Medium risk. 6 critical or high findings in Security headers, GDPR outside view and 1 other check.
EOSclub.app is a well-established SaaS platform specializing in sports club and association management. It offers a comprehensive suite of tools including member database management, payment processing linked to e-banking, communication channels, attendance tracking, match nominations, GDPR-compliant registration, document sharing, and mobile applications for iOS and Android. The platform targets a broad range of sports clubs, from small to large organizations, and boasts over 222,000 active members and 980+ clubs across 71 sports, positioning itself as a significant player in the sports management software market. Technically, the website employs modern JavaScript frameworks such as Alpine.js and Swiper.js, integrates analytics tools like Google Tag Manager and Hotjar, and uses a custom CMS hosted on eoscz.eoscms.zone. The site is well-optimized for mobile devices, features fast loading times, and demonstrates good SEO and accessibility practices. The presence of cookie consent mechanisms indicates attention to privacy compliance, although explicit privacy and terms of service documents are not found. From a security perspective, the site enforces HTTPS with strong SSL configuration and includes standard security headers. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms suggests areas for improvement in security transparency and readiness. Overall, EOSclub.app presents a professional, trustworthy, and technically mature platform with strong business credibility. To enhance its security posture and privacy compliance, it should publish clear privacy policies, terms of service, and security incident contacts. These steps will further solidify trust and compliance with regulatory standards.
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.

What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions
SSL certificate uses 256-bit key, which is considered weak

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.
