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

The website w3c.br represents the São Paulo chapter of the World Wide Web Consortium (W3C), a globally recognized non-profit organization dedicated to developing and promoting web standards. The site serves as a community hub providing information on web standards, accessibility initiatives, and related publications primarily targeting web developers, technology professionals, and accessibility advocates in Brazil. It maintains a strong affiliation with Brazilian internet governance bodies such as NIC.br and CEWEB, reinforcing its legitimacy and local presence. Technically, the website is built on WordPress CMS, leveraging modern front-end technologies including Bootstrap, jQuery, and FontAwesome. The site demonstrates good mobile optimization, accessibility, and SEO practices, although performance is moderate. The presence of structured data (JSON-LD) and Open Graph metadata enhances search engine visibility and social media integration. From a security perspective, the site uses HTTPS (implied by domain and best practices), but lacks explicit security headers and published security policies or incident response contacts. No cookie consent mechanism was detected, which may impact privacy compliance. The domain registration data is consistent and legitimate, with no privacy protection masking ownership, and the domain is registered through NIC.br with an expiry in 2025. Overall, the website is professional, trustworthy, and well-positioned within its niche. However, improvements in security headers, privacy compliance mechanisms, and incident response transparency would enhance its security posture and regulatory adherence.

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

8 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 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

    • 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

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

W3C São Paulo chapter operates as an important non-profit entity within the technology sector, focusing on web standards and accessibility. Its market positioning is strong due to its affiliation with the global W3C consortium and local Brazilian internet authorities. The business model is community and standards-driven rather than commercial, relying on partnerships and collaborations. The target audience includes web developers, government entities, educational institutions, and accessibility advocates. The partnership ecosystem includes NIC.br, CEWEB, and CGI.br, which are critical for infrastructure and outreach. The website content and structure indicate a medium-sized organization with a focus on education, standards dissemination, and community engagement.

Security posture

The current security posture is moderate. The site uses HTTPS, which is mandatory for secure communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No security.txt or vulnerability disclosure policy is published, limiting transparency and incident response readiness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a cookie consent mechanism may pose compliance risks under GDPR or similar regulations. Overall, the site demonstrates basic security hygiene but would benefit from enhanced security controls and documented policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to mitigate common web vulnerabilities.
  2. Add a cookie consent banner or mechanism to comply with privacy regulations and improve user transparency.
  3. Publish a formal security policy and incident response contact information to enhance trust and preparedness.
  4. Conduct regular security audits to identify and remediate any vulnerable libraries or outdated components.
  5. Enhance privacy compliance by appointing or disclosing a Data Protection Officer and updating privacy policies accordingly.

Technical notes

Notes

The website is built on a WordPress platform using a modern tech stack including Bootstrap for responsive design, jQuery for scripting, and FontAwesome for icons. It uses Google Fonts for typography and The SEO Framework plugin for SEO optimization. The site is mobile optimized and accessible with good navigation clarity. Performance is moderate, likely due to standard WordPress overhead and external font loading. Hosting appears to be managed by NIC.br or related Brazilian infrastructure providers, ensuring local reliability. There is no evidence of advanced caching or CDN usage in the HTML content. Technical debt appears low, but opportunities exist to improve security headers and privacy compliance 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.
