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

3 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 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. 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

The university operates in the education sector, serving students, researchers, and academic staff. Its business model is public and non-commercial, focusing on education, research, and societal benefit. The site highlights key services such as degree programs, research initiatives, career services, and international cooperation. The partnership with the Berlin University Alliance enhances its collaborative research capabilities. The digital presence supports recruitment, information dissemination, and community engagement. Growth indicators include active news, events, and thematic portals. The university maintains a strong brand with consistent messaging and social media engagement.

Security posture

The website demonstrates a solid security foundation with HTTPS and privacy-conscious analytics. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of common security headers like Content-Security-Policy and lack of published security policies or incident response contacts suggest room for improvement. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. The site respects Do Not Track and disables cookies in analytics, aligning with GDPR requirements. Overall, the security maturity is good but could be elevated with additional best practices and explicit policies.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response information page to improve transparency and preparedness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance visibility of contact information for security and privacy concerns to build user trust.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.

The website is powered by TYPO3 CMS, a robust open-source content management system widely used in academia. It uses Matomo for analytics with privacy features enabled, reflecting a commitment to user privacy. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data. Performance is moderate, with room for optimization in loading speed. The technical stack is modern and well-maintained, supporting a large and diverse user base. No hosting provider details were identified from the content. The site uses standard web technologies including HTML5, CSS, and JavaScript, with no deprecated or vulnerable libraries detected.
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.
