Security report for medimerck.cz

Healthcare · Czech Republic

Low risk. 3 critical or high findings in Security headers and SSL/TLS.

Security score

76/100

Risk levelLow

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

The website www.medimerck.cz appears to be a healthcare portal targeting patients and doctors in the Czech Republic. It is built on Adobe Experience Manager CMS and uses common web technologies such as jQuery, Adobe Launch for tag management, and OneTrust for cookie consent. The site content is accessible without any WAF or security blocking mechanisms. However, the WHOIS data for the domain is unavailable, which raises concerns about domain registration transparency and trustworthiness. The website lacks explicit privacy policies, contact information, and security policies, which are important for compliance and user trust in healthcare-related services. The technical infrastructure is moderately modern but could benefit from enhanced security headers and clearer business information.

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

3 findings rated critical or high. Fix these first.

  1. 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
      • OWASP A04:2025
      • ASVS V3.4.1

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 behind the website seems to operate in the healthcare sector, providing a portal for patients and doctors. The site is likely small in scale and focused on the Czech market. There is no clear information about the business model, parent company, or subsidiaries. The lack of visible contact details and privacy policies limits the ability to fully assess business credibility. The use of Adobe Experience Manager suggests a professional approach to content management, but the placeholder meta description indicates incomplete content optimization. The site integrates marketing tools like ShareThis but does not show evidence of extensive advertising or affiliate programs.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism via OneTrust, indicating some attention to privacy compliance. However, no explicit security headers were detected in the provided content, and there is no published security or incident response policy. The absence of WHOIS registrant data reduces trust in domain legitimacy. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is moderate but could be improved by publishing security policies, adding security headers, and providing clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy and make it easily accessible on the website.
  2. Add explicit security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  3. Provide clear and verified contact information including emails and phone numbers for business and security inquiries.
  4. Implement and publish a vulnerability disclosure or security.txt file to enhance transparency.
  5. Obtain and display relevant business certifications and security compliance badges to improve trust.

Technical notes

Notes

The website uses Adobe Experience Manager CMS, jQuery, jQuery UI, Adobe Launch for tag management, and OneTrust for cookie consent. The site loads asynchronously loaded scripts and stylesheets, indicating a modern approach to performance. Mobile optimization and accessibility appear good based on meta viewport and accessibility tool integration. SEO optimization is basic with placeholder meta description and limited structured data. Hosting provider and SSL configuration details are not explicitly available. The site could improve performance by optimizing resource loading and enhancing SEO metadata.
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.
