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

Chuchle Arena Praha, s.r.o. operates a historic and prominent horse racing and equestrian sports venue located in Prague, Czech Republic. The company offers a multifaceted business model including horse racing events, show jumping competitions, event space rental, accommodation services, and a riding academy. The website reflects a well-established business with a strong market position in the Czech equestrian and sports hospitality sector. The target audience includes horse sports enthusiasts, families, tourists, and event organizers. Technically, the website uses a combination of legacy and modern web technologies including jQuery, Google Tag Manager, Google Analytics, Matomo, and Google reCAPTCHA. The site is built on the IPO CMS platform and demonstrates good mobile optimization and SEO practices. However, some technical debt is noted with the use of older JavaScript libraries and missing security headers. From a security perspective, the site enforces HTTPS and implements user consent mechanisms for cookies and tracking, aligning with GDPR requirements. The absence of WHOIS data reduces domain trustworthiness, and the lack of security headers and outdated libraries present moderate security risks. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website is professional, content-rich, and compliant with privacy regulations, but improvements in security headers, updated libraries, and domain registration transparency are recommended to enhance trust and security posture.

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.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. Security headers

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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 · found on this site
  • 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

Chuchle Arena Praha holds a leading position in the Czech horse racing and equestrian sports market, leveraging its century-long history and multifunctional venue capabilities. The business model integrates event hosting, accommodation, equestrian training, and e-commerce, targeting a diverse customer base from sports fans to corporate event organizers. Partnerships with reputable companies enhance its ecosystem and brand credibility. The website content and partner listings indicate a stable medium-sized enterprise with growth potential in hospitality and sports sectors. The absence of detailed financial or founding year data limits deeper business intelligence insights.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS, cookie consent, and CAPTCHA protections. However, the lack of security headers such as Content-Security-Policy and HSTS, combined with the use of an outdated jQuery version, introduces potential vulnerabilities. The absence of published security policies or incident response contacts indicates room for improvement in transparency and preparedness. No immediate high-risk vulnerabilities were identified, but proactive security enhancements are advisable to mitigate risks and align with best practices.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen browser security.
  2. Update JavaScript libraries, especially jQuery, to the latest stable versions to reduce vulnerability exposure.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Verify and publish domain WHOIS information or ensure privacy protection is justified and transparent to users.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website is built on the IPO CMS platform with a tech stack including jQuery 3.0.0, jQuery UI, Google Tag Manager, Google Analytics, Matomo, and Google reCAPTCHA. The site is mobile responsive and SEO optimized with proper meta tags and structured navigation. Performance is moderate, with potential improvements by updating legacy libraries and optimizing scripts. Accessibility is basic but functional. Hosting provider details are not disclosed. The site uses multiple external domains for analytics, fonts, and partner links. Overall, the technical infrastructure supports the business needs but would benefit from modernization and enhanced security configurations.
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.
