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

Schule Muhen is a local educational institution based in Muhen, Switzerland, providing primary and secondary education services along with additional offerings such as music school and educational support. The website serves parents, students, teachers, and the local community, offering information about school organization, events, and services. It is positioned as a trusted community school with a clear focus on education and local engagement. Technically, the website is built on the GOViS CMS platform, a Swiss eGovernment content management system, and utilizes modern libraries such as jQuery, Font Awesome 6 Pro, and Swiper for UI components. The site is mobile-optimized, accessible, and SEO-friendly, with a moderate performance profile. Privacy compliance is well addressed with a comprehensive privacy and cookie policy and an active cookie consent mechanism. From a security perspective, the site enforces HTTPS and uses Matomo for analytics with privacy considerations. However, it lacks explicit security headers and dedicated security or incident response policies. No vulnerabilities or suspicious activities were detected in the content or WHOIS data, which aligns well with the website's educational and community role. Overall, Schule Muhen presents a professional, trustworthy, and compliant online presence suitable for its audience. Strategic improvements in security headers and incident response documentation could further enhance its security posture and trustworthiness.

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

  4. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

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

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.

Business context

Business profile

Schule Muhen operates as a public educational institution serving the Muhen community in the canton of Aargau, Switzerland. Its business model is focused on providing comprehensive education from primary through secondary levels, supplemented by additional services such as music school and social support. The institution targets local families, students, and educators, positioning itself as a key community resource. The website reflects a stable, small-sized organization with no indication of subsidiaries or parent companies. Partnerships with local government and eGovernment CMS providers indicate integration within the Swiss public sector ecosystem. The content and navigation structure support transparency and accessibility, reinforcing community trust and engagement.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism in place, reflecting GDPR compliance. The use of Matomo analytics is privacy-conscious, and no sensitive data exposure was found. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security represents an area for improvement. No explicit incident response or security policy pages were found, which could limit preparedness for security incidents. The WHOIS data is consistent and transparent, supporting domain legitimacy. Overall, the security posture is adequate for a public educational website but could benefit from enhanced security controls and documentation.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to strengthen defense against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness for security events.
  3. Regularly update and audit third-party libraries and dependencies to mitigate vulnerabilities.
  4. Enhance monitoring and logging capabilities to detect and respond to potential security incidents promptly.
  5. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.

Technical notes

Notes

The website leverages a modern technology stack with GOViS CMS, jQuery 3.7.1, Font Awesome 6 Pro icons, and Swiper for interactive UI elements. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured navigation. Performance is moderate, with room for optimization in image loading and script management. The use of Matomo analytics indicates a preference for privacy-respecting tools. No major technical debt or outdated technologies were detected. Opportunities exist to improve security headers and enhance incident response capabilities 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.
