Medium risk. 4 critical or high findings in Security headers and SSL/TLS.

Risk levelMedium

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

Kantar Worldpanel operates as a leading global provider of consumer panel research and consumer behavior insights, offering services such as retail surveys and shopper research. The website content reflects a professional and consistent brand presence targeting businesses seeking market research data. Technically, the site employs modern JavaScript libraries like MooTools and integrates Google Tag Manager and Cookiebot for analytics and privacy compliance, though no major CMS or hosting provider is explicitly identified. Security posture is moderate, with HTTPS implied but no explicit security headers detected, and privacy compliance is partial with a cookie consent mechanism but no visible privacy policy page. Overall, the domain WHOIS data is unavailable, which reduces trust but the website content aligns with the known Kantar brand. Strategic recommendations include enhancing privacy disclosures, improving security headers, and publishing clear contact and incident response information.

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 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

  • Email security: did not complete in this scan.
  • 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

Kantar Worldpanel holds a strong market position in the media sector, specializing in consumer panels and market research services. Their business model focuses on providing data-driven insights to enterprises and organizations. The website indicates partnerships with entities like Kantar Media and StackAdapt, supporting marketing and analytics functions. The absence of detailed company registration or contact information online suggests a need for improved transparency. The extensive use of tracking and marketing cookies indicates a data-driven approach to customer engagement and advertising. Growth potential is supported by the enterprise scale and global reach implied by the brand.

Security posture

The website demonstrates a moderate security maturity level, with HTTPS usage and cookie consent management via Cookiebot. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options, and absence of a published security policy or incident response contacts, represent compliance and operational gaps. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. GDPR compliance is partially addressed through cookie consent but lacks comprehensive privacy policy documentation. Incident response readiness and security culture indicators are not evident from the content. Enhancing these areas would reduce risk and improve stakeholder trust.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a detailed and accessible privacy policy and terms of service pages to improve compliance and transparency.
  3. Add explicit contact information for security and compliance inquiries, including incident response and data protection officer contacts.
  4. Introduce a security.txt file and vulnerability disclosure program to facilitate responsible reporting.
  5. Enhance mobile optimization and accessibility to improve user experience and compliance with accessibility standards.

Technical notes

Notes

The website uses a custom tech stack with MooTools JavaScript libraries and integrates third-party services such as Google Tag Manager and Cookiebot for analytics and privacy management. The site employs multiple CSS stylesheets and scripts for UI components like slideshows and sortable lists. Performance is moderate with asynchronous script loading and basic mobile viewport settings. No major CMS or hosting provider is identified, suggesting a bespoke or enterprise hosting environment. Technical debt appears low but opportunities exist to modernize frameworks and improve accessibility and mobile responsiveness.
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.
