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

MSD Ireland is a subsidiary of Merck & Co., Inc., a leading multinational pharmaceutical company. The website reflects a mature and professional digital presence focused on healthcare innovation, patient education, and corporate responsibility. The company operates in the pharmaceutical and animal health sectors, targeting patients, healthcare professionals, and employees. The website is well-structured, mobile-optimized, and uses modern technologies such as WordPress and Yoast SEO to enhance user experience and search engine visibility. Security practices are solid with HTTPS enforced and domain protections in place, although DNSSEC is not enabled. Privacy and cookie policies are comprehensive and GDPR compliant, with a clear cookie consent mechanism. No critical security vulnerabilities or suspicious content were detected, and the domain registration aligns well with the company's history and legitimacy.

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 Ireland holds a strong market position as part of a global pharmaceutical leader. The business model centers on research, development, and supply of medicines and vaccines, supported by corporate responsibility initiatives and employee engagement. The website's extensive network of related MSD domains and partner sites indicates a broad operational footprint. The company leverages digital tools for marketing, analytics, and user engagement while maintaining compliance with privacy regulations. The presence of gender pay reports and whistleblowing policies highlights a commitment to transparency and ethical practices.

Security posture

The website demonstrates a good security posture with HTTPS enabled and domain status flags preventing unauthorized domain changes. The absence of DNSSEC is a minor gap. No exposed sensitive data or vulnerable libraries were identified in the HTML content. However, the site lacks publicly available security policies or incident response contacts, which could enhance trust and preparedness. Cookie consent mechanisms are implemented, supporting privacy compliance. Overall, the security maturity is appropriate for a large enterprise in the healthcare sector but could be improved with additional transparency and DNS security enhancements.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Consider implementing a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by providing more detailed data retention and privacy practices.

Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO plugin, indicating a modern and SEO-friendly infrastructure. Hosting appears to be on Amazon AWS, providing reliable performance and scalability. The site uses Google Tag Manager for analytics and tracking, and cookie consent is managed via a recognized third-party service. The design is responsive and accessible, with good use of semantic HTML and ARIA roles. Performance is moderate, with opportunities for optimization in image loading and script management. No critical technical debt or outdated technologies were detected, suggesting a well-maintained platform.
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.
