Risk levelHigh

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

Museum Kunststätte Bossard is a small non-profit cultural institution in Germany dedicated to preserving and showcasing the artistic legacy of Johann and Jutta Bossard. The website provides detailed information about exhibitions, guided tours, and visitor services, targeting art enthusiasts and the general public. The museum operates with a clear cultural mission and maintains a consistent brand presence online. Technically, the website uses a traditional CMS (Contao) with common JavaScript libraries and moderate performance and mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and published policies. Privacy compliance is partial with a privacy policy present but no cookie consent mechanism. Overall, the site is trustworthy and professionally maintained, though improvements in security and privacy transparency are recommended.

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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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';…

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 museum holds a niche position in the cultural sector, focusing on a unique Gesamtkunstwerk by the Bossard couple. Its business model is non-profit, relying on public visitors, memberships, and cultural programming. The website supports this with clear contact info, event announcements, and digital engagement via social media and a museum app. The institution appears stable with a focused target audience and regional cultural significance. Partnerships include digital museum app providers. There is no indication of commercial subsidiaries or complex corporate structure.

Security posture

The website benefits from HTTPS and absence of obvious vulnerabilities or exposed sensitive data. However, it lacks security headers such as CSP and X-Frame-Options, and no incident response or security policy is published. No vulnerability disclosure or security.txt is found. The JavaScript libraries used are somewhat outdated (e.g., jQuery 2.2.4). The site does not implement cookie consent mechanisms, which is a GDPR compliance gap. Overall security maturity is moderate but could be improved with standard best practices and transparency.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR requirements.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Update JavaScript libraries to current supported versions to reduce vulnerability risks.
  5. Enhance accessibility features and mobile optimization for better user experience and compliance.

Technical notes

Notes

The website is built on Contao CMS and uses a combination of jQuery, Bootstrap, and other UI libraries. The tech stack is somewhat dated but functional. Hosting is via rzone.de, a German hosting provider. Performance is moderate with some optimization opportunities. SEO is basic with meta tags present but no Open Graph or JSON-LD structured data detected. Accessibility is basic with skip navigation links but no advanced ARIA roles or landmarks. The site is mobile responsive but could improve in usability and speed.
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.
