Risk levelMedium

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

The website 'Žilní poradna - léčba křečových žil a metliček' is operated by S.A.B. Medical, s.r.o., a small healthcare entity based in the Czech Republic specializing in venous insufficiency and varicose vein treatments. The site provides medical information, patient guidance, and details about treatment options such as radiofrequency, laser, and surgical methods. It serves a targeted audience of patients and individuals seeking specialized vascular care. The business model appears to be informational and advisory, potentially supported by medical product distribution partnerships. Technically, the website is built on the Estranky.cz CMS platform and uses legacy JavaScript libraries like jQuery 1.12.4 and jQuery UI 1.12.1. It integrates Google Analytics and Facebook SDK for user tracking and marketing purposes. The site shows basic mobile optimization and accessibility features but lacks advanced SEO and modern performance optimizations. No explicit security headers were detected, and privacy and cookie policies are absent, indicating compliance gaps with GDPR and related regulations. From a security perspective, the site uses HTTPS for external scripts, but the SSL configuration and security headers are unknown or missing. The absence of privacy and cookie policies, outdated libraries, and missing WHOIS domain registration data reduce the overall security posture and trustworthiness. No critical vulnerabilities or adult content were detected, but improvements are needed to enhance compliance and security. Overall, the website is functional and provides relevant healthcare content but requires significant enhancements in privacy compliance, security best practices, and technical modernization to improve trust and user experience.

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

8 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 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

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

S.A.B. Medical, s.r.o. operates in a niche healthcare segment focusing on venous diseases and treatments in the Czech Republic. The company leverages its website to educate patients and promote treatment options, likely generating revenue through medical services or product distribution partnerships. The presence of related partner domains indicates a collaborative ecosystem in medical supplies and oncology. The business targets patients with venous insufficiency and related conditions, positioning itself as a specialized advisory and treatment resource. Growth indicators include active content updates and training for medical professionals. However, the lack of domain registration transparency and privacy compliance may impact credibility and market trust.

Security posture

The current security posture is moderate but with notable gaps. The website uses HTTPS for external resources but lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options. The use of outdated JavaScript libraries increases the risk of vulnerabilities. Absence of privacy and cookie policies indicates non-compliance with GDPR, which is critical for healthcare-related sites handling personal data. No incident response or security contact information is provided. The WHOIS data inconsistency raises concerns about domain legitimacy. Overall, the site requires urgent improvements in security headers, library updates, privacy compliance, and domain registration transparency to mitigate risks and enhance trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add essential security headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  3. Update JavaScript libraries to current stable versions to reduce vulnerability exposure.
  4. Verify and correct domain WHOIS registration details to improve legitimacy and trust.
  5. Enhance mobile responsiveness and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built on the Estranky.cz CMS platform using legacy JavaScript libraries (jQuery 1.12.4 and jQuery UI 1.12.1). It integrates Google Analytics and Facebook SDK for tracking and marketing. The site loads CSS and JS resources from both the Estranky CDN and external sources. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. The absence of security headers and outdated libraries indicate technical debt and potential security risks. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is functional but requires modernization and security hardening.
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.
