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

5 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 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 holds a leading position in the German sports retail market, leveraging a cooperative business model with a large product catalog and multiple brand partnerships. The e-commerce platform supports customer accounts, store locators, and promotional campaigns, indicating a robust revenue stream from online sales and physical store integration. The company targets a broad audience interested in sports and outdoor activities, maintaining consistent branding and trust signals. The use of reputable third-party services and CDNs supports scalability and performance. No suspicious or privacy-protected WHOIS data suggests transparency in operations.

Security posture

The website employs HTTPS with strong SSL configuration and integrates a consent management platform to comply with GDPR. Security best practices such as secure forms, no exposed sensitive data, and reputable third-party scripts are observed. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. No vulnerabilities or malicious indicators were detected in the analyzed content. The security score is high but could be improved by adding explicit security governance documentation and direct security contact channels.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  3. Provide explicit incident response contact channels such as security@ or abuse@ emails.
  4. Regularly audit and update third-party scripts to mitigate supply chain risks.
  5. Enhance transparency by including data retention policies and detailed privacy compliance statements.

Notes

The website uses a modern tech stack including JavaScript ES modules, Algolia for search, and Usercentrics for consent management. Hosting appears to be with Deutsche Telekom, ensuring reliable infrastructure. The site is fast-loading, mobile-optimized, and accessible with good SEO practices. No CMS was explicitly detected, suggesting a custom or proprietary solution. The technical implementation supports a scalable and user-friendly e-commerce experience with integrated marketing and analytics tools. Opportunities exist to improve technical documentation and security header visibility.
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.
