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. GDPR outside view

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

    • 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: LinkedIn, YouTube

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

  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

  • 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

Advens positions itself as a leader independent cybersecurity firm in France, targeting sectors such as healthcare, public administration, and industry. Their competitive advantage lies in their independence, large expert workforce, and integrated service offerings including SOC and offensive security. The company leverages partnerships and a strong ecosystem, including media and recruitment platforms, to support growth. Their engagement in social impact projects and clear branding enhance their market reputation. Revenue streams likely include consulting, managed security services, and compliance support. The website content and structure reflect a mature organization with strategic focus on both business and societal impact.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and clientTransferProhibited domain status. The presence of ISO 27001 certification indicates adherence to recognized security standards. No exposed sensitive data or vulnerable libraries were detected. Forms include GDPR-compliant consent mechanisms. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security are areas for improvement. No explicit incident response or security contact information was found, which could be enhanced to improve transparency and readiness. Overall, the security posture is strong but could benefit from additional technical controls and published policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  5. Regularly audit third-party scripts and tracking pixels to ensure privacy compliance and minimize tracking footprint.

Technical notes

Notes

The website is built on WordPress CMS with Bootstrap framework, integrating HubSpot for forms, analytics, and marketing automation. The site uses modern web fonts and responsive design techniques ensuring excellent mobile optimization and accessibility. Performance is moderate, with room for optimization in loading times. The use of Swiper carousel and lazy loading images enhances user experience. Hosting details are limited but domain registrar is EuroDNS S.A. The site lacks DNSSEC and some security headers, which are recommended for improved security posture. Overall, the technical infrastructure is solid and supports the business needs effectively.
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.
