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

9 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      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';…

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

TUKE operates in the education sector, targeting students, researchers, and academic partners. Its business model centers on providing accredited study programs and conducting research. The university benefits from a large alumni base and international partnerships, enhancing its competitive advantage. Revenue streams likely include tuition, government funding, and research grants. The partnership ecosystem includes Erasmus+ and Ulysseus European University, indicating strategic collaborations. Growth indicators include recent infrastructure projects like the Slovak supercomputer and advanced 5G campus network. The website content and structure support clear communication of academic offerings and events, reinforcing its market presence.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and no exposed sensitive data. The cookie consent banner indicates awareness of privacy regulations. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerable libraries or insecure forms were detected. Compliance with GDPR is evident through privacy policy and consent mechanisms. Overall, the security maturity is good but could be enhanced by formalizing policies and incident response information.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and frameworks.
  2. Add an incident response contact email (e.g., security@ or abuse@) to improve transparency.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Provide clear terms of service to cover legal aspects of website and service use.
  5. Regularly review and update third-party scripts and dependencies to mitigate vulnerabilities.

The website is built on a modern React and Next.js framework, ensuring fast performance and good SEO optimization. It uses SVG images and responsive design techniques for excellent mobile compatibility. The technical infrastructure appears robust with no broken elements or errors detected.

Overall, the technical implementation supports a high-quality user experience with minimal technical debt.
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.
