Merck KGaA, Darmstadt, Germany · Healthcare · Germany
Medium risk. 2 critical or high findings in SSL/TLS and GDPR outside view.
Merck KGaA, Darmstadt, Germany operates as a leading global science and technology company with core business sectors in healthcare, life science, and electronics. The website reflects a mature enterprise with a strong global presence, targeting scientific and business audiences worldwide. The company offers a broad range of products and services, emphasizing innovation and accessibility. Technically, the website is built on Adobe Experience Manager, leveraging modern JavaScript libraries and analytics tools such as Google Analytics and Adobe DTM. The site demonstrates good performance, mobile optimization, and excellent accessibility features, including an embedded accessibility tool supporting various user needs. From a security perspective, the site enforces HTTPS and includes cookie consent mechanisms aligned with GDPR. However, it lacks some advanced security headers and does not publicly disclose a security policy or incident response contacts. The absence of WHOIS registration data is a concern but does not detract significantly from the site's legitimacy given the professional presentation and compliance indicators. Overall, the website is trustworthy, professionally maintained, and compliant with privacy regulations. Strategic improvements could focus on enhancing security transparency and WHOIS data availability to further bolster trust.
Scanned
NIS2 Art. 21(2)
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.
2 findings rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Could not establish secure connection to retrieve certificate information
What to do: Check if the server is accessible and SSL/TLS is properly configured
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires explicit consent for non-essential cookies
What to do: Implement a cookie consent banner that appears on first visit

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
