Labtestonline.cz is a Czech healthcare informational website dedicated to educating patients and the general public about laboratory tests and related diseases. It is supported and guaranteed by reputable Czech clinical biochemistry and medical societies, positioning it as a trusted source in the Czech healthcare education sector. The site offers comprehensive information on laboratory tests, diseases, screening, and includes educational videos and news updates, targeting individuals seeking to understand medical testing and health conditions better. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, jQuery, and integrates third-party services such as Google Tag Manager and Smartlook for analytics and user behavior tracking. The site is mobile-optimized, accessible, and SEO-friendly, providing a professional user experience. Security-wise, the website enforces HTTPS, uses CSRF tokens in forms, and implements cookie consent mechanisms, although it lacks some advanced security headers and explicit security policies.

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.

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

Labtestonline.cz operates as an educational platform within the healthcare sector, focusing on laboratory diagnostics and disease information. Its market positioning is strengthened by endorsements from Czech medical societies, enhancing trust and authority. The business model centers on providing free, comprehensive medical information to patients and healthcare consumers, likely funded or supported by professional organizations. The target audience includes patients, healthcare professionals, and the general public interested in medical testing. The website's partnership ecosystem includes Czech clinical biochemistry and medical societies, which serve as guarantors of content quality. Growth indicators include regular news updates, educational videos, and active social media engagement. The platform's operations emphasize content quality, user education, and compliance with privacy regulations, positioning it well within the Czech healthcare information market.

Security posture

The website maintains a good security posture with mandatory HTTPS encryption and secure form handling via CSRF tokens. Cookie consent is properly managed through CookieHub, indicating GDPR compliance. However, the absence of certain security headers such as Content-Security-Policy and Strict-Transport-Security suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The lack of a published security policy or incident response information is a gap in transparency. Overall, the site demonstrates a mature security approach suitable for an informational healthcare platform but would benefit from enhanced header configurations and explicit security disclosures to further strengthen trust and resilience.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and user trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Consider adding a terms of service page to clarify user rights and responsibilities.
  5. Enhance contact information visibility by including verified company emails and phone numbers for support and inquiries.

Technical notes

Notes

The website is built on a modern technology stack utilizing HTML5, CSS3, and JavaScript with jQuery and Bootstrap framework elements. It integrates third-party analytics and tracking tools such as Google Tag Manager and Smartlook, and employs CookieHub for cookie consent management. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with multiple CSS files preloaded and asynchronous loading of scripts to improve load times. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not disclosed. The technical implementation supports a professional and user-friendly experience but could benefit from further optimization and security enhancements.
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.
