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

Museum Huelsmann is a cultural institution located in Bielefeld, Germany, specializing in applied arts with a diverse collection displayed in a historic villa. The museum offers exhibitions, special events, workshops, and an online ticketshop, positioning itself as a young but quality art museum in Germany. The website is professionally designed with clear navigation and content relevant to its audience, primarily German-speaking visitors interested in art and culture. Technically, the site uses standard web technologies such as jQuery and Fancybox, hosted with DomainControl (GoDaddy), and employs HTTPS for secure communication. The cookie consent mechanism is implemented, supporting GDPR compliance. Security posture is moderate with HTTPS enabled but lacks advanced security headers and explicit incident response policies. Overall, the site is trustworthy, safe, and well-maintained, with room for improvements in mobile optimization and security best practices.

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. 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';…

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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.

Dark web exposure

Add-on

Leaked records that mention museumhuelsmann.de, from OffSeq Breach.

No leaked records found

Breach holds no records for museumhuelsmann.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

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 operates in the cultural and educational sector, targeting general audiences including art enthusiasts, educators, and families. Its business model revolves around exhibitions, educational workshops, and ticket sales, with partnerships such as the external ticketing platform pretix.eu. The museum's market position is that of a specialized, quality institution with a focus on applied arts and modern collections. The website supports its business by providing event information, online ticket purchasing, and social media engagement. Growth potential lies in expanding digital offerings and improving mobile user experience. The museum maintains a consistent brand image and leverages social media channels to enhance visibility.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is properly implemented, ensuring encrypted communication. A cookie consent banner is present, indicating awareness of privacy regulations. However, the absence of security headers like Content-Security-Policy and lack of a published security policy or incident response contact reduce the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the provided content. The use of third-party libraries from reputable CDNs is noted, but regular updates and security audits are recommended. Incident response readiness and vulnerability disclosure mechanisms are not evident, which could be improved to enhance trust and compliance.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and readiness.
  3. Regularly update all third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance mobile optimization and accessibility to improve user experience across devices.
  5. Consider integrating analytics with privacy-respecting configurations to better understand user behavior while maintaining compliance.

Technical notes

Notes

The website uses a traditional web technology stack with jQuery and Fancybox for UI components, served over HTTPS with assets loaded from CDNJS. The hosting provider is DomainControl (GoDaddy), a common registrar and DNS provider. The site has moderate performance and basic mobile responsiveness. SEO is supported by meta tags and Open Graph data but could be improved with structured data like JSON-LD. Accessibility features are minimal but present. The site does not appear to use a CMS or modern JavaScript frameworks. There is technical debt in the form of legacy scripts and limited security headers. Opportunities exist to modernize the tech stack, improve performance, and enhance security configurations.
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.
