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

7 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, LinkedIn, YouTube

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

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

Ceptro.br holds an important position in Brazil's Internet technology sector, focusing on research, education, and quality measurement initiatives. Its business model is non-profit and educational, targeting network operators, researchers, and students. The organization benefits from partnerships with NIC.br, CGI.br, and other Brazilian Internet governance entities, enhancing its credibility and reach. The website serves as a hub for projects, courses, and events, supporting community engagement and knowledge dissemination. Growth indicators include active event scheduling and multiple ongoing projects. The partnership ecosystem is robust, linking to key national Internet institutions.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enabled, ensuring encrypted communication. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is published, which could hinder timely security issue reporting. No forms are present on the homepage, reducing attack surface. The lack of privacy and cookie policies indicates compliance gaps, especially regarding GDPR and similar regulations. Overall, the security posture is adequate but could be significantly improved with policy publication and header implementation.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide explicit contact information for security incidents and general inquiries.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built using standard web technologies including HTML5, Bootstrap for responsive design, jQuery for scripting, and FontAwesome for icons. The site is mobile optimized with a clear navigation structure and professional design. Performance is moderate, with scripts loaded at the end of the document to improve load times. No CMS or hosting provider information is explicitly detected. SEO optimization is basic with minimal meta description content. No analytics or tracking scripts were found, indicating minimal user tracking. The technical implementation is solid but could benefit from enhanced SEO and accessibility improvements.
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.
