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

Technische Universität Hamburg (TUHH) is a compact technical university based in Hamburg, Germany, focused on providing modern, practice-oriented education and research in engineering and technology. The website reflects a well-established institution with a clear profile in research, education, and technology transfer, targeting students, researchers, staff, and international partners. The site offers comprehensive information on study programs, research initiatives, career services, and international collaborations, supported by a modern TYPO3 CMS infrastructure. The university maintains a strong brand presence with partner logos and certifications, indicating credibility and trust. From a technical perspective, the website uses TYPO3 CMS with modern frontend technologies, including JavaScript and CSS, delivering a good user experience with responsive design and accessibility features. Performance is moderate with a page load time around 3.8 seconds and a well-structured navigation system. SEO and metadata are well implemented, including Open Graph tags and multilingual support. Security posture is adequate with HTTPS enabled using TLS 1.3 and 1.2, SPF and DMARC DNS records configured, and no critical vulnerabilities detected. However, improvements are needed such as enabling HSTS, fixing malformed CAA DNS records, enabling OCSP stapling, and improving certificate transparency compliance. Privacy compliance is strong with clear privacy and cookie policies and consent mechanisms in place, aligning with GDPR requirements. Overall, TUHH's website presents a professional, trustworthy, and user-friendly digital presence suitable for its educational mission. Strategic security enhancements and continuous monitoring are recommended to maintain and improve the security posture and user trust.

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.

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 technical university with a focus on engineering education and research. Its market position is that of a specialized, compact university in Hamburg with a clear research profile. The business model centers on delivering bachelor and master degree programs, fostering research and innovation, and facilitating technology transfer. The university targets students, academic staff, researchers, and international partners. Partnerships with technology institutes and innovation hubs strengthen its ecosystem. The website content and partner listings indicate active engagement in collaborative research and international exchange. The presence of career services and alumni networks suggests a comprehensive approach to student lifecycle management and community building. The university's certifications and funding acknowledgments reflect strong institutional credibility and public support.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and modern TLS protocols supported. DNS security practices include SPF and DMARC records, although DNSSEC is not enabled. The absence of HSTS and OCSP stapling reduces protection against certain attack vectors. Malformed CAA records indicate a configuration oversight that should be corrected. No critical vulnerabilities such as Heartbleed or FREAK were detected. Privacy policies and cookie consent mechanisms are implemented, supporting GDPR compliance. However, no explicit incident response or security policy documentation was found on the site. Overall, the security posture is adequate but could be strengthened by implementing recommended best practices and improving DNS and certificate configurations.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS and protect against protocol downgrade attacks.
  2. Correct the malformed CAA DNS records to valid entries to control certificate issuance and enhance domain security.
  3. Enable OCSP stapling on the web server to improve certificate revocation checking and reduce latency.
  4. Improve certificate transparency compliance by ensuring certificates are logged in public CT logs.
  5. Publish explicit security policies and incident response information to enhance transparency and preparedness.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and widely used content management system, indicating a stable and scalable platform. The frontend uses modern JavaScript and CSS assets with lazy loading and responsive design, contributing to good user experience and accessibility. Performance is moderate with a page load time of approximately 3.8 seconds and 69 resources loaded. SEO is supported by comprehensive meta tags, Open Graph data, and multilingual support. DNS configuration includes multiple authoritative nameservers and mail exchange servers, with SPF and DMARC records properly set. However, DNSSEC is not enabled, and CAA records are malformed. SSL configuration supports TLS 1.3 and 1.2 but lacks HSTS and OCSP stapling. No vulnerable cipher suites or known SSL vulnerabilities were detected. Overall, the technical infrastructure is solid but can benefit from security and performance optimizations.
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.
