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

7 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

    • 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 Strict-Transport-Security header

      Forces HTTPS connections

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

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 as a large educational entity within the Czech Republic's higher education sector. Its business model revolves around delivering academic programs, conducting research, and fostering international academic exchanges. The website reflects a mature digital presence with consistent branding, multiple faculties and institutes linked, and a broad partnership ecosystem. The institution leverages various subdomains and partner sites for specialized services, indicating a well-established organizational structure. Certifications like the HR Award and GDPR compliance reinforce its credibility and commitment to quality standards.

Security posture

The website employs HTTPS with an excellent SSL configuration and integrates a cookie consent mechanism aligned with GDPR requirements. Usage of Matomo analytics suggests a privacy-conscious approach. However, the absence of explicit HTTP security headers (e.g., CSP, HSTS) in the HTML source is a notable gap. No visible vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or incident response contact limits transparency in security governance. Overall, the security posture is solid but could be enhanced by implementing recommended headers and formal security disclosures.

Recommendations

  1. Implement standard HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and trust.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure and communication with security researchers.
  4. Regularly audit and update third-party libraries and frameworks to mitigate risks from outdated components.
  5. Enhance monitoring and logging capabilities to detect and respond to potential security incidents promptly.

Technical notes

Notes

The website is built on the WebCore 2.1 CMS platform and utilizes a modern technology stack including jQuery, Modernizr, Swiper.js, jBox, Bootstrap 4.3.1, and Nette framework components. Lazy loading is implemented via Layzr.js, and the mobile menu uses Pushy.js, indicating attention to performance and mobile usability. The site demonstrates good SEO practices with proper meta tags and Open Graph data. Performance is moderate with room for optimization. Accessibility features are present, contributing to a good user experience. The technical infrastructure supports a professional and functional digital presence suitable for a large educational institution.
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.
