal is highly trustworthy and professionally managed, with strong alignment between domain registration data and official government infrastructure. It poses minimal risk and serves as a reliable digital gateway for Brazilian government services.

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 gov.br portal occupies a strategic position as Brazil's centralized government digital services platform, consolidating access to over 5,350 services with a high percentage of digital offerings. Its business model is government-funded, focusing on service delivery and information transparency rather than commercial revenue. The portal targets diverse user segments including citizens, businesses, public servants, and NGOs, facilitating broad government engagement. Partnerships with official government agencies and integration with federal IT infrastructure (SERPRO) strengthen its ecosystem. The portal's extensive service catalog, user profiles, and app gallery indicate a mature digital government initiative with ongoing expansion plans. Its market position is unique and essential within Brazil's public sector digital transformation efforts.

Security posture

The security posture of gov.br is solid with mandatory HTTPS enforcement and cookie consent compliance. The site avoids exposing sensitive information and uses reputable third-party libraries without known vulnerabilities. However, the absence of explicit security headers and lack of published security policies or incident response contacts represent gaps in security transparency and defense-in-depth. No vulnerability disclosure or security.txt presence limits external security researcher engagement. Overall, the portal demonstrates good baseline security practices appropriate for a government site but would benefit from enhanced security header implementation and formalized security communication channels to improve resilience and trust.

Recommendations

  1. Implement and explicitly publish security headers such as X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy to strengthen browser security.
  2. Publish a dedicated security policy page including incident response contacts to improve transparency and readiness.
  3. Establish and publicize a vulnerability disclosure program and security.txt file to engage the security research community.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility and mobile optimization continuously to maintain high user experience standards.

Technical notes

Notes

The website is built on the Plone CMS platform, a robust and secure content management system favored by government entities. It uses modern JavaScript libraries including jQuery and Swiper.js for UI components and interactivity. Google Tag Manager is integrated asynchronously for analytics and marketing purposes. The site loads multiple CSS and JS resources from gov.br domains and trusted CDNs, indicating a well-managed asset pipeline. Hosting is provided by SERPRO, a Brazilian government IT service provider, ensuring compliance with government hosting standards. Performance is moderate with room for optimization, but mobile responsiveness and accessibility features are well implemented. The technical stack reflects a mature, government-grade digital platform with good maintainability and security posture.
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.
