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

10 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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 · found on this site
  • 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

The institution operates in the non-profit cultural sector with a niche focus on metallurgy and materials heritage. It is supported by government cultural ministries and sponsors, positioning itself as a specialized cultural hub in São Paulo. The business model relies on sponsorships and public funding, with a strong emphasis on educational and cultural programming. The website reflects a consistent brand and trust signals such as Ministry of Culture endorsement and ABM certification. Social media integration is robust, enhancing outreach and engagement. Growth opportunities include expanding digital accessibility and enhancing compliance with privacy regulations.

Security posture

The website uses HTTPS and modern WordPress plugins, which provide a baseline security level. However, the absence of key security headers like Content-Security-Policy and Strict-Transport-Security reduces its defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the provided content. The lack of a vulnerability disclosure policy or security.txt file suggests limited incident response readiness. Privacy compliance is partial, with no cookie consent mechanism or detailed privacy policy. Enhancing these areas would improve the security posture and regulatory compliance.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Add a clear and detailed privacy policy and cookie consent mechanism to comply with GDPR and other privacy regulations.
  3. Establish a vulnerability disclosure policy or security.txt file to improve incident response and transparency.
  4. Regularly update WordPress core and plugins to mitigate potential vulnerabilities.
  5. Enhance SEO and accessibility features to improve user experience and reach.

Technical notes

Notes

The website is built on WordPress 6.8.2 with a modern tech stack including jQuery, Google Fonts, Font Awesome, and specialized plugins for event management and galleries. Hosting is provided by Locaweb, a reputable Brazilian hosting provider. Performance is moderate with good mobile optimization and accessibility features such as the VLibras plugin for sign language translation. SEO is basic but present with meta tags and structured data for events. There is no evidence of technical debt or deprecated technologies. Opportunities exist to improve security headers and privacy compliance to modern standards.
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.
