MSD Czech Republic operates as a leading branch of the global biopharmaceutical company Merck & Co., focusing on innovative drug research, clinical trials, and healthcare solutions. The website reflects a mature digital presence with comprehensive content tailored to healthcare professionals, patients, and job seekers. Technically, the site is built on WordPress with modern SEO and accessibility features, supported by Google Tag Manager and OneTrust for privacy 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

3 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.

    • 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

  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

MSD Czech Republic holds a strong market position as a key pharmaceutical player in the Czech healthcare sector, leveraging its global parent company's resources. The business model centers on pharmaceutical R&D, clinical research, and distribution of innovative medicines. The website supports recruitment, product information, and corporate communications, indicating a well-rounded approach to stakeholder engagement. Partnerships and related domains include MSD global sites and specialized portals for healthcare professionals. The company demonstrates commitment to compliance and transparency, evidenced by detailed privacy and cookie policies and certifications like Top Employer 2024.

Security posture

The website exhibits a good security maturity level with enforced HTTPS, cookie consent, and controlled use of third-party scripts. No critical vulnerabilities or exposed sensitive data were detected. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident and should be implemented to enhance protection against common web attacks. Incident response and vulnerability disclosure information are not publicly available, representing an area for improvement. Overall, the security posture aligns with industry expectations for a large healthcare organization but could benefit from additional transparency and technical hardening.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security policy or security.txt file to facilitate vulnerability reporting and incident response.
  3. Regularly audit and update third-party scripts to mitigate supply chain risks.
  4. Enhance monitoring and validation of form inputs to prevent injection attacks.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses WordPress CMS with Yoast SEO for optimization, Tiny Slider for UI components, and Google Tag Manager for analytics management. The site is mobile responsive and includes accessibility features such as skip links and ARIA attributes. Performance is moderate, with room for improvement in loading speed and resource optimization. The hosting provider is not explicitly identified. The technical stack is modern and well-maintained, supporting a professional user experience. Opportunities exist to improve security headers and streamline third-party dependencies to reduce technical debt.
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.
