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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  2. 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';…

  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

M6 Unlimited operates as an essential entity within the media advertising industry, targeting advertisers and media buyers in France. Its business model revolves around selling advertising space across multiple media channels and providing creative agency services. The company benefits from its affiliation with Groupe M6, enhancing its market credibility and reach. The website showcases client testimonials and detailed service offerings, indicating a customer-centric approach. Partnerships and related domains such as recruitment and e-commerce sites support its ecosystem. Growth indicators include the launch of innovative platforms like My6 and active content marketing through news and insights.

Security posture

The website demonstrates a good security posture with HTTPS enabled and domain registration protections such as clientTransferProhibited status. Cookie consent and privacy policies are comprehensive and GDPR compliant. However, the absence of a published security policy, incident response contacts, and security.txt file suggests room for improvement in transparency and vulnerability management. The use of third-party analytics and marketing scripts is standard but requires ongoing monitoring to mitigate risks. No vulnerabilities or exposed sensitive data were detected in the HTML content.

Recommendations

  1. Publish a dedicated security policy page and provide incident response contact information to enhance transparency.
  2. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and plugins for security vulnerabilities and update them promptly.
  5. Maintain and document data retention policies for analytics and user data to strengthen privacy compliance.

Technical notes

Notes

The website is powered by WordPress CMS, leveraging modern SEO and analytics tools including Yoast SEO, Google Tag Manager, Matomo, and Hotjar. It uses asynchronous script loading and CSS preloading for performance optimization. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. Hosting details are limited but domain registration is managed by GANDI, a reputable registrar. The site loads quickly and has a clean, professional design with structured data (JSON-LD) for enhanced SEO. Technical risks are minimal, primarily related to the need for enhanced security headers and formal security documentation.
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.
