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

4 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Adidas CZ operates as an enterprise-level e-commerce retailer within the sportswear sector, leveraging the global adidas brand. The business model focuses on direct online sales to consumers in the Czech Republic, supported by a broad network of related adidas domains worldwide. The company benefits from strong brand recognition, consistent branding, and a mature digital presence. Revenue streams are primarily from product sales, with marketing and analytics tools integrated for customer insights. The partnership ecosystem includes global adidas domains and trusted third-party service providers for analytics and tag management. The site reflects a strategic focus on digital retail growth and customer engagement in the regional market.

Security posture

The security maturity of the website is high, with HTTPS enforced and modern security headers likely in place. The site uses reputable third-party monitoring and analytics services, reducing risk of vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit privacy and cookie policies and lack of visible incident response contacts represent compliance gaps. There is no evidence of a security.txt or vulnerability disclosure program. The site would benefit from publishing clear privacy and security policies and providing dedicated security contact channels to enhance incident response readiness and regulatory compliance.

Recommendations

  1. Publish clear and accessible privacy and cookie policies on the website to improve GDPR compliance and user trust.
  2. Add visible contact information including support emails and phone numbers to facilitate customer and security incident communication.
  3. Implement and publicize a security.txt file or vulnerability disclosure policy to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced via dependencies.
  5. Enhance transparency around data collection and retention policies to align with privacy best practices and regulations.

Notes

The website leverages a modern technology stack centered on React and Next.js, enabling server-side rendering and fast client-side interactivity.

Monitoring tools like Instana and Tealium are integrated for real-time performance and analytics tracking.

Opportunities exist to enhance privacy compliance and incident response capabilities through additional policy publication and contact mechanisms.
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.
