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 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

Havas Media Network holds a strong market position as a rapidly growing global media network, leveraging its parent company Havas Group's reputation. Its business model centers on delivering integrated media solutions powered by data and technology to global brands. The company targets large enterprises and multinational clients, offering specialized services across media planning, e-commerce, data analytics, and cultural engagement. The presence of major global clients and a comprehensive service portfolio indicates robust revenue streams and competitive advantages. The company’s digital ecosystem and global footprint support scalability and innovation, positioning it well for continued growth in the media and advertising sector.

Security posture

The security posture of Havas Media Network’s website is solid, with HTTPS enforced and domain transfer protections in place. No critical vulnerabilities or exposed sensitive data were detected. The absence of DNSSEC and security headers represents moderate gaps that could be addressed to strengthen defenses against DNS spoofing and clickjacking attacks. There is no publicly available incident response or vulnerability disclosure information, which could improve transparency and trust. Privacy policies and cookie consent mechanisms are comprehensive and GDPR compliant, reflecting a mature approach to data protection. Overall, the site’s security maturity is good but could benefit from formalized security documentation and enhanced DNS security.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and enhance domain security.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to mitigate common web vulnerabilities.
  3. Publish a formal security policy and incident response plan accessible on the website to improve transparency and preparedness.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with evolving regulations.

Notes

The website is built on WordPress, leveraging modern JavaScript libraries like Swiper.js for interactive elements and Google Tag Manager for analytics and marketing. Hosting is provided by Gandi SAS, a reputable registrar and DNS provider. The site demonstrates fast loading times, mobile responsiveness, and good SEO practices including meta tags and structured data (JSON-LD). Accessibility features such as skip links and ARIA labels are present, enhancing usability. The technical stack is modern and well-maintained, though enabling DNSSEC and adding security headers would further improve the technical security posture. Overall, the infrastructure supports a high-quality user experience with scalable and maintainable technology choices.
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.
