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. 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 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';…
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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 positions itself as the leading yoyo retailer in the Czech Republic, leveraging its reputation through European champion leadership. The business model focuses on direct online sales complemented by educational content and community engagement through competitions. Revenue streams are primarily from product sales, with potential upselling via accessories and skill toys. The target customer segment includes hobbyists and competitive yoyo players. The website integrates multiple marketing and tracking tools, indicating active customer engagement strategies. Partnerships with payment providers and logistics are implied but not explicitly detailed. The company appears small but well-established since 2010, with consistent branding and a strong local market presence.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and domain registration includes clientTransferProhibited status, reducing domain hijacking risks. However, the absence of DNSSEC and security headers such as Content-Security-Policy and HSTS reduces defense-in-depth. No public vulnerability disclosure or incident response contacts are provided, which could hinder timely security issue reporting. The use of multiple plugins increases the attack surface, necessitating regular updates and monitoring. Privacy compliance is partially implemented with cookie consent but lacks a comprehensive privacy policy. Overall, the security posture is adequate for a small e-commerce site but should be enhanced to mitigate emerging threats and comply fully with GDPR and other regulations.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen browser security.
  3. Publish a comprehensive privacy policy page detailing data collection, usage, and user rights to improve GDPR compliance.
  4. Create and maintain a security.txt file to facilitate vulnerability reporting and incident response.
  5. Regularly audit and update all WordPress plugins and core to mitigate vulnerabilities and maintain platform security.

Technical notes

Notes

The website uses a mature WordPress environment with WooCommerce for e-commerce functionality and Elementor for page building, indicating a modern and flexible technical infrastructure. Integration of multi-currency support and various plugins for comments, shipping, and discounts shows a feature-rich platform. Performance is moderate, with preloader scripts and asynchronous loading of analytics and tracking scripts. Mobile optimization is good, supported by responsive design and mobile-specific menus. SEO is supported by proper meta tags and structured data, although no explicit JSON-LD schema was detected in the provided HTML snippet. The hosting provider is not explicitly identified, but the domain registrar is joker.com. Overall, the technical stack is solid but could benefit from enhanced security configurations and performance optimizations.
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.
