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

Stiftung Kunst und Natur is a German non-profit foundation focused on fostering interdisciplinary engagement with art, culture, nature, and landscape. It operates at two main locations: Nantesbuch in Bavaria and the Museum Sinclair-Haus in Bad Homburg. The foundation offers cultural events, workshops, and environmental conservation activities, targeting art and nature enthusiasts as well as the regional community. The website reflects a professional and consistent brand image with good content quality and clear navigation. Technically, the site uses modern JavaScript libraries, integrates Google Analytics for visitor insights, and employs Cookiebot for GDPR-compliant cookie consent management. Security posture is solid with HTTPS and error tracking, though additional security headers could enhance protection. Privacy compliance is well addressed with accessible policies and consent mechanisms. However, no explicit contact information or terms of service were found, which could be improved to enhance business credibility.

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 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. 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The foundation occupies a niche market segment combining cultural and environmental stewardship. Its business model is non-profit, focusing on community engagement and conservation. The partnership ecosystem includes related domains such as nantesbuch.de and stiftung-nantesbuch.de, indicating collaborative regional efforts. The website's content and structure suggest a small-sized organization with a clear mission but limited digital footprint in terms of direct contact channels. Growth opportunities may lie in expanding digital engagement and transparency. The use of third-party services like Google Analytics and Cookiebot indicates a moderate level of digital maturity.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of Rollbar for error monitoring with anonymized IP capture. Cookie consent is managed via Cookiebot, supporting GDPR compliance. However, the absence of several recommended security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) represents a gap that could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and security policy information are not publicly available, which limits transparency and readiness perception. Overall, the security posture is adequate but could be strengthened with additional controls and documented policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish clear terms of service and incident response contact information to improve transparency and trust.
  3. Add explicit contact details such as company email and phone number to facilitate user communication and enhance credibility.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Consider establishing a publicly accessible security policy and vulnerability disclosure program to align with best practices.

Technical notes

Notes

The website is built with modern web technologies including JavaScript, CSS3, and HTML5. It uses Rollbar for client-side error tracking and Google Analytics for visitor analytics. Cookiebot manages cookie consent, ensuring GDPR compliance. Images are lazy-loaded for performance optimization. The site appears mobile-optimized with responsive design elements. SEO is supported by appropriate meta tags and Open Graph data. However, no CMS or hosting provider details were detected. Performance is moderate, with potential for improvement in loading speed and accessibility features. The technical infrastructure supports the foundation's mission but could benefit from enhanced security configurations and more detailed technical documentation.
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.
