0–100, higher is better. How it is calculated

Comgest S.A. is a well-established independent international asset management group founded in 1985, specializing in long-term quality growth investment strategies with a strong emphasis on responsible investing (ESG). The company targets investors worldwide who share a long-term investment horizon. The website reflects a professional and consistent brand image, providing comprehensive information about their business, investment approach, and sustainability commitments. Technically, the site employs modern technologies including Google Tag Manager and OneTrust for cookie consent, ensuring compliance with privacy regulations and user tracking transparency. The site is mobile-optimized, accessible, and SEO-friendly, offering a positive user experience. Security-wise, the website uses HTTPS and cookie consent mechanisms but lacks explicit security headers and a published security policy or incident response contacts, which could be improved. Overall, the domain registration and WHOIS data align well with the company's claims, supporting legitimacy and trustworthiness.

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

5 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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';…

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

Comgest operates in the finance sector as an asset management firm with a focus on quality growth and ESG investing. Their business model centers on managing investment funds for private and professional investors globally. The company maintains a strong market position with a long history and international presence. Their partnership with The Comgest Foundation highlights corporate sustainability efforts. The website's multilingual support and audience targeting indicate a strategic approach to global markets. Revenue streams likely derive from asset management fees. The absence of direct contact emails or phone numbers on the main page suggests controlled communication channels, possibly to manage client interactions professionally.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and a cookie consent mechanism compliant with GDPR. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security hardening. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact information is a gap in transparency and readiness. The use of third-party scripts like Google Tag Manager and OneTrust is standard but requires ongoing monitoring for vulnerabilities. Overall, the security posture is adequate but could benefit from enhancements in headers and incident response disclosures.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency by providing direct contact emails or phone numbers for customer support and security issues.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website uses a modern tech stack including JavaScript, Google Tag Manager for analytics, and OneTrust for cookie consent management. The site is responsive and optimized for mobile devices, with good accessibility features. The HTML structure is valid and SEO-friendly with appropriate meta tags and Open Graph data. No CMS or hosting provider was explicitly detected from the HTML content. Performance appears moderate, with large images and embedded Vimeo video content. There is an opportunity to improve technical SEO and security headers. The site architecture supports multilingual content and regional audience targeting, indicating a mature digital infrastructure.
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.
