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

CGU operates as an essential government entity within Brazil's public sector, delivering transparency and integrity services. Its business model is non-commercial, focusing on public service delivery and governance. The website integrates with partner government platforms such as Portal da Transparência and uses official government IT infrastructure (SERPRO). The agency maintains active social media channels to engage with the public and disseminate information. The site reflects a mature digital presence with a focus on accessibility and citizen engagement.

Security posture

The website demonstrates a strong security posture with enforced HTTPS, modern security headers, and no visible vulnerabilities or exposed sensitive data. However, it lacks explicit published security policies, incident response contacts, and a vulnerability disclosure program, which are recommended best practices for government sites. The use of trusted hosting by SERPRO and consistent domain registration data further enhance trust. The site uses Google Tag Manager for analytics but maintains good privacy compliance with cookie consent mechanisms.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and frameworks.
  2. Establish and publicize incident response contact channels such as security@ or abuse@ emails.
  3. Implement a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting.
  4. Enhance direct contact information availability, including official phone numbers and emails for public inquiries.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the Plone CMS platform, leveraging technologies such as jQuery, Swiper.js, and Font Awesome for UI components. It integrates Google Tag Manager for analytics and uses SERPRO as the hosting provider, indicating a robust and government-grade infrastructure. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data. Performance is moderate, with room for optimization. The technical implementation aligns well with modern web standards and government digital service requirements.
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.
