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. 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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"

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 university holds a strong market position in German higher education, leveraging its Exzellenzuniversität status to attract students and researchers. Its business model centers on public education and research funding, supported by international partnerships such as the European University for Well-Being. The website's content and navigation cater effectively to its academic audience, with clear calls to action for applications and research engagement. The presence of multiple social media channels and event listings indicates active community engagement and outreach.

Security posture

The website employs HTTPS with a good SSL configuration and uses secure POST forms for user authentication. No sensitive data is exposed in the HTML content. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published security or incident response policies represent areas for enhancement. The use of Piwik with disabled cookies shows privacy-conscious analytics deployment. No vulnerabilities or suspicious indicators were detected in the content or scripts.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Deploy a clear cookie consent banner/mechanism to comply fully with GDPR cookie requirements.
  3. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  4. Consider adding a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is powered by TYPO3 CMS with multiple extensions and uses jQuery 1.11.2 and jQuery UI, which are somewhat dated but still functional. The site includes modern UI components like Owl Carousel and Magnific Popup for enhanced user experience. Analytics are handled via Piwik/Matomo with cookies disabled, reflecting privacy awareness. Performance is moderate with good mobile optimization and accessibility features. The site lacks some modern security headers and explicit cookie consent mechanisms, which are recommended for compliance and security hardening.
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.
