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

Best4Run is a Czech Republic based specialty retailer focused on running shoes, apparel, and equipment. Established in 2015, it operates both an e-commerce platform and a physical store in Přerov, serving customers from surrounding regions. The website offers a comprehensive product catalog, educational content, and diagnostic services for runners. Technically, the site is built on the Shoptet e-commerce platform, leveraging modern web technologies and multiple analytics and marketing tools with user consent mechanisms. Security posture is good with HTTPS and CSRF protections, though some security headers could be improved. The absence of WHOIS data reduces domain trust but the website content and business presence appear professional and legitimate. Overall, the site is well-structured, user-friendly, and compliant with privacy regulations.

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Best4Run holds a strong market position as the largest running specialty store in Moravia, targeting running enthusiasts and athletes. Its business model combines online retail with physical store services, including gait diagnostics and consulting. The company leverages multiple brand partnerships and offers a wide range of products from shoes to nutrition. The presence of social login and marketing integrations indicates a mature digital marketing strategy. Growth potential is supported by educational content and community engagement through blogs and podcasts. However, the lack of visible corporate registration details and WHOIS transparency could be improved to enhance credibility.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS, CSRF tokens on login forms, and cookie consent management. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, which are recommended to mitigate common web attacks. No vulnerabilities or exposed sensitive data were found in the HTML content. Incident response and vulnerability disclosure policies are absent, which could be a compliance gap. Overall, the security posture is adequate for an e-commerce retailer but can be enhanced by implementing recommended headers and formal security policies.

Recommendations

  1. Implement and enforce security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Verify and publish domain WHOIS information to improve trust and legitimacy.
  3. Establish and publish incident response and vulnerability disclosure policies.
  4. Regularly update third-party libraries and monitor for vulnerabilities.
  5. Enhance accessibility features and conduct periodic security audits.

Technical notes

Notes

The website uses a mature e-commerce platform (Shoptet) with a tech stack including jQuery, Google Analytics, Facebook SDK, Microsoft Clarity, and various marketing tools. The site is mobile responsive with good SEO and accessibility basics. Performance is moderate, with multiple external scripts that could impact load times. The presence of consent management and structured data indicates good digital maturity. Opportunities exist to optimize performance by reducing third-party script load and improving security headers. The technical infrastructure supports business goals but should be continuously monitored for modernization and security improvements.
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.
