Risk levelMedium

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

Technische Universität Braunschweig is a well-established German technical university offering a wide range of educational and research services primarily in engineering and natural sciences. The website serves students, researchers, and academic staff with comprehensive information about study programs, research projects, and international cooperation. The university maintains a professional online presence with consistent branding and a clear navigation structure. Technically, the site is built on TYPO3 CMS with modern JavaScript libraries and uses Matomo analytics configured to disable cookies, reflecting a privacy-conscious approach. Security posture is moderate with HTTPS enforced but lacks visible security headers and formal vulnerability disclosure mechanisms. Privacy compliance is limited due to absence of explicit privacy and cookie policies in the accessible content. Overall, the site is trustworthy and professionally maintained but could improve transparency and security practices.

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

The university operates in the education sector with a public service business model focused on higher education and research. It targets students, academic staff, and international researchers. The website reflects a large institution with multiple faculties and international partnerships. The presence of multiple official subdomains and social media channels indicates a mature digital ecosystem. The lack of explicit business registration or VAT information is typical for public universities. The site supports various academic and administrative services, including login portals and career services, indicating a comprehensive service offering.

Security posture

The website enforces HTTPS and uses privacy-respecting analytics (Matomo with cookies disabled). However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. The login form uses POST method but no explicit CSRF tokens or advanced security measures are visible in the provided content. Overall, the security posture is adequate for a public university website but could be enhanced to meet higher security standards and compliance requirements.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide explicit contact information for security incidents, such as a dedicated security or abuse email address.
  5. Enhance accessibility features and conduct regular audits to improve user experience for all visitors.

Technical notes

Notes

The website is built on TYPO3 CMS with the Higher Education Package, a common choice for academic institutions. It uses jQuery 3.6.4 and asynchronous loading of scripts for performance optimization. Matomo analytics is integrated with cookie usage disabled, reflecting privacy awareness. The site is mobile optimized with responsive design and uses modern meta tags for SEO. Performance is moderate, with compressed CSS and JS assets. No hosting provider information is directly available. The site structure is complex with multi-level navigation supporting a large content base. Technical debt appears low, but security enhancements and privacy transparency are areas for improvement.
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.
