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, supplements, cosmetics, and health-related products. The website targets the general Czech population and positions itself as the first online pharmacy in the Czech Republic with a comprehensive product offering and health advice. The business model is e-commerce retail focused on healthcare products, supported by a strong digital presence and marketing efforts. Technically, the website employs modern web technologies including Alpine.js for interactivity, Google Tag Manager for analytics and marketing integration, and Microsoft Clarity for user behavior tracking. The site is well optimized for performance, mobile responsiveness, and SEO, providing an excellent user experience with clear navigation and professional design. From a security perspective, the site enforces HTTPS, uses cookie consent mechanisms compliant with GDPR, and implements best practices such as async script loading and no visible sensitive data exposure. However, the absence of WHOIS data and lack of explicit security and incident response policies reduce the overall trustworthiness. No critical vulnerabilities were detected in the content or scripts. Overall, Lékárna.cz presents a professional and trustworthy online pharmacy platform with strong business credibility and technical maturity. Strategic improvements in transparency around security policies and domain registration would further enhance trust and compliance.

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

Lékárna.cz holds a strong market position as the first and one of the largest online pharmacies in the Czech Republic. Its competitive advantage lies in a broad product portfolio covering medicines, supplements, cosmetics, and health foods, combined with expert health advice and a user-friendly e-commerce platform. Revenue streams are primarily from direct online sales, supported by affiliate marketing and advertising partnerships. The target customers include health-conscious individuals, parents, and pet owners. The company leverages partnerships such as mojalekaren.sk for regional expansion. Growth indicators include extensive marketing integrations and a comprehensive cookie consent system indicating mature data practices.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement, cookie consent aligned with GDPR, and use of reputable analytics and marketing tools. Security headers are partially present but could be enhanced with additional headers like HSTS and X-Frame-Options. No exposed sensitive data or vulnerable libraries were identified. The lack of published security policies, incident response plans, and vulnerability disclosure mechanisms represents a compliance gap. The WHOIS data absence is a concern for domain legitimacy verification. Overall, the security maturity is good but can be improved by adding transparency and formal security documentation.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  3. Enhance HTTP security headers by adding HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Verify and update WHOIS domain registration information to ensure domain legitimacy and compliance.
  5. Provide contact information for a Data Protection Officer or privacy contact to strengthen GDPR compliance.

Technical notes

Notes

The website uses a modern and performant technology stack including Alpine.js for frontend interactivity and Google Tag Manager for analytics and marketing integration. The site is optimized for fast loading and mobile responsiveness, with proper use of DNS prefetch and preconnect to improve performance. SEO is well addressed with meta tags, Open Graph data, and structured JSON-LD data. Accessibility is good with semantic HTML and ARIA attributes. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Technical risks are minimal but monitoring third-party scripts for vulnerabilities is recommended.
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.
