Stadtmuseum Aarau is a Swiss cultural institution dedicated to collecting, conserving, and presenting the history and stories of the city of Aarau and its population. It serves a broad audience including families, schools, and local visitors by offering exhibitions, events, educational programs, and digital content. The museum operates under the auspices of the city of Aarau, positioning itself as a trusted local government-affiliated entity with a clear cultural mission. Technically, the website is built on the GOViS CMS platform, a Swiss eGovernment content management system, and employs modern web technologies such as jQuery, Font Awesome, and Matomo analytics. The site is well-optimized for mobile devices and accessibility, with good SEO practices and a clear navigation structure. Security-wise, the website enforces HTTPS and uses a comprehensive cookie consent mechanism, though it lacks explicit security headers and a published security policy or incident response contact. Overall, the site demonstrates a solid security posture with no visible vulnerabilities or suspicious content.

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

3 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

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

The Stadtmuseum Aarau operates as a small government-affiliated cultural institution focused on heritage preservation and public education. Its business model revolves around providing museum exhibitions, events, and educational services to local residents, schools, families, and cultural tourists. The museum leverages partnerships with the city of Aarau and uses the GOViS CMS platform, indicating integration with Swiss eGovernment digital infrastructure. Revenue streams likely include public funding, event fees, and possibly donations or memberships. The institution maintains a clear and consistent brand presence with trust signals such as official contact details and privacy compliance. Growth indicators include active event programming and digital engagement initiatives like stadtmuseum@home. The museum's partnership ecosystem includes the city government and digital service providers like backslash AG and GOViS. Overall, the museum holds a stable position in the local cultural sector with opportunities to enhance digital and security maturity.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and a robust cookie consent framework that respects user privacy and GDPR compliance. The use of Matomo analytics configured with secure cookies and consent tracking further supports privacy-conscious data collection. However, the absence of explicit HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options represents an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency and readiness for security incidents. There is no evidence of a vulnerability disclosure program or security.txt file. Overall, the site is secure for its purpose but could benefit from enhanced security controls and formalized incident response communication to align with best practices and regulatory expectations.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact information to improve transparency and preparedness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance user trust by providing more visible trust indicators such as certifications or testimonials.

Technical notes

Notes

The website is built on the GOViS CMS platform, a Swiss eGovernment content management system, ensuring compliance with local digital governance standards. It uses modern JavaScript libraries including jQuery 3.7.1 and Font Awesome 4.7.0 for UI elements, and Magnific Popup for media display. The site integrates Matomo analytics for privacy-respecting visitor tracking. Performance is moderate with good mobile optimization and accessibility features such as skip links and ARIA attributes. SEO is supported by proper meta tags, Open Graph, and Twitter card metadata. The cookie consent mechanism is implemented using the c-consent library with granular categories and user controls. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is solid with opportunities to improve security headers and performance optimizations.
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.
