Risk levelMedium

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

Unilabs is the largest private provider of laboratory and diagnostic services in the Czech Republic, operating over 20 laboratories and 80 collection points with a workforce exceeding 1200 employees. The company offers a broad range of routine and specialized diagnostic tests including biochemistry, hematology, microbiology, immunology, pathology, genetics, and forensic genetics, also serving veterinary practices. The website reflects a professional and comprehensive digital presence with clear navigation, modern technology stack, and compliance with GDPR and cookie consent regulations. Security posture is strong with HTTPS and no visible vulnerabilities, though security headers and explicit security policies could be improved. The absence of WHOIS data reduces domain trust from a registration perspective but does not detract from the professional business presentation. Overall, Unilabs demonstrates a mature digital infrastructure supporting its market-leading position in healthcare diagnostics.

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

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

  2. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Unilabs holds a dominant market position in the Czech healthcare diagnostics sector, targeting healthcare professionals, hospitals, self-paying patients, and veterinary clinics. The business model centers on providing extensive laboratory testing services with a strong emphasis on quality and specialization. The company leverages partnerships, such as with SSG ČR, and maintains a global presence through its parent company. The website supports business growth through online appointment booking, e-shop for self-payers, and active social media engagement. The company’s strategic focus on innovation and customer-centric values is evident in its CARE BIG culture and service offerings.

Security posture

The website employs HTTPS with a valid SSL configuration and integrates cookie consent mechanisms, indicating good privacy compliance. Tracking and analytics tools include Google Analytics, Google Tag Manager, and Facebook Pixel, managed with user consent. However, the site lacks several recommended security headers (e.g., Content-Security-Policy, X-Frame-Options) and does not publish explicit security or incident response policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data is a concern for domain legitimacy but does not directly impact website security. Overall, the security posture is solid but could be enhanced with additional headers and transparency.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  3. Publish explicit security policy and incident response information to demonstrate security maturity and readiness.
  4. Investigate and resolve the missing WHOIS data to improve domain registration transparency and trustworthiness.
  5. Continue monitoring and updating privacy compliance measures, especially regarding data retention and user consent management.

Technical notes

Notes

The website is built using React, leveraging modern JavaScript frameworks and asynchronous loading of analytics and tracking scripts. It uses Cookiebot for cookie consent management and integrates Google Analytics, Google Tag Manager, and Facebook Pixel for user behavior tracking. The site is mobile-optimized with responsive design and good SEO practices including meta keywords and descriptions. Performance is moderate with deferred script loading. No CMS was explicitly detected. Hosting provider details are not available from the provided data. Accessibility features are basic but present. Overall, the technical infrastructure supports a professional and user-friendly experience with room for enhancement in security headers and accessibility.
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.
