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

Lékárna.cz is a leading Czech online pharmacy operated by Pears Health Cyber, s.r.o., offering a wide range of medicines, vitamins, dietary supplements, cosmetics, and health-related products. The website targets the general public in the Czech Republic and provides a comprehensive e-commerce platform with a strong focus on user experience and accessibility. The company positions itself as the first online pharmacy in the Czech Republic with a broad product portfolio and health advisory services. Technically, the website employs modern JavaScript frameworks like Alpine.js, integrates Google Tag Manager, Google Analytics, and Microsoft Clarity for analytics and user behavior tracking, and uses structured data for SEO and business information. The site is well-optimized for mobile devices and demonstrates good performance and accessibility standards. Security-wise, the site enforces HTTPS, implements multiple security headers, and provides a cookie consent mechanism compliant with GDPR. However, the absence of WHOIS data for the domain reduces trust slightly and suggests the need for further verification of domain registration details. Overall, the website is professional, secure, and compliant, with minor areas for improvement in transparency and incident response readiness.

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. 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, YouTube, Google Ads

      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 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';…
  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

The business operates in the healthcare and e-commerce sectors, focusing on retail pharmacy products online. It leverages partnerships with related domains such as mojalekaren.sk for the Slovak market and heureka.cz for joint data sharing. The business model is direct-to-consumer e-commerce with additional advisory content and loyalty programs. The company appears large with a consistent brand presence and high-quality content. Revenue streams likely include product sales, affiliate marketing, and advertising. The target customer segment is broad, including families, individuals seeking health products, and pet owners. The company uses advanced analytics and marketing tools to optimize customer engagement and retention. Strategic observations include strong market positioning in the Czech Republic and opportunities to enhance security transparency and incident response capabilities.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, comprehensive security headers, and GDPR-compliant cookie consent mechanisms. Tracking and marketing scripts are loaded conditionally based on user consent, reflecting good privacy practices. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a publicly available security policy or incident response contact information is a gap. The absence of a vulnerability disclosure policy or security.txt file limits transparency for security researchers. Overall, the site is secure but could improve by publishing formal security and incident response documentation and enhancing accessibility features.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet or exceed WCAG standards for broader user inclusivity.

Technical notes

Notes

The website uses a modern tech stack including Alpine.js for reactive UI components, Google Tag Manager for tag management, and Microsoft Clarity for user behavior analytics. The site is well-structured with responsive CSS and optimized for mobile devices. Performance appears fast with preconnect and dns-prefetch hints for critical external domains. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data describing the organization. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML. The site uses advanced consent management scripts to comply with GDPR. Technical risks are minimal, but reliance on multiple third-party scripts requires ongoing monitoring for vulnerabilities.
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.
