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

proLékaře.cz is a leading Czech medical information portal primarily serving healthcare professionals, especially doctors. Operated by MeDitorial s.r.o., it offers a comprehensive range of services including medical news, accredited online courses, congress calendars, podcasts, and medical journals. The website is well-branded and positioned as the largest information source for Czech medical professionals. Technically, the site uses modern JavaScript libraries and integrates Google Tag Manager and OneSignal for analytics and notifications. The site is mobile-optimized and provides a good user experience with clear navigation and professional content. Security posture is adequate with HTTPS enabled and secure forms, but lacks some security headers and published security policies. Privacy compliance is partial, with a cookie consent mechanism present but no visible privacy policy or terms of service on the homepage. WHOIS data is unavailable, which reduces domain transparency and trustworthiness, though the site content and business information appear legitimate. Overall, the site scores well on content quality and business credibility but should improve privacy and security disclosures.

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

6 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, Cloudflare, Google APIs

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

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

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 portal targets Czech healthcare professionals with a focus on medical education and information dissemination. Its business model revolves around providing accredited courses, up-to-date medical news, and event information, supported by partnerships with reputable organizations like the Czech Medical Chamber and Elsevier. The presence of numerous specialized medical topics and a broad content catalog indicates a mature content strategy. The company appears medium-sized with a strong market position in the Czech healthcare media sector. The partnership ecosystem includes academic publishers and healthcare institutes, enhancing credibility and reach. Growth potential lies in expanding digital education offerings and leveraging multimedia content such as podcasts and videos.

Security posture

The website employs HTTPS and secure form validation, which are positive security indicators. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No published security policy, incident response plan, or vulnerability disclosure program is evident, which limits transparency and preparedness. The lack of WHOIS data further complicates trust assessment. Overall, the security maturity is moderate but could be significantly improved by implementing standard security headers, publishing security policies, and establishing a vulnerability disclosure channel.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against web vulnerabilities.
  2. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Improve WHOIS transparency by ensuring domain registration data is publicly available or provide justification for privacy protection.
  5. Enhance security posture by documenting incident response procedures and providing clear security contact information.

Technical notes

Notes

The website uses a modern JavaScript stack with libraries such as jQuery, Headroom.js, Magnific Popup, and jQuery Validation. It integrates Google Tag Manager for analytics and OneSignal for push notifications. The site loads fonts from Google Fonts and uses a CDN for static assets. The HTML is well-structured with proper meta tags and JSON-LD structured data for SEO and rich snippets. Performance is moderate with lazy loading images and responsive design for mobile devices. No CMS is explicitly detected. Hosting provider details are not available from the content. The site could benefit from improved security headers and enhanced privacy disclosures to reduce technical risks.
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.
