69/100

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

Merck KGaA, Darmstadt, Germany operates a comprehensive corporate website showcasing its leadership in science and technology across Healthcare, Life Science, and Electronics sectors. The website targets a global audience including customers, partners, investors, and job seekers, providing detailed information about company strategy, products, research, and sustainability efforts. The digital infrastructure is built on Adobe Experience Manager CMS, leveraging Akamai CDN and modern JavaScript libraries, ensuring a professional and accessible user experience. However, performance metrics are not available, indicating potential monitoring gaps. Security posture is weakened by an invalid or missing SSL certificate and lack of TLS protocol support, which are critical issues that must be addressed to protect user data and maintain trust. Privacy compliance is strong, with clear privacy and cookie policies and consent mechanisms aligned with GDPR. The website maintains a high level of business credibility with consistent branding, structured data, and active social media presence. Strategic recommendations include immediate SSL certificate remediation, enabling modern TLS protocols, and enhancing security headers and incident response disclosures to improve overall security and 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

1 finding rated critical or high. Fix these first.

  1. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Merck is positioned as a leading global science and technology company with a diversified portfolio in Healthcare, Life Science, and Electronics. The company leverages innovation and partnerships to drive growth and impact. The website reflects a mature business model focused on B2B and B2C engagement, with dedicated sections for investors, careers, and research. The presence of multiple regional domains and country selectors indicates a broad international footprint. Marketing and analytics tools such as Google Analytics and Adobe DTM support data-driven decision making. The company emphasizes sustainability and ethical business practices, enhancing its competitive advantage and brand reputation.

Security posture

The website demonstrates partial adherence to security best practices with several important headers configured, including Content-Security-Policy and Strict-Transport-Security. However, the SSL certificate is invalid or missing, and no TLS protocols are enabled, representing critical vulnerabilities that expose users to potential interception and data compromise. OCSP stapling and session resumption are disabled, reducing performance and security. No dedicated security policy or incident response information is publicly available, which limits transparency and preparedness. The overall security maturity is low, requiring urgent remediation to meet industry standards and regulatory requirements.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS and secure communications.
  2. Enable TLS 1.2 or higher protocols and disable deprecated SSL/TLS versions.
  3. Configure HSTS with includeSubDomains and preload flags to enforce HTTPS.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Publish a clear security policy and incident response contact information to enhance transparency and trust.
Technical notes

Notes

The website is built on a robust technical foundation using Adobe Experience Manager CMS and served via Akamai CDN, ensuring scalability and global reach. The use of modern JavaScript libraries and Google Fonts contributes to a polished user interface. However, the absence of performance data and the invalid SSL configuration indicate areas for technical improvement. Accessibility and SEO optimizations are well implemented, with appropriate meta tags, structured data, and ARIA attributes. The site supports mobile devices effectively. Technical debt is minimal but the security misconfigurations pose operational risks that could impact user trust and compliance.
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.
