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

SportovniAukce.cz is an online auction platform specializing in original worn hockey jerseys and other collectible sports artifacts, primarily targeting sports fans and memorabilia collectors in the Czech Republic. The business operates under eSports.cz, s.r.o., a small-sized company founded in 2014, offering a niche marketplace with direct cooperation with sports clubs. The website provides a professional and user-friendly interface with clear auction rules, privacy policies, and cookie consent mechanisms, supporting a trustworthy user experience. Technically, the site leverages modern JavaScript libraries and frameworks such as jQuery, Nette Framework, and integrates Google Analytics and advertising services, ensuring moderate performance and good mobile optimization. However, the absence of WHOIS data and lack of visible security headers indicate areas for improvement in domain transparency and security posture. Overall, the platform demonstrates a solid business model with a focus on compliance and user engagement but would benefit from enhanced security practices and domain registration clarity.

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

9 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

    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 Strict-Transport-Security header

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 company holds a niche market position in the Czech Republic for sports memorabilia auctions, focusing on hockey-related collectibles. Its business model revolves around user registration and bidding on authentic sports items, often with certificates of authenticity. Revenue streams likely include auction fees and advertising. The platform's partnership ecosystem includes direct cooperation with sports clubs and advertising partners like Google and TOPlist. Growth indicators include a steady auction schedule and charity auction events. Strategic observations suggest opportunities in expanding security policies, improving domain registration transparency, and enhancing accessibility to strengthen market trust and compliance.

Security posture

The website exhibits a moderate security maturity level with HTTPS usage and cookie consent compliance. However, the lack of detected HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces its defense-in-depth posture. No explicit incident response or vulnerability disclosure policies are present, which could hinder rapid response to security events. The site does not expose sensitive data visibly and uses secure forms, but updating third-party libraries and implementing stronger security headers are recommended. Compliance with GDPR is evident through detailed privacy policies and user data handling disclosures. Overall, the security posture is adequate but requires enhancements to meet higher standards.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a formal vulnerability disclosure and incident response policy to improve transparency and readiness.
  3. Regularly update and audit third-party libraries to mitigate vulnerabilities.
  4. Enhance accessibility features to comply with WCAG standards for broader user inclusivity.
  5. Clarify domain registration details or use verified WHOIS data to improve trustworthiness.

Key observations

  1. Website is fully accessible with no blocking or WAF challenges.
  2. WHOIS data is unavailable, which is unusual and reduces domain trust.
  3. Site uses modern JavaScript libraries and frameworks with good cookie consent implementation.
  4. Business information is clearly presented with contact emails and privacy policy.
  5. Advertising is primarily via Google AdSense with proper cookie consent.
  6. No security headers detected in provided data; security posture could be improved.
  7. Content is focused on sports memorabilia auctions, safe for general audiences.
Technical notes

Notes

The website uses a combination of jQuery, Nette Framework, and third-party libraries such as LightGallery for UI enhancements. Google Analytics and Google Ads are integrated for tracking and monetization. The site is mobile responsive with good navigation and content structure. Performance is moderate, with asynchronous loading of scripts and images. However, the absence of visible security headers and incomplete WHOIS data indicate technical debt in security and domain management. There is no detected CMS, suggesting a custom or framework-based solution. Opportunities exist to improve SEO, accessibility, and security configurations to reduce risks and enhance user experience.
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.
