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

Česká unie sportu operates an information system website providing public access to data about sports clubs and physical education units affiliated with district associations in the Czech Republic. The website serves as a resource for sports organizations and the general public interested in sports entities, offering search functionality and statistical data about registered sports units and individuals. The site is positioned as a national sports union information provider with a medium-sized organizational footprint and a focus on transparency and public information dissemination. Technically, the website employs standard web technologies including HTML5, CSS3, and JavaScript, with integrations such as Google Tag Manager for analytics and Google Maps API for location services. The site is mobile-optimized with a moderate performance profile and basic accessibility features. However, no CMS or advanced frameworks are detected, indicating a custom or lightweight implementation. From a security perspective, the website uses HTTPS and implements a cookie consent mechanism, reflecting basic compliance with privacy regulations. However, it lacks visible security headers and published privacy or security policies, which are areas for improvement. No critical vulnerabilities or blocking mechanisms were detected, indicating a stable but basic security posture. Overall, the website is functional and professional but would benefit from enhanced privacy disclosures, security policies, and contact information to improve trust and compliance. Strategic recommendations include publishing comprehensive privacy and terms of service documents, implementing security headers, and providing clear incident response contacts.

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

7 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

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 in the sports sector as a non-profit or membership-based entity providing informational services. Its market position is national within the Czech Republic, targeting sports clubs, associations, and the public. The business model centers on data provision and transparency rather than commercial transactions. Key services include maintaining a database of sports entities, enabling member searches, and publishing statistics. The website's partnership with the main ČUS site (cuscz.cz) indicates a close relationship within the sports union ecosystem. Growth indicators include a large database of registered individuals and clubs. The absence of commercial advertising or affiliate programs suggests a focus on service rather than revenue generation. The organization could leverage its data assets for expanded digital services or partnerships.

Security posture

The current security maturity level is basic. The use of HTTPS and cookie consent aligns with minimum privacy and security standards. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces protection against common web attacks. No explicit privacy policy or incident response information is provided, which is a compliance gap under GDPR and related regulations. The site does not expose sensitive data or show signs of vulnerabilities in the provided content. Incident response readiness appears minimal due to lack of published contacts. Overall, the security culture seems functional but could be significantly improved with formal policies and technical hardening.

Recommendations

  1. Publish a comprehensive privacy policy detailing data collection, usage, and user rights.
  2. Add terms of service and a security policy page to clarify user and organizational responsibilities.
  3. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information for security incidents, including dedicated email addresses.
  5. Conduct regular security audits and vulnerability assessments to identify and remediate risks.

Technical notes

Notes

The website uses a straightforward technology stack with HTML5, CSS3, and JavaScript, supplemented by Google Tag Manager and Google Maps API. The site is mobile responsive and has a moderate performance profile. There is no evidence of a CMS or advanced frameworks, suggesting a custom-built or lightweight platform. SEO optimization is basic with standard meta tags but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but present. Hosting details are not explicit, but DNS uses Czech name servers consistent with the organization's location. The site could benefit from modernization including enhanced SEO, accessibility improvements, and adoption of security best practices.
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.
