Medium risk. 5 critical or high findings in GDPR outside view and Security headers.
DFN (Verein zur Förderung eines Deutschen Forschungsnetzes e. V.) is a German non-profit organization that operates and develops the scientific communication infrastructure across Germany, connecting universities, research institutions, and research-related companies at approximately 850 locations. The organization holds a leading position in providing dedicated network and communication services tailored for the scientific community. Their key offerings include the nationwide fiber optic network X-WiN, security and identity services, collaboration tools, and cloud services. The website is professionally designed, content-rich, and optimized for both desktop and mobile users, reflecting a mature digital presence. Technically, the website is built on WordPress 6.7.1 with modern plugins such as Yoast SEO and Contact Form 7, and uses Matomo for privacy-conscious analytics. The site employs HTTPS with DNSSEC enabled, indicating a strong commitment to security. However, explicit security headers and incident response contacts are not evident, and no cookie consent mechanism is implemented, which are areas for improvement. The security posture is solid with no visible vulnerabilities or exposed sensitive data. The WHOIS data is limited due to DENIC policies but shows consistent domain management and DNSSEC usage, supporting legitimacy. Social media presence on Mastodon and LinkedIn enhances trust and engagement. Overall, the site demonstrates a high level of professionalism, security, and compliance suitable for a scientific network provider. Strategic recommendations include implementing explicit security headers, adding a security.txt file for vulnerability disclosure, providing clear incident response contacts, and introducing a cookie consent mechanism to enhance privacy compliance and user 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.

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.

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.
