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

Registro.br is the official Brazilian domain registry responsible for managing .br domain registrations. Operated by NIC.br, it serves individuals and organizations in Brazil seeking to register and manage their internet domain names under the .br country code. The website provides domain search, registration, and management services, along with educational resources and security awareness content. The site is well-positioned as a trusted authority in the Brazilian internet ecosystem, supported by partnerships with CGI.br and CERT.br. Technically, the website employs modern web technologies including Vue.js and JavaScript ES modules, ensuring a responsive and performant user experience. The site is mobile-optimized, accessible, and SEO-friendly, with clear navigation and professional design. Security best practices are observed with HTTPS enforcement and secure form handling, although some security headers could be improved. Privacy compliance is strong with a comprehensive privacy policy, though cookie consent mechanisms are absent. From a security perspective, the domain registration details align with the official registry, showing high legitimacy and no suspicious patterns. No vulnerabilities or exposed sensitive data were detected. However, the site lacks explicit incident response contact information and vulnerability disclosure policies, which could enhance trust and security posture. Overall, Registro.br presents a high-quality, trustworthy, and professional web presence suitable for its critical role in Brazil's internet infrastructure. Strategic improvements in security headers, cookie consent, and incident response transparency would further strengthen its security and compliance profile.

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.

Priority findings

6 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  3. 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

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

Registro.br operates as the essential national domain registry for Brazil, holding a monopoly on .br domain registrations. Its business model is service-oriented, funded likely through domain registration fees (noted as R$ 40,00 per year). The target audience includes Brazilian businesses, government entities, and individuals requiring domain registration. The organization benefits from strong government and multistakeholder backing via NIC.br and CGI.br, positioning it as a key player in Brazil's internet governance. The website's ecosystem includes partnerships with security and internet governance bodies, enhancing its credibility and operational reach. Growth indicators include educational content and outreach via events and tutorials. The lack of direct contact info on the homepage suggests a structured support system likely accessible through authenticated user accounts or subpages.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible security vulnerabilities or exposed sensitive data. The use of modern JavaScript frameworks and secure form inputs indicates attention to secure development practices. However, the absence of explicit security headers like Content-Security-Policy and lack of published incident response or vulnerability disclosure policies represent areas for improvement. No cookie consent mechanism was detected, which may be a compliance gap under privacy regulations. The WHOIS data confirms domain legitimacy and consistency with the official registry, reducing risk of phishing or spoofing. Overall, the security maturity is high but could benefit from enhanced transparency and additional security controls.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Add a visible cookie consent banner to comply with privacy regulations and improve user trust.
  3. Publish a dedicated security policy and incident response page with clear contact channels for reporting security issues.
  4. Consider creating and publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance user support accessibility by providing clear contact information on the public site or within user portals.

Technical notes

Notes

The website is built using a modern JavaScript framework (Vue.js) with modular JavaScript and CSS assets, indicating a contemporary front-end architecture. The use of SVG icons and responsive design elements supports excellent mobile optimization and accessibility. The site loads quickly and includes proper meta tags for SEO and social sharing (Open Graph and Twitter cards). No third-party advertising or tracking scripts were detected, suggesting a privacy-conscious approach. The hosting provider is not explicitly identified, but the domain uses official Brazilian DNS servers consistent with NIC.br operations. Overall, the technical implementation is robust, modern, and well-maintained, with opportunities to improve security headers and privacy mechanisms.
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.
