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

SYNLAB e-shop is an online platform offering a wide range of laboratory diagnostic tests for self-paying customers, operated by SYNLAB, a leading European provider of laboratory diagnostics. The website targets individual consumers seeking convenient access to health testing services. The platform is built on the Shoptet e-commerce system and integrates multiple analytics and marketing tools with a strong emphasis on user privacy and GDPR compliance. The site features comprehensive product listings, clear navigation, and professional branding, supporting a positive user experience. Security posture is good with HTTPS and CSRF protections, though some security headers could be improved.

Overall, the website demonstrates a mature digital presence with good compliance and security practices.

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. 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

      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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319

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

SYNLAB e-shop holds a strong market position as part of the SYNLAB Group, offering direct-to-consumer laboratory testing services in the Czech Republic. The business model focuses on e-commerce sales of health-related diagnostic tests, including preventive packages and genetic testing. The platform supports customer engagement through loyalty programs and detailed product information. The use of multiple tracking and marketing tools indicates active digital marketing efforts. The absence of explicit security policies or incident response contacts suggests an area for improvement. The website's clear contact information and customer support channels enhance business credibility. The platform's integration with Shoptet and external analytics providers reflects a modern, scalable infrastructure.

Security posture

The website enforces HTTPS and uses CSRF tokens on forms, indicating good baseline security practices. Cookie consent mechanisms and privacy policies demonstrate GDPR awareness. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for enhancement to mitigate common web vulnerabilities. No vulnerabilities or exposed sensitive data were detected in the analysis. The lack of a public security policy or incident response information limits transparency. Overall, the security posture is solid but could benefit from additional header implementations and published security documentation.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to strengthen security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly update JavaScript libraries, especially jQuery, to the latest secure versions.
  4. Enhance data retention and privacy policy details to clarify analytics data handling.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses the Shoptet e-commerce platform with jQuery 1.11.3 and integrates Google Analytics, Google Tag Manager, Microsoft Clarity, and Facebook SDK for analytics and marketing. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with some room for optimization. The presence of CSRF tokens on forms indicates secure form handling. Hosting provider details are not explicit. The technical stack is modern enough for the business needs but could be improved by updating legacy libraries and enhancing security headers. The site structure and metadata are well implemented, supporting good search engine visibility.
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.
