Český tenisový svaz · Other · Czech Republic
High risk. 10 critical or high findings in GDPR outside view, Security headers and 2 other checks.
Český tenisový svaz operates as the official national tennis federation of the Czech Republic, providing comprehensive services including player registration, tournament organization, rankings, and training for players, coaches, and referees. The website serves as a central hub for tennis-related information, official documents, and communication with the tennis community. It targets tennis players of all ages, clubs, and officials within the Czech Republic, positioning itself as the authoritative body in Czech tennis. Technically, the website uses a traditional tech stack with Bootstrap and jQuery, alongside Google Analytics for user tracking. While the site is functional and well-structured, it uses an outdated jQuery version which may expose it to security vulnerabilities. The site lacks visible cookie consent mechanisms and security headers, which are important for compliance and security best practices. From a security perspective, the site benefits from HTTPS and secure login forms but should update its JavaScript libraries and implement modern security headers. The WHOIS data confirms the domain's legitimacy and long-standing presence, reinforcing trust in the organization. Overall, the site is professional and trustworthy but could improve its security posture and privacy compliance. Recommendations include updating JavaScript libraries, implementing cookie consent banners, adding security headers, and enhancing privacy disclosures to align with GDPR requirements. These steps will improve user trust, security, and regulatory compliance.

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.

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.
