0–100, higher is better. How it is calculated

Česká unie sportu, z.s. is the largest umbrella and service sports organization in the Czech Republic, providing a broad range of services including operation of sports facilities, educational programs, and an information system for sports entities. The organization targets sports clubs, associations, athletes, and sports enthusiasts within the Czech Republic, positioning itself as a key player in the national sports ecosystem. The website reflects a professional and consistent brand image with clear navigation and relevant content. Technically, the site employs modern JavaScript libraries and responsive design, ensuring good user experience across devices. Security posture is adequate with HTTPS enforced and cookie consent implemented, though improvements are needed in security headers and explicit privacy policies. The absence of WHOIS data is a notable concern for domain legitimacy verification but does not detract significantly from the overall trustworthiness given the professional presentation and official registration details displayed. Strategic recommendations include enhancing security headers, publishing comprehensive privacy and terms policies, and verifying domain registration details to improve trust and 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.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

Each check with its score, findings and the evidence it collected.

How this score is calculated

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.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

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.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The organization operates as a non-profit entity focused on supporting and servicing the sports sector in the Czech Republic. Its business model revolves around managing sports facilities, providing education in sports management and wellness, and maintaining an information system for sports organizations. The presence of multiple institutional and media partners indicates a strong partnership ecosystem that supports its market position. The website content and linked domains suggest a well-established network within the sports community. Growth indicators include recent news updates and active social media engagement. Revenue streams likely include facility operations, educational services, and possibly membership or service fees. The organization's large size and official registration reinforce its importance in the national sports infrastructure.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a cookie consent mechanism in place, indicating awareness of privacy and security requirements. However, the lack of detected security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security suggests room for improvement in hardening the site against common web attacks. No exposed sensitive data or vulnerable libraries were identified, and forms appear to be basic with no advanced security features visible. The absence of a security policy or incident response contact information limits transparency and preparedness for security incidents. Compliance with GDPR is partially indicated by the cookie consent but lacks a comprehensive privacy policy. Overall, the security posture is functional but could benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web vulnerabilities.
  2. Publish a detailed privacy policy and terms of service pages to improve transparency and compliance with GDPR and other regulations.
  3. Establish and publicize a security policy and incident response contact channels to demonstrate readiness and accountability.
  4. Verify and update WHOIS domain registration information to improve legitimacy and trustworthiness.
  5. Enhance accessibility features to meet standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a combination of popular JavaScript libraries such as jQuery, Select2, Swiper, Owl Carousel, AOS, and Slidebars to deliver a dynamic and responsive user interface. The design is modern and mobile-optimized, with clear navigation menus and interactive elements like carousels and video popups. Performance is moderate, with no explicit indicators of slow loading but some reliance on external CDNs for fonts and scripts. The site does not appear to use a CMS or identifiable hosting provider from the data available. SEO optimization is basic, with meta tags present but no structured data like JSON-LD or Open Graph tags detected. Technical debt appears low, but opportunities exist to improve SEO, accessibility, and security configurations to reduce risks and enhance user engagement.
Standards and sources

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.
