Deutsches Klimarechenzentrum GmbH · Energy · Germany
Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.
The Deutsches Klimarechenzentrum GmbH (DKRZ) operates as a national service center providing high-performance computing and data management infrastructure to support climate research in Germany. The website reflects a well-established organization focused on delivering computational resources, data storage, and expert services to the scientific community engaged in climate modeling and simulations. Their market position is strong within the German and international climate research ecosystem, emphasizing collaboration and advanced technological support. Technically, the website is built on the Plone CMS platform, leveraging Bootstrap for responsive design and Matomo for privacy-conscious analytics. The site demonstrates good mobile optimization, clear navigation, and professional content presentation. However, some improvements could be made in accessibility and the implementation of security headers. From a security perspective, the site enforces HTTPS and uses script integrity attributes, but lacks explicit security headers and a published security policy or incident response information. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is partially addressed with a comprehensive privacy policy but lacks a cookie consent mechanism. Overall, the website is trustworthy, professional, and serves its target audience effectively. Strategic enhancements in security headers, cookie consent, and incident response transparency would further strengthen its security posture and compliance.
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.

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.

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.
