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

Luftfahrttechnisches Museum Rechlin e.V. is a small non-profit museum located in Germany, dedicated to the history and technology of aviation and military developments in the Rechlin region. The museum operates in historic buildings formerly used by the Luftwaffe and later Soviet forces, offering exhibitions on German and Soviet aviation, shipbuilding, and military history. It is supported by two volunteer associations and funded through entrance fees, donations, and memberships. The museum also engages in digital innovation through an augmented reality project funded by the German federal government. Technically, the website is built on the Contao CMS platform with Bootstrap and jQuery, providing a modern, mobile-optimized user experience. The site includes a cookie consent mechanism and basic SEO metadata but lacks advanced security headers and analytics tracking. Hosting appears to be managed via your-server.de, a known hosting provider. From a security perspective, the site uses HTTPS and implements cookie consent, but no explicit security or incident response policies are published. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data is minimal but consistent with a legitimate small non-profit entity. No WAF or blocking mechanisms interfere with content access. Overall, the website is professional, trustworthy, and suitable for its target audience of history and aviation enthusiasts. Recommendations include enhancing security headers, publishing security and incident response policies, and considering a vulnerability disclosure policy to improve trust and compliance.

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

7 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. 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 museum occupies a niche cultural and historical market segment focused on aviation and military history in the Rechlin region of Germany. Its business model relies on non-profit funding streams including entrance fees, donations, and memberships. The museum benefits from federal funding for digital projects, indicating some government support and recognition. Its partnership ecosystem includes cultural and governmental organizations. The website content and structure reflect a stable, community-oriented institution with a clear mission and audience. Growth opportunities may include expanding digital engagement and improving online presence. Competitive advantages include unique historical artifacts, a dedicated volunteer base, and federal funding support. The museum targets tourists, families, and aviation history enthusiasts. The absence of commercial advertising or analytics suggests a focus on privacy and user experience over monetization.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and a cookie consent mechanism in place. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security robustness. No incident response or security policy documentation is publicly available, which may limit preparedness for security incidents. No vulnerability disclosure or security contact information is provided, which could hinder responsible vulnerability reporting. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site does not appear to use analytics or tracking scripts that could introduce privacy risks. Overall, the security posture is adequate for a small non-profit museum website but could be improved by adopting best practices and transparency measures.

Recommendations

  1. Implement standard security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-XSS-Protection.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and preparedness.
  3. Establish a vulnerability disclosure policy and provide a security contact email (e.g., security@domain) to facilitate responsible reporting.
  4. Regularly update the CMS and all third-party libraries to mitigate potential vulnerabilities.
  5. Enhance SEO and accessibility features to improve user experience and reach.

Technical notes

Notes

The website uses a modern but basic technology stack centered on Contao CMS, Bootstrap, and jQuery. The site is mobile-optimized and includes interactive elements such as sliders and a cookie consent bar. Hosting is likely provided by your-server.de, a reputable German hosting provider. Performance is moderate with no obvious issues but could benefit from optimization. No advanced analytics or marketing tools are detected, aligning with the non-profit nature of the organization. The site lacks advanced security headers and some accessibility features, representing areas for technical improvement. Overall, the infrastructure supports the museum's informational and engagement goals effectively.
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.
