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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 19 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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 institution holds a strong market position as a reputable applied sciences university in Germany, supported by multiple certifications and partnerships. Its business model focuses on education and research services, targeting students, academic staff, and international partners. The website supports this with detailed program information, international exchange pathways, and active social media engagement. The presence of multiple campuses and specialized faculties indicates a medium-sized organization with a broad academic offering. Strategic partnerships with regional and national academic networks enhance its ecosystem.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie consent management. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for enhancement. There is no public security policy or incident response contact information, which could improve transparency and readiness. The use of Matomo analytics respects privacy better than many alternatives, aligning with GDPR principles.

Recommendations

  1. Implement Content-Security-Policy and X-Frame-Options headers to strengthen protection against XSS and clickjacking.
  2. Publish a dedicated security policy and incident response contact details to improve transparency and trust.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.
  5. Enhance mobile optimization further to ensure excellent performance across all devices.

Technical notes

Notes

The website is built on TYPO3 CMS, leveraging modern JavaScript libraries such as GSAP and Swiper for interactive UI elements. Cookie consent is managed via in2cookiemodal, and analytics are handled by Matomo, indicating a privacy-conscious approach. The site is well-structured with semantic HTML and accessibility features, including keyboard navigation aids and ARIA roles. Performance is moderate, with room for optimization. The site is mobile responsive and SEO optimized with proper meta tags and structured data (JSON-LD). Hosting details are not explicit but name servers indicate academic or regional hosting consistent with the institution's profile.
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.
