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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The school operates as a public educational entity under local municipal governance, targeting children and families in the Biberstein community. Its business model is non-commercial, focusing on education and community services. The website reflects a strong local presence and partnership ecosystem including the municipality and service providers like GOViS and backslash AG. The institution's market position is stable within its niche, emphasizing inclusivity and community integration. Growth indicators are limited due to the nature of the institution but the site supports transparency and engagement with stakeholders.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a cookie consent mechanism that respects user privacy. Use of Matomo analytics is privacy-conscious with opt-in consent and cookie auto-clearance. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected. The site would benefit from formalizing vulnerability disclosure and incident response contact channels to enhance trust and readiness.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  3. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly review and update third-party libraries and dependencies to avoid potential vulnerabilities.
  5. Enhance website performance monitoring and optimize loading times for better user experience.

Technical notes

Notes

The website uses a modern technology stack centered around the GOViS eGovernment CMS platform, leveraging jQuery 3.7.1, Font Awesome 4.7.0, and Magnific Popup for UI enhancements. The site is mobile-optimized with responsive design and accessibility features. SEO best practices are followed with proper meta tags and canonical URLs. Analytics are handled via Matomo with privacy-respecting configurations. Hosting details are not explicitly disclosed but the site is served over HTTPS with a valid certificate. Performance is moderate with room for optimization. No technical debt or deprecated technologies were detected.
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.
