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 sector, leveraging both physical stores and a robust online platform. The company benefits from partnerships with major sports brands such as Adidas, Nike, and The North Face, enhancing its market appeal. Revenue streams primarily come from direct online sales and in-store purchases. The target audience includes general consumers interested in sports and outdoor activities. The website's content and marketing efforts indicate a focus on seasonal promotions and brand-specific campaigns, supporting customer engagement and sales growth. The absence of detailed registrant WHOIS data is typical for large retail businesses and does not detract from credibility. The company ecosystem includes multiple brand shops and promotional campaigns, indicating a mature and well-structured business operation.

Security posture

The website exhibits a mature security posture with HTTPS enforced and integration of a consent management platform (Usercentrics) to comply with privacy regulations. Security headers are implied but not explicitly confirmed in the HTML. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the lack of a publicly available security policy or incident response contact information suggests room for improvement in transparency and readiness. The use of Google Tag Manager and Criteo for marketing introduces moderate tracking, managed via consent. Overall, the site balances user privacy and marketing needs effectively but should consider publishing explicit security and incident response documentation to enhance trust.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options if not already implemented.
  3. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  4. Consider implementing and publishing a vulnerability disclosure policy or security.txt file.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern JavaScript module-based architecture with integration of third-party services such as Usercentrics for consent management, Google Tag Manager for analytics, and Algolia for search functionality. The hosting infrastructure appears to be managed by Deutsche Telekom, indicated by the nameservers. Performance optimizations include responsive images, preloading fonts, and lazy loading of images. SEO is well addressed with canonical URLs, meta descriptions, and structured data for search. Accessibility features such as skip links and ARIA labels are present, enhancing usability. The technical stack is robust and scalable, supporting a large product catalog and dynamic content. Opportunities exist to enhance security header visibility and formalize security documentation.
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.
