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

The website www.intersport.cz is an e-commerce platform for INTERSPORT, a retailer specializing in sportswear and sporting goods primarily targeting the Czech market. The site features a professional design with good mobile optimization and clear navigation, supporting a positive user experience. However, the absence of WHOIS data and lack of visible privacy, cookie, or terms of service policies limit the assessment of compliance and trustworthiness. Technically, the site uses modern web technologies such as HTML5, CSS3, JavaScript, and icon fonts, but lacks visible security headers and explicit security best practices. The security posture is weak due to missing HTTPS verification and security headers, which should be addressed to improve user trust and data protection. Overall, the site appears legitimate and functional but requires improvements in security and compliance documentation to enhance its credibility and reduce risk.

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

7 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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"

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

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

INTERSPORT operates in the retail e-commerce sector, focusing on sportswear and equipment for consumers in the Czech Republic. The business model is direct online retail, with a likely large market presence given the brand recognition. The website targets sports enthusiasts and general consumers interested in sporting goods. While the site content is relevant and professionally presented, the lack of explicit business contact information and corporate details in the HTML limits deeper business intelligence insights. No partnerships or subsidiaries are identified from the content. The site’s digital presence suggests a medium to large enterprise with a focus on customer engagement through product offerings and brand consistency.

Security posture

The current security posture of the website is suboptimal. The absence of HTTPS confirmation in the provided data, missing security headers, and lack of visible security policies or incident response contacts indicate potential vulnerabilities. No evidence of secure forms or data protection mechanisms was found. The WHOIS data is missing, which raises concerns about domain registration transparency. There are no indications of malware or phishing, but the site would benefit from implementing standard security best practices such as HTTPS enforcement, security headers, and clear privacy and incident response policies. Compliance with GDPR and other data protection regulations is not demonstrable from the content provided.

Recommendations

  1. Implement and enforce HTTPS with a valid SSL/TLS certificate to secure user data.
  2. Add comprehensive privacy and cookie policies with clear GDPR compliance statements.
  3. Deploy security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish clear contact information including support emails and phone numbers for customer and security incident reporting.
  5. Obtain and publish WHOIS domain registration details to improve transparency and trust.

Technical notes

Notes

The website employs a modern front-end stack with HTML5, CSS3, and JavaScript, including libraries like Swiper.js for sliders and icomoon for icon fonts. The design is responsive and optimized for mobile devices, providing a good user experience. However, no CMS or backend platform is identifiable from the HTML snippet. Performance appears moderate but could be improved with optimization of assets and caching. Accessibility features are basic but present. SEO optimization is good with proper use of headings and meta tags. The lack of visible analytics or tracking scripts suggests minimal user tracking or privacy-focused implementation. Technical debt is not evident but security and compliance technical implementations are lacking.
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.
