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 local hub for disseminating information about web standards, accessibility, and related publications, targeting web professionals, developers, and accessibility advocates primarily in Brazil. It maintains strong affiliations with Brazilian internet governance bodies such as NIC.br and CGI.br, reinforcing its credibility and local relevance. Technically, the website is built on WordPress, leveraging Bootstrap for responsive design and jQuery for interactivity. The site demonstrates moderate performance and good mobile optimization, with structured data implemented for SEO benefits. However, it lacks some advanced security headers and explicit cookie consent mechanisms, which could be improved to enhance privacy compliance and security posture. From a security perspective, the site uses HTTPS and does not expose sensitive data in its HTML content. There is no evidence of a published security policy or incident response contact, which are areas for potential enhancement. The WHOIS data aligns well with the website's stated purpose and affiliations, indicating a legitimate and trustworthy domain registration. Overall, the website is professional, content-rich, and trustworthy, with room for improvement in privacy compliance and security best practices to meet higher standards and regulatory requirements.

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 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 Capítulo São Paulo operates as a non-profit consortium chapter focused on advancing web standards and accessibility in Brazil. Its market position is strong within the technology and non-profit sectors, leveraging partnerships with key Brazilian internet organizations. The business model centers on community engagement, education, and standards promotion rather than commercial revenue. The target audience includes web developers, government entities, accessibility professionals, and the general public interested in web technologies. The organization benefits from a stable domain registration and recognized affiliations, supporting its growth and influence in the local web ecosystem.

Security posture

The website exhibits a moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. However, the absence of security headers such as Content-Security-Policy and lack of a published security or incident response policy indicate gaps in security best practices. No vulnerabilities or malicious scripts were detected in the HTML content. Privacy compliance is partial, with no cookie consent mechanism observed. The site would benefit from enhanced security controls, formalized policies, and improved privacy disclosures to align with GDPR and other regulations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a clear cookie consent banner/mechanism to improve GDPR compliance.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Conduct regular security audits of third-party plugins and scripts to mitigate vulnerabilities.
  5. Enhance accessibility features and privacy disclosures to strengthen user trust and compliance.

Technical notes

Notes

The website is built on a WordPress CMS platform using Bootstrap for responsive design and jQuery for client-side scripting. It employs Google Fonts and FontAwesome for typography and icons. The site demonstrates good mobile optimization and SEO practices, including structured data in JSON-LD format. Performance is moderate, with no critical technical debt observed. Hosting appears to be managed by NIC.br or associated Brazilian internet infrastructure providers. Opportunities exist to modernize security configurations and implement advanced privacy features to reduce technical risks.
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.
