nu Datenautomaten GmbH · Other · Germany
Medium risk. 6 critical or high findings in Security headers, GDPR outside view and 1 other check.
nuLiga is a specialized platform operated by nu Datenautomaten GmbH, focused on providing automated internet-based network solutions for tennis associations and leagues primarily in Germany and Austria. The website serves as a portal for various regional tennis associations, offering both public and administrative access. The business targets tennis clubs and associations, providing league and club management services through a network of regional subdomains. The company has been established since 2003, indicating a mature presence in its niche market. Technically, the website uses basic HTML, CSS, and JavaScript without modern frameworks or CMS detected. The site performance and mobile optimization are basic, with no advanced SEO or accessibility features evident. The error page analyzed is minimalistic, with no forms or tracking scripts, and no evidence of advanced security headers or HTTPS enforcement from the provided data. From a security perspective, the site lacks visible security headers and privacy or cookie policies, which are important for GDPR compliance and user trust. No incident response or vulnerability disclosure information is provided. The domain registration data is consistent with the business claims, showing a legitimate and stable domain age. No WAF or blocking mechanisms were detected, allowing full content access. Overall, the website is functional but basic, with room for improvement in security posture, privacy compliance, and technical modernization. The risk level is moderate due to missing security best practices but no critical vulnerabilities were found in the analyzed content.
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.
