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

Univerzita Karlova is a prestigious and leading university in the Czech Republic, offering a wide range of academic programs, research opportunities, and community engagement. The website reflects a mature digital presence with comprehensive content targeting students, staff, alumni, and the public. The institution maintains a strong market position as the top-rated university in the country, supported by a long domain history and consistent branding. Technically, the website employs modern JavaScript libraries such as jQuery and bxSlider, integrates Matomo and Google Tag Manager for analytics, and uses cookie consent mechanisms to comply with privacy regulations. The site is mobile-optimized and provides a good user experience, although accessibility features could be enhanced. From a security perspective, the site uses HTTPS with good SSL configuration and enforces cookie consent. However, it lacks explicit security headers and does not publish an incident response or vulnerability disclosure page. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website is trustworthy, professionally maintained, and compliant with GDPR. The domain WHOIS data confirms legitimacy and long-standing operation. Strategic improvements in security headers and incident response transparency would further strengthen the security posture.

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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • 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

Univerzita Karlova operates as a public university in the education sector, serving a large audience including students, faculty, researchers, and alumni. Its business model focuses on education delivery, research, and community services. The university holds a strong market position as the best-rated university in the Czech Republic, supported by extensive academic offerings and multiple campuses. The website indicates active engagement with stakeholders through news, events, and social media. Partnerships with related academic and research institutions are evident. The institution demonstrates growth through new campus projects and strategic initiatives like 4EU+ alliance. Revenue streams likely include public funding, tuition, research grants, and donations.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, cookie consent, and no visible sensitive data leaks. Use of Matomo analytics with consent shows privacy awareness. However, the absence of security headers such as Content-Security-Policy and lack of a published incident response or vulnerability disclosure policy represent gaps. No signs of malware or phishing were found. The site does not expose vulnerable libraries or insecure forms. Overall, the security maturity is good but could be improved by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security.txt file or dedicated incident response page with contact information to improve vulnerability disclosure and incident handling.
  3. Enhance accessibility features to meet higher standards for users with disabilities.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Increase transparency on data retention policies and privacy practices to strengthen GDPR compliance.

Technical notes

Notes

The website uses a combination of jQuery, bxSlider, Bootstrap, and custom scripts for UI and interactivity. Analytics are handled via Matomo and Google Tag Manager with consent-based activation. The site is hosted under a Czech registrar with a long-established domain. Performance is moderate with room for optimization. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or proprietary solution. Technical debt appears low, but improvements in accessibility and security headers are recommended to modernize the infrastructure.
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.
