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

1 finding 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Criteo operates in the technology and media sectors, focusing on advertising technology. Their business model is B2B, offering marketing and retargeting solutions that leverage data analytics. The company targets advertisers and e-commerce businesses seeking to optimize digital marketing campaigns. Their competitive advantage lies in their advanced technology platform and global reach. The website content and structured data confirm a large enterprise with consistent branding and a clear market position. Partnerships and integrations with major analytics and marketing platforms are evident through linked domains and scripts. The company maintains a strong digital presence with active social media channels and comprehensive legal and privacy documentation.

Security posture

The website employs HTTPS and includes security headers inferred from scripts and event listeners. It uses cookie consent mechanisms and privacy policies aligned with GDPR compliance. The presence of New Relic monitoring indicates active performance and error tracking. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure programs suggests areas for improvement. No obvious vulnerabilities or exposed sensitive data were detected in the content. The domain WHOIS is privacy protected, which is typical for large corporations but limits transparency. Overall, the security posture is good but could be enhanced by publishing more explicit security governance information.

Recommendations

  1. Publish a dedicated security policy page detailing security governance and controls.
  2. Implement and publicize a vulnerability disclosure program including a security.txt file.
  3. Provide clear incident response contact information for security issues.
  4. Enhance website accessibility to meet higher standards for inclusivity.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including jQuery, Font Awesome, and Slick Carousel. It integrates Google Tag Manager and New Relic for analytics and monitoring. The site uses Yoast SEO for search engine optimization and includes structured data in JSON-LD format for rich search results. Performance is moderate with preloading of fonts and stylesheets. Mobile optimization is good with responsive meta tags and viewport settings. Accessibility is basic but could be improved. Hosting provider details are not explicit. Overall, the technical infrastructure supports a professional and scalable web presence suitable for a large enterprise.
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.
