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

The website prostascreening.cz represents a national prostate cancer screening program in the Czech Republic, operated by the Ústav zdravotnických informací a statistiky ČR (Institute of Health Information and Statistics of the Czech Republic). It provides comprehensive information about prostate cancer screening, targeted at Czech men and healthcare professionals, supported by official health institutions and EU funding. The site offers educational content, news updates, and links to related screening programs, positioning itself as a trusted public health resource. Technically, the website employs modern web technologies including the Foundation CSS framework and Matomo analytics for user tracking. It is mobile-optimized, accessible, and uses HTTPS with a cookie consent mechanism, reflecting a mature digital infrastructure. However, no CMS or hosting provider details are explicitly identified, and performance is moderate. From a security perspective, the site uses HTTPS and cookie consent but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data for the domain reduces trustworthiness, though the website’s content and external references to official Czech health entities support its legitimacy. Overall, the site is professionally designed, content-rich, and trustworthy for its intended audience. Strategic improvements include publishing security policies, adding security headers, and clarifying domain registration details to enhance 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

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 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

      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

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

Prostascreening.cz operates as a government-backed healthcare screening program focused on early detection of prostate cancer in Czech men. Its business model is non-commercial, funded by the EU and Czech health authorities, targeting public health outcomes rather than revenue. The program leverages partnerships with multiple Czech medical societies and institutions, enhancing its credibility and reach. The website serves both patients and healthcare providers with educational resources, appointment information, and epidemiological data. Its market position is strong within the national healthcare ecosystem, supported by official endorsements and integration with other screening programs. Growth indicators include regular updates, conferences, and expanding informational content. The partnership ecosystem includes national health institutes and professional medical societies, reinforcing its authoritative role.

Security posture

The website demonstrates a baseline security posture with HTTPS enforcement and cookie consent mechanisms, indicating awareness of privacy and security best practices. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No explicit security or incident response policies are published, and no security.txt or vulnerability disclosure information is available, limiting transparency and readiness for security incidents. The use of Matomo analytics suggests moderate user tracking with privacy considerations. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Overall, the security posture is adequate but could be significantly improved with additional controls and transparency.

Recommendations

  1. Implement standard security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit security policies and an incident response plan on the website to improve transparency and preparedness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Clarify domain registration details and ensure WHOIS data is publicly available to improve trust and legitimacy.
  5. Regularly audit third-party scripts and analytics tools to mitigate risks from external dependencies.

Technical notes

Notes

The website uses a modern front-end stack with Foundation CSS framework and JavaScript modules, ensuring responsive and accessible design. Matomo analytics is integrated for user behavior tracking with privacy controls. The site includes multimedia content via Vimeo iframes and uses SVG icons for UI elements. Performance is moderate, with no major issues detected but potential for optimization exists. No CMS or hosting provider information is evident, suggesting a custom or proprietary deployment. Accessibility features such as skip navigation links and ARIA roles are implemented, supporting usability for diverse users. SEO is supported by proper meta tags, Open Graph, and Twitter card metadata. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and performance tuning.
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.
