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

Registro.br is the official Brazilian domain registry service managed by NIC.br, responsible for registering and managing .br domain names. It serves individuals and organizations in Brazil seeking to establish their online presence with Brazilian domain extensions. The website provides domain search, registration, and management services, emphasizing security features such as DNSSEC and fraud awareness. The site is well-branded, consistent, and professionally presented, reflecting its authoritative market position as the primary .br domain registry. Technically, the website employs modern web technologies including Vue.js and ES modules, with responsive design and good SEO practices. While performance is moderate, the site is optimized for mobile devices and accessibility is basic but functional. Security posture is strong with HTTPS enforced and fraud warnings present, though explicit security headers and incident response contacts could be improved. Privacy compliance is supported by a comprehensive privacy policy, though cookie consent mechanisms are absent. Overall, Registro.br demonstrates a mature digital infrastructure and a high level of trustworthiness aligned with its critical role in Brazil's internet ecosystem. The domain registration data corroborates the legitimacy and consistency of the service. Strategic improvements in security headers, incident response transparency, and cookie consent would further enhance the site's security and compliance 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.

Priority findings

5 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 holds a dominant position as the official .br domain registry, operated under NIC.br and overseen by CGI.br, Brazil's internet governance committee. Its business model centers on domain registration services with a fixed annual fee, targeting a broad audience from individuals to enterprises within Brazil. The organization benefits from strong institutional backing, ensuring trust and stability in the market. Its partnership ecosystem includes multiple Brazilian internet and technology organizations, reinforcing its authoritative role. The website content and structure support user education and fraud prevention, indicating a strategic focus on customer trust and service reliability.

Security posture

The website exhibits a solid security foundation with HTTPS enforced and DNSSEC support highlighted, which protects domain name integrity. Fraud warnings and guidance on identifying illegitimate charges demonstrate proactive security awareness. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. No incident response or abuse contact information is publicly visible, which could delay response to security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is strong with a detailed privacy policy, but cookie consent mechanisms are lacking. Overall, the security posture is good but could be improved with enhanced headers and transparency.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen protection against common web attacks.
  2. Publish clear incident response and abuse contact information to facilitate timely handling of security issues.
  3. Introduce a cookie consent banner or mechanism to comply with privacy regulations and enhance user trust.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Maintain and regularly update security practices and transparency to reinforce trust and compliance.

Technical notes

Notes

The website is built using modern web technologies, notably Vue.js with ES modules, enabling a single-page application experience. The use of module preload and scoped CSS indicates attention to performance optimization. Meta tags for SEO and social sharing (Open Graph and Twitter Cards) are well implemented. The site is mobile-optimized with responsive design and includes accessibility features such as skip links and ARIA labels, though these could be expanded. No CMS was detected, suggesting a custom or in-house developed platform. Hosting details are not explicit but the site uses official Brazilian domain infrastructure. Performance is moderate, likely due to JavaScript-heavy SPA architecture. Overall, the technical implementation is solid with room for incremental improvements in accessibility and security headers.
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.
