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

MizunoStore.cz is a specialized e-commerce retailer focused exclusively on Mizuno brand footwear and sports apparel, serving the Czech Republic market. It operates as part of the ZebraStores.cz group, offering a wide product range including running shoes, trail shoes, indoor sports shoes, sportswear, thermal underwear, and accessories. The website provides a seamless shopping experience with a centralized cart shared across multiple related e-shops, fast shipping from its own warehouse, and customer support via phone and email. The presence of a physical showroom and clear contact details enhance customer trust. Technically, the site is built on ASP.NET WebForms with a custom CMS platform managed by ZebraStores.cz. It integrates modern marketing and analytics tools such as Google Tag Manager, Facebook Pixel, and Heureka widgets. The site is mobile-optimized and demonstrates good SEO practices. Security is well implemented with HTTPS and secure login forms, though it lacks some advanced security headers and explicit cookie consent mechanisms. From a security and compliance perspective, the site shows no signs of blocking or WAF interference, and no vulnerabilities were detected in the content. However, the absence of a cookie consent banner and explicit privacy policy details indicates room for improvement in GDPR compliance. WHOIS data is unavailable, likely due to privacy protection, but the site’s legitimacy is supported by its authorized reseller status, physical presence, and professional presentation. Overall, MizunoStore.cz is a credible and professionally managed e-commerce platform with a solid business model and good technical infrastructure. Strategic improvements in privacy compliance and security headers would further enhance its trustworthiness and regulatory adherence.

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

10 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

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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 CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 · 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.

Business context

Business profile

MizunoStore.cz holds a strong niche position as an authorized Mizuno brand retailer in the Czech Republic, leveraging the ZebraStores.cz group infrastructure. Its competitive advantage lies in exclusive brand focus, centralized shopping cart across multiple related e-shops, and comprehensive product offerings for various sports disciplines. Revenue streams are primarily from direct online sales supported by loyalty programs and physical showroom sales. The target customer segment includes sports enthusiasts, runners, and team sports players seeking quality Mizuno products. The partnership ecosystem includes e-shop development by Bluesoft and marketing integrations with major ad and analytics platforms. The company demonstrates growth potential through multi-channel sales and brand specialization.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure login forms, and no visible exposure of sensitive data. The integration of live chat and third-party marketing scripts is standard but requires ongoing monitoring for vulnerabilities. The lack of security headers such as Content-Security-Policy and X-Frame-Options is a minor gap that could be exploited in certain attack scenarios. No incident response or security policy information is published, which limits transparency. GDPR compliance is partial due to missing cookie consent mechanisms. Overall, the site is secure for typical e-commerce operations but would benefit from enhanced security controls and documented policies.

Recommendations

  1. Implement comprehensive cookie consent banner and mechanism to ensure GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Regularly audit third-party scripts and marketing tools for vulnerabilities and privacy compliance.
  5. Enhance accessibility features and provide more detailed privacy policy content addressing data retention and user rights.

Technical notes

Notes

The website is built on a legacy ASP.NET WebForms platform customized by ZebraStores.cz, integrating modern JavaScript libraries such as jQuery and jQuery UI. It uses Google Tag Manager and Facebook Pixel for marketing and analytics, along with Heureka widgets for customer reviews and trust signals. The site is mobile-optimized with responsive design elements and good SEO metadata. Performance is moderate, likely influenced by the legacy framework and multiple external scripts. There is an opportunity to modernize the tech stack to improve speed and maintainability. Hosting details are not explicit but likely on Windows-based infrastructure. Overall, the technical implementation supports business needs but could be enhanced with modernization and improved security 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.
