The company employs around 600 experts and offers a comprehensive range of cybersecurity services including risk management, compliance, operational security, offensive security, and security technology solutions. Their mission emphasizes protecting organizations from cyber threats while contributing positively to society and the environment.

Technically, the site is built on WordPress with modern frameworks and integrates HubSpot for marketing and analytics.

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 key player in the French cybersecurity market, leveraging independence and a large expert workforce to serve diverse sectors including government and non-profits. Their business model focuses on providing specialized cybersecurity services and managed security operations. The company actively engages in social and environmental initiatives, enhancing its brand reputation. Partnerships with recruitment platforms and digital agencies indicate a mature operational ecosystem. The website content and structure reflect a professional and trustworthy organization with clear service offerings and client engagement channels.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and secure data collection forms that include explicit user consent. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security is a gap. No direct incident response or security policy pages were found, and there is no published vulnerability disclosure or security.txt file. The lack of exposed sensitive data and use of reputable third-party services like HubSpot reduce risk. Overall, the security posture is good but could be enhanced with additional transparency and technical controls.

Recommendations

  1. Implement and publish security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to strengthen browser security.
  2. Create and publish an incident response policy or security policy page to improve transparency and trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide direct security contact information such as a security@ email address for incident reporting.
  5. Regularly review and audit third-party scripts and integrations to minimize potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using modern technologies such as Bootstrap for responsive design and Swiper for carousels. It leverages HubSpot for forms, analytics, and marketing automation, indicating a sophisticated marketing infrastructure. The site is mobile-optimized with good accessibility and SEO practices, including comprehensive meta tags and structured data. Performance is moderate, with room for optimization in loading speed. The absence of hosting provider details limits full infrastructure assessment. Overall, the technical implementation supports a professional and user-friendly experience but could benefit from performance tuning and enhanced security configurations.
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.
