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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Jizerská 50 is positioned as a leading sports event organizer in Central Europe, focusing on cross-country skiing and running events. Its business model revolves around event management, sponsorship, and merchandise sales. The website reflects a well-established brand with a domain age of over 20 years, consistent with the event's history. The partnership ecosystem includes major energy, telecom, and media companies, enhancing credibility and reach. The site targets sports enthusiasts and community participants, leveraging social media and digital marketing tools effectively. Growth indicators include multi-language support and integration with international event series like Ski Classics. The business maintains a medium-sized operational scale with a focus on regional and international sports communities.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, cookie consent management, and use of Google reCAPTCHA for form protection. However, it lacks explicit public documentation of security policies, incident response procedures, or vulnerability disclosure mechanisms. Security headers are partially inferred but not explicitly confirmed. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site follows good privacy compliance practices with GDPR-aligned cookie consent but could improve transparency by publishing dedicated security and incident response information. Overall, the security posture is good but could benefit from enhanced documentation and proactive disclosure.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and trust.
  2. Implement and verify security headers such as X-Frame-Options and X-Content-Type-Options.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet higher compliance standards.
  5. Regularly audit third-party scripts and dependencies for security vulnerabilities.

Technical notes

Notes

The website uses a combination of jQuery, Nette PHP framework, and modern JavaScript libraries like Slick Carousel and FontAwesome for UI elements. It integrates Google Tag Manager for analytics and SmartEmailing for marketing automation. The site is served over HTTPS with a responsive design optimized for mobile devices. Performance is moderate with room for improvement in loading speed and accessibility. The CMS appears custom or Nette-based, supporting multi-language content. The technical infrastructure is stable and suitable for event promotion but could benefit from modernization in frontend frameworks and enhanced performance optimization.
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.
