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

6 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 CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 foundation operates in the education and non-profit sectors, focusing on listening education for children and educators. Its business model revolves around providing training and educational resources, likely funded through grants, donations, or public funding. The website's clear branding and consistent messaging support its niche positioning. Partnerships with platforms like LearningApps.org and media entities like Bayerischer Rundfunk suggest a collaborative ecosystem. The absence of commercial advertising or affiliate programs aligns with its non-profit status. The foundation targets educators and institutions, emphasizing quality content and compliance with data protection laws, which enhances trust and credibility in its market segment.

Security posture

The website exhibits a moderate to good security posture with HTTPS enabled and a robust cookie consent framework that respects GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of security headers such as Content-Security-Policy and HSTS reduces the overall security score. There is no visible incident response or security policy page, which could be a gap in transparency and preparedness. The use of up-to-date plugins and WordPress core is assumed but should be regularly audited. Overall, the site maintains a secure environment suitable for its audience but would benefit from enhanced security controls and documentation.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the site against common web attacks.
  2. Enable HTTP Strict Transport Security (HSTS) to enforce HTTPS usage and prevent protocol downgrade attacks.
  3. Develop and publish a dedicated security policy and incident response page to improve transparency and preparedness.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Consider adding accessibility improvements to enhance usability for all users.

Technical notes

Notes

The website is built on WordPress with the Divi theme, leveraging popular plugins such as Yoast SEO for search optimization and Real Cookie Banner Pro for GDPR-compliant cookie management. It integrates external services like Vimeo and YouTube for media content and uses Matomo for privacy-focused analytics. The site loads resources from reputable CDNs including jsDelivr and Google Fonts. Performance is moderate with good mobile optimization and basic accessibility features. The technical setup reflects a modern, well-maintained infrastructure suitable for a non-profit educational organization. Opportunities exist to improve security headers and accessibility compliance to further enhance the technical robustness.
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.
