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

Česká zemědělská univerzita v Praze (ČZU) is a prominent public university specializing in agricultural sciences, environmental studies, and related research fields. The website serves as a comprehensive portal for students, researchers, partners, and the public, offering information on faculties, study programs, research projects, and international cooperation. The university holds a strong market position in the Czech Republic, recognized for sustainability and academic excellence. The site is well-branded and professionally maintained, reflecting the institution's stature. Technically, the website employs a modern technology stack including HTML5, CSS3, JavaScript libraries such as jQuery, Swiper, and Bootstrap, and is built on the WebCore CMS platform. It features responsive design, accessibility considerations, and SEO best practices. Analytics are handled via Matomo with user consent mechanisms in place, indicating a mature digital infrastructure. From a security perspective, the site enforces HTTPS and includes cookie consent banners aligned with GDPR requirements. However, explicit security headers are not detected, and no public security policy or incident response contacts are published. No vulnerabilities or suspicious content were found. The absence of WHOIS data is due to CZ.NIC privacy policies, which is typical for Czech domains and does not detract from the site's legitimacy. Overall, the website demonstrates a strong security posture, good privacy compliance, and high business credibility. Recommendations include enhancing security headers, publishing a security policy, and adding vulnerability disclosure information to further strengthen trust and compliance.

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

ČZU operates as a large educational institution focused on agricultural and environmental sciences, serving students, academics, and industry partners. Its business model centers on delivering university education, conducting research, and fostering international collaborations. The university's market position is reinforced by its sustainability rankings and comprehensive academic offerings. The website supports this ecosystem with clear navigation to faculties, study programs, and research activities. Partnerships with various academic and industry entities are evident through linked domains. The institution maintains a professional online presence with certifications like HR Award and IEP, signaling quality and compliance. Growth indicators include active event calendars and media engagement. The university's operations are transparent with accessible contact information and legal disclosures.

Security posture

The website exhibits a mature security posture with enforced HTTPS and a cookie consent mechanism compliant with GDPR. The use of Matomo analytics with explicit consent indicates privacy-aware tracking. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces the overall security hardening. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a published security policy or incident response contacts is a gap in transparency and readiness. The WHOIS privacy protection is standard for Czech domains and does not raise suspicion. Overall, the site is secure but could improve by implementing additional HTTP security headers and publishing security-related policies.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and HSTS to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and preparedness.
  3. Regularly update all JavaScript libraries and dependencies to their latest secure versions to mitigate vulnerabilities.
  4. Add a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting of security issues.
  5. Continue maintaining GDPR compliance and enhance user privacy controls for analytics and tracking.

Technical notes

Notes

The website is built on the WebCore 2.1 CMS platform and uses a combination of modern front-end technologies including HTML5, CSS3, JavaScript libraries such as jQuery 1.11.1, Swiper.js for carousels, jBox for UI components, and Bootstrap 4.3.1 for responsive design. The site includes accessibility features and SEO-optimized meta tags including Open Graph tags for social media integration. Performance is moderate with asynchronous loading of some scripts and lazy loading of images. The site is mobile optimized with a responsive layout and mobile-specific menus. The use of Matomo analytics indicates a preference for privacy-respecting tools. There is no indication of outdated or vulnerable technologies, but some libraries like jQuery 1.11.1 are older and could be updated. Overall, the technical infrastructure is solid with room for modernization in some areas.
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.
