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

The Würzburg-Dresden Cluster of Excellence ct.qmat is a prominent academic research center specializing in topological and complex quantum matter. Established in 2019, it unites leading research hubs from Universität Würzburg and Technische Universität Dresden, focusing on advancing quantum materials research, education, and public outreach. The website reflects a professional and well-maintained digital presence with comprehensive content targeted at researchers, students, and the interested public. Technically, the site employs modern web standards, responsive design, and uses Matomo analytics for privacy-conscious tracking. Security posture is strong with HTTPS enforced and no visible vulnerabilities, though explicit security policies and incident response contacts are absent. Privacy compliance is good with a clear privacy policy but lacks a cookie consent mechanism. Overall, the site is trustworthy and authoritative within its academic domain.

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

10 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

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

ct.qmat holds a leading position in the academic research sector for quantum materials, leveraging partnerships with major German research institutions and international collaborators. Its business model is grant-funded academic research with a focus on innovation, education, and outreach. The cluster's network includes universities, Max Planck Institutes, and other research centers, enhancing its competitive advantage. The website supports this ecosystem by providing detailed information on research areas, events, news, and career opportunities, indicating active engagement with the scientific community and potential recruits. The absence of commercial advertising and affiliate programs aligns with its non-commercial academic nature.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. Security headers are likely implemented though not explicitly confirmed. No vulnerable or outdated libraries were detected in the scripts. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms represents a compliance gap. The site does not appear to collect sensitive personal data directly on the homepage, reducing risk exposure. Overall, the security posture is solid but could be enhanced by formalizing security governance documentation and user guidance.

Recommendations

  1. Implement a cookie consent banner to comply fully with GDPR cookie regulations.
  2. Publish a dedicated security policy page and provide incident response contact information.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Review and enforce Content-Security-Policy headers to mitigate cross-site scripting risks.
  5. Enhance transparency by including terms of service or user agreements relevant to site usage.

Technical notes

Notes

The website uses a modern tech stack including HTML5, CSS3, JavaScript libraries such as MathJax and Slick Slider, and Font Awesome icons. The CMS is likely TYPO3, common in academic institutions. Hosting is via academic networks with DNS servers linked to Universität Würzburg and DFN, indicating stable and secure infrastructure. Performance is moderate with responsive design and good accessibility features. SEO is well addressed with proper meta tags and Open Graph data. No major technical debts or deprecated technologies were detected. Opportunities exist to improve performance optimization and implement advanced security headers.
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.
