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

uLékaře.cz, s.r.o. is a Czech healthcare service provider specializing in corporate health management and employee wellness. The company offers data-driven health services including online medical advice, appointment assistance, and preventive health calendars tailored for businesses. Established around 2018, it targets HR departments and employers aiming to improve workforce health and productivity. The website reflects a professional and consistent brand with strong trust indicators such as ISO 27001 certification and client testimonials. Technically, the site uses modern analytics and marketing tools, is mobile-optimized, and provides a rich user experience with multimedia content. Security posture is solid with HTTPS, data encryption, and access controls, though additional security headers and incident response disclosures could enhance it. Privacy compliance is well addressed with comprehensive policies and cookie consent mechanisms. The absence of WHOIS data reduces domain trust slightly but does not detract from the overall legitimacy based on content and certifications.

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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Cloudflare, Google APIs

      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 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 company occupies a niche in the healthcare sector focused on corporate clients, leveraging data analytics to provide health insights and services that improve employee well-being and reduce company costs. Its business model combines SaaS-like health management tools with consulting and educational services for HR. The presence of a community and references from notable companies indicates a growing ecosystem and market acceptance. Revenue streams likely include subscription or service fees from corporate clients. The company maintains active social media channels and uses multiple marketing and analytics platforms to support growth and customer engagement. The lack of WHOIS transparency is a minor concern but may be due to local registry policies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, data encryption, regular backups, and two-factor authentication for sensitive access. It undergoes external audits and GDPR training, reflecting a strong security culture. However, the absence of explicit security headers (e.g., CSP, HSTS) and no visible incident response or vulnerability disclosure policies are gaps that could be addressed. The use of multiple third-party analytics and marketing scripts requires ongoing vigilance to prevent supply chain risks. No vulnerabilities or exposed sensitive data were detected in the analysis.

Recommendations

  1. Implement and publish security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance browser security.
  2. Develop and publicly share an incident response and vulnerability disclosure policy to improve transparency and readiness.
  3. Consider creating and hosting a security.txt file to facilitate responsible vulnerability reporting.
  4. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.
  5. Enhance WHOIS transparency if possible to improve domain trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, TikTok Analytics, Microsoft Clarity, LinkedIn Insight, Gemius, Adobe DTM, jQuery, GSAP, Lottie Player, and Snap.svg for animations and tracking. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate with multimedia content but generally well-structured HTML and CSS. SEO is supported by proper meta tags and Open Graph data. Hosting provider and CMS are not explicitly identified. The site uses multiple external domains for analytics and marketing, which requires careful management to maintain privacy and security.
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.
