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

Carl von Ossietzky Universität Oldenburg is a well-established public university in Germany, founded in 1973, offering a broad range of academic programs and research activities. The website serves as an information portal for students, researchers, staff, and international visitors, providing access to study programs, research news, events, and administrative resources. The university emphasizes research excellence, international cooperation, and lifelong learning. Technically, the site is built on TYPO3 CMS with modern frontend libraries and is served securely over HTTPS. The site is well-structured, mobile-optimized, and accessible, with good SEO practices. However, explicit privacy and cookie policies are not clearly presented, and no incident response or vulnerability disclosure information is available, which are areas for improvement. Overall, the site reflects a professional and trustworthy academic institution with a solid digital presence.

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

5 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';…

  3. 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 SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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, targeting students, academics, and international partners. It maintains a strong market position as a research-oriented institution with a comprehensive offering of degree programs and continuing education. The business model is public and non-commercial, focusing on education, research, and knowledge transfer. The website supports this model by providing detailed information and resources. Partnerships with other academic institutions and research networks are implied through content and linked domains. The university's branding is consistent and professional, reinforcing its credibility and reputation.

Security posture

The website demonstrates a good security posture with enforced HTTPS, use of security headers, and no visible exposure of sensitive data. The use of Matomo analytics indicates a preference for privacy-conscious tracking. However, the absence of explicit privacy policies, cookie consent mechanisms, and incident response contacts suggests gaps in compliance and readiness. Security headers could be enhanced with additional directives like Content-Security-Policy. No vulnerable libraries or security issues were detected in the provided content. Overall, the security maturity is solid but could benefit from formalized policies and disclosures.

Recommendations

  1. Publish a comprehensive privacy policy and make it easily accessible from all pages.
  2. Implement a clear cookie consent mechanism to comply with GDPR requirements.
  3. Add a security.txt file or a dedicated vulnerability disclosure page with contact information.
  4. Enhance HTTP security headers, including Content-Security-Policy and X-Content-Type-Options.
  5. Provide explicit incident response contact channels for security issues.

Technical notes

Notes

The website uses TYPO3 CMS, a robust and widely used content management system, combined with modern JavaScript libraries such as jQuery, Bootstrap, Flexslider, and Owl Carousel for UI components. The site is responsive and optimized for mobile devices, with good accessibility features like skip navigation links and ARIA attributes. Performance is moderate, with some preloading of fonts and compressed CSS/JS assets. The use of Matomo analytics reflects a privacy-aware approach. No deprecated or vulnerable technologies were detected. Hosting details are not explicit but DNS name servers indicate university-managed infrastructure.
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.
