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

2 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.

    • 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. 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

TUHH operates as a public university focusing on technical education and research. Its market position is strong within the Hamburg region and Germany, serving a large audience of students and academics. The business model centers on providing degree programs, research initiatives, and technology transfer. Partnerships and international programs are evident, enhancing its ecosystem. The website supports various user groups with tailored content and services, indicating a mature digital strategy. Revenue streams likely include public funding, research grants, and tuition fees. The institution maintains a consistent brand and trust signals through official policies and structured content.

Security posture

The website enforces HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No incident response or vulnerability disclosure information is published, which is a gap in transparency and readiness. No vulnerable libraries or insecure scripts were detected. The absence of a cookie consent mechanism may pose GDPR compliance risks. Overall, the security posture is good but could be improved by adopting additional best practices and publishing security policies.

Recommendations

  1. Implement and publish a cookie consent mechanism to ensure GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish an incident response plan and vulnerability disclosure policy to improve transparency and trust.
  4. Include terms of service to clarify user rights and obligations.
  5. Regularly audit third-party scripts and update CMS and extensions to mitigate vulnerabilities.

Technical notes

Notes

The website uses TYPO3 CMS, a robust and widely used open-source content management system, indicating a stable technical foundation. JavaScript and CSS assets are well organized and loaded efficiently. The site includes Google Custom Search Engine integration for enhanced search capabilities. Mobile optimization is good, with responsive design elements and accessibility considerations. Performance is moderate, with potential for optimization in asset loading and caching. No deprecated or vulnerable libraries were detected in the provided scripts. The hosting provider is not explicitly identified, but the use of DFN name servers suggests academic network hosting. Overall, the technical infrastructure supports a professional and user-friendly experience.
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.
