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

3 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';…

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

Kantar's market positioning as a global data and insights leader is supported by its comprehensive service offerings and strong parent company backing. The business model focuses on delivering actionable insights to brands and marketers, with revenue streams likely from consulting, analytics platforms, and syndicated research. The company targets enterprise clients seeking data-driven brand and sales strategies. Partnerships with Salesforce, Workday, and Pardot enhance its marketing and operational capabilities. Growth indicators include a broad technology stack and extensive use of third-party analytics and advertising platforms. The website's content and structure reinforce Kantar's authoritative market presence and commitment to data privacy and user consent.

Security posture

Kantar exhibits a mature security posture with enforced HTTPS, robust security headers, and cookie consent mechanisms that comply with GDPR. The presence of CSRF tokens and session management cookies indicates attention to secure user interactions. However, the absence of a dedicated security policy page, vulnerability disclosure program, or incident response contact information suggests areas for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analysis. The security score reflects good practices but highlights the need for enhanced communication of security governance to users and stakeholders.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and practices.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance cookie consent transparency and ensure ongoing compliance with evolving privacy regulations.

Technical notes

Notes

The website is built on a modern technology stack utilizing JavaScript frameworks, Google Tag Manager, and Cookiebot for consent management. Hosting appears to be on Microsoft Azure, providing scalability and reliability. Performance is moderate with room for optimization, particularly in loading speed. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. The use of multiple analytics and marketing tools indicates a sophisticated digital marketing infrastructure. Technical risks are minimal but include dependency on third-party scripts which require continuous monitoring. Opportunities exist to improve performance and security transparency to further strengthen the technical foundation.
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.
