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

The website represents an official Brazilian government digital service focused on accessibility for deaf users through the VLibras suite, which provides automatic translation of digital content into Brazilian Sign Language. It is a collaborative initiative involving multiple government ministries and a federal university, positioning it as a key accessibility tool within the government digital ecosystem. The site is hosted on a government domain with appropriate technical infrastructure and uses modern web technologies including Plone CMS, jQuery, and Google Tag Manager. The design and content quality are good, with clear navigation and accessibility considerations. Security posture is solid with HTTPS enforced, but lacks explicit security headers and published privacy or cookie policies. No contact information or incident response details are provided on the analyzed page, which limits transparency in these areas. Overall, the site is trustworthy and professionally maintained, serving a critical public service function.

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.

Priority findings

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Cloudflare, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain:

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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 VLibras project is positioned as a government essential service targeting accessibility for the deaf community in Brazil. Its business model is non-commercial, focusing on public service and digital inclusion. The partnership ecosystem includes the Ministry of Management and Innovation in Public Services, the Ministry of Human Rights and Citizenship, and the Federal University of Paraíba, indicating strong institutional support. The site supports government digital transformation and accessibility mandates, enhancing the inclusivity of public digital services. Market positioning is strong within the government sector, with no direct commercial competitors. The project benefits from official branding and trust signals, but could improve user engagement by providing clearer contact and policy information.

Security posture

The website enforces HTTPS and uses Google Tag Manager for analytics, indicating a baseline security posture. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published security policies, incident response contacts, or vulnerability disclosure mechanisms limits transparency and readiness for security incidents. Overall, the security maturity is moderate, suitable for a government informational site but with room for improvement in policy publication and header implementation.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit consent mechanisms to improve privacy compliance.
  2. Implement and configure standard security headers (CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy) to enhance security posture.
  3. Provide clear contact information including security incident response contacts and data protection officer details to improve transparency.
  4. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.

Technical notes

Notes

The website is built on the Plone CMS platform, leveraging jQuery and other JavaScript libraries such as Swiper.js and Font Awesome for UI components. It uses Google Tag Manager for analytics and tracking. The hosting appears to be managed by SERPRO, a Brazilian government IT service provider, as indicated by the nameservers. The site is mobile optimized and includes accessibility features consistent with its mission. Performance is moderate, with no major issues detected in the HTML content. The use of structured data (JSON-LD) enhances SEO and semantic clarity. Technical debt appears low, but improvements in security header implementation and policy publication are recommended to reduce technical risks.
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.
