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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  3. 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

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

Ceweb.br holds a strong position in Brazil's internet governance ecosystem as a department of NIC.br, collaborating closely with CGI.br and other national internet organizations. Its competitive advantage lies in its authoritative role in web technology research, accessibility standards development (notably the ABNT NBR 17225 standard), and open data initiatives. The business model is non-commercial, focusing on community service, education, and policy support. Revenue streams are likely government or institutional funding. Target customers include Brazilian internet stakeholders, developers, and public institutions. Growth indicators include ongoing projects, courses, and active social media engagement. The partnership ecosystem is robust, involving multiple Brazilian internet governance bodies and international standards organizations like W3C. Strategic observations highlight the organization's role as a trusted knowledge hub and policy influencer in Brazil's digital landscape.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS usage and no visible exposure of sensitive data. The use of secure external scripts and analytics tools is appropriate. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security reduces the overall security hardening. No explicit incident response or vulnerability disclosure mechanisms are publicly available, which could hinder rapid response to security events. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent banner. The lack of contact emails or phone numbers for security incidents limits direct communication channels. Overall, the security maturity is good but could be improved by adopting additional security headers, publishing incident response policies, and establishing vulnerability disclosure processes.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness for security events.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance form security by integrating CAPTCHA or other anti-bot mechanisms beyond MailChimp validation to reduce spam and abuse.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations such as GDPR and LGPD.

Technical notes

Notes

The website is built on a solid technical foundation using HTML5, CSS3, Bootstrap framework, and JavaScript libraries like jQuery and Owl Carousel for UI components. FontAwesome is used for iconography. The site integrates MailChimp for newsletter subscription and Piwik (Matomo) for analytics, indicating a focus on user engagement and data-driven insights. The site is mobile responsive and accessible, with good SEO meta tags and Open Graph data for social media sharing. Performance is moderate, with no major issues detected. There is no evidence of a CMS, suggesting a custom or static site architecture. Hosting provider details are not explicitly available. Technical risks are minimal but could include outdated libraries if not regularly updated. Opportunities exist to modernize analytics and marketing tools and improve security configurations.
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.
