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

      Forces HTTPS connections

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

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 operates a focused e-commerce business model in the retail sector, specializing in running-related products. It leverages partnerships with major sports brands and maintains a multi-country presence with localized sites. The business benefits from a loyal customer base supported by ambassador and affiliate programs. Its revenue streams are primarily from online sales of footwear, apparel, and accessories. The website's navigation and content structure support a positive user experience, aiding customer retention and conversion. The integration of advanced marketing and analytics tools suggests a data-driven approach to customer engagement and growth. No parent or subsidiary companies were identified, indicating an independent operation. The company maintains consistent branding and trust signals, enhancing market position.

Security posture

The website exhibits a solid security posture with HTTPS enforced and no visible exposure of sensitive data. The use of consent mechanisms for cookies aligns with GDPR requirements. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No vulnerabilities or malware indicators were found in the analyzed content. The site lacks publicly available incident response or security policy documentation, which could enhance transparency and preparedness. Overall, the security maturity is good but could be elevated by adopting additional best practices and publishing security-related policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan accessible to users and partners to improve transparency and trust.
  3. Conduct regular audits of third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  4. Enhance accessibility features to meet higher standards and improve usability for all users.
  5. Maintain and update privacy and cookie consent mechanisms in line with evolving regulations and best practices.

Technical notes

Notes

The website uses a modern technology stack combining Bootstrap for responsive design, React for dynamic UI components, and jQuery for legacy support. It integrates multiple third-party services for analytics, marketing, and user experience enhancements, including Google Analytics, Facebook Pixel, Exponea, and Smartlook. The site is hosted likely by REG-ZONER, a Czech hosting provider, consistent with the domain's WHOIS data. Performance is moderate with room for optimization, particularly in script loading and resource management. SEO is well addressed with proper meta tags and Open Graph data. The site is mobile optimized and provides a good user experience with clear navigation and structured content. No CMS was explicitly detected, suggesting a custom or proprietary platform. Technical risks include dependency on multiple external scripts which require ongoing monitoring.
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.
