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

The Universität Bremen website serves as the official digital presence of a medium-sized German university with approximately 20,000 students. It offers a broad range of academic programs including bachelor, master, and legal state examinations, and is recognized as an Excellence University since 2012. The site targets students, researchers, international visitors, and partners, providing comprehensive information on study programs, research, and university services. Technically, the site is built on TYPO3 CMS, employs Matomo for privacy-conscious analytics, and demonstrates good mobile optimization and accessibility. Security posture is strong with HTTPS enforcement, security headers, and cookie consent mechanisms. No critical vulnerabilities or suspicious content were detected, and the domain registration aligns with the university's identity and history.

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

4 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 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

Universität Bremen holds a solid market position as a recognized Excellence University in Germany, focusing on education and research. Its business model is public sector education, serving a diverse audience including students, academics, and industry partners. The university leverages partnerships with research centers like MARUM and alliances such as the Northwest Alliance. The website reflects a mature digital presence with clear navigation, multilingual support, and comprehensive service offerings. Growth indicators include international programs and extensive continuing education. The absence of direct contact emails suggests a preference for controlled communication channels via forms.

Security posture

The website exhibits a mature security posture with enforced HTTPS, multiple security headers, and a robust cookie consent framework compliant with GDPR. Use of Matomo analytics ensures anonymized data collection, enhancing privacy. No exposed sensitive data or vulnerable libraries were identified. However, the site lacks explicit incident response contact information and a security.txt file, which are recommended best practices. Overall, the security measures align well with the university's public and academic nature, minimizing risk exposure.

Recommendations

  1. Publish explicit incident response and security contact information to improve transparency and readiness.
  2. Implement a security.txt file to facilitate responsible vulnerability disclosure.
  3. Regularly review and update third-party scripts and libraries to mitigate emerging vulnerabilities.
  4. Enhance contact information availability by including verified official emails and phone numbers where appropriate.
  5. Continue to monitor and improve accessibility and mobile optimization to maintain high user experience standards.

Technical notes

Notes

The website is powered by TYPO3 CMS, a well-established open-source content management system, ensuring flexibility and scalability. The technology stack includes modern web standards such as HTML5, CSS3, and JavaScript, with Matomo analytics integrated for privacy-respecting user tracking. Hosting appears to be managed by DFN or university infrastructure, indicated by the nameserver dns-2.dfn.de. Performance is moderate with good mobile responsiveness and accessibility features. The site employs a custom cookie consent solution with detailed cookie categorization and user controls. Opportunities exist to further modernize by adopting newer frontend frameworks or enhancing performance optimization.
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.
