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

Museum Giersch der Goethe-Universität is a small, university-affiliated cultural institution based in Frankfurt am Main, Germany. The museum focuses on art exhibitions, educational workshops, and cultural events, serving a broad audience including students, researchers, and the general public. The website reflects a professional and consistent brand image, with clear navigation and multilingual support via a translation widget. The institution operates a museum shop and offers guided tours and lectures, positioning itself as a regional cultural hub with strong ties to Goethe University. Technically, the website is built on WordPress CMS, utilizing modern JavaScript libraries such as jQuery and Swiper.js for interactive elements. It employs Borlabs Cookie for GDPR-compliant cookie consent management and integrates Google reCAPTCHA to secure forms. Hosting is provided by kasserver.com, and the site uses HTTPS with good SSL configuration. While security headers are not explicitly detected, the site follows basic security best practices. The website is mobile-optimized and performs moderately well, with room for improvement in accessibility and security header implementation. From a security perspective, the site demonstrates a reasonable posture with encrypted connections, form protection, and cookie consent. However, it lacks a published security policy, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or suspicious content were detected. Privacy compliance is strong, with a comprehensive privacy policy and cookie management. Contact information is complete and transparent, enhancing trustworthiness. Overall, the website is a well-maintained, secure, and privacy-conscious platform for a university museum. Strategic recommendations include enhancing security headers, publishing a security policy, and considering a vulnerability disclosure policy to further strengthen security posture and trust. The site is safe for general audiences and does not contain any adult or questionable 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

8 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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';…

  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 · found on this site
  • 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 Giersch der Goethe-Universität operates as a non-profit educational and cultural institution affiliated with Goethe University Frankfurt. Its market positioning is regional, targeting art enthusiasts, students, and the general public interested in cultural exhibitions and educational programming. The museum's business model centers on providing exhibitions, workshops, guided tours, and a museum shop, generating revenue through ticket sales and merchandise. The website supports multilingual access, indicating an inclusive approach to diverse audiences. The institution maintains active social media channels and a newsletter to engage its community. No direct partnerships or subsidiaries are evident from the website data. The museum's operations appear stable and focused on cultural education, with potential growth through enhanced digital engagement and expanded event offerings.

Security posture

The website exhibits a moderate security maturity level. HTTPS is enforced, and Google reCAPTCHA protects forms against automated abuse. Cookie consent is managed via Borlabs Cookie, supporting GDPR compliance. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security robustness. No security or incident response policies are published, limiting transparency in handling security events. The site does not expose sensitive data or use vulnerable libraries based on the analysis. The use of WordPress and common plugins necessitates regular updates to mitigate risks. Overall, the security posture is adequate for a cultural institution but can be improved by implementing recommended headers, publishing security policies, and establishing a vulnerability disclosure process.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience.

The technical stack is modern and appropriate for a small cultural institution, with opportunities to enhance security and accessibility further.
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.
