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

Certidemat is a specialized provider of electronic signature certificates compliant with eIDAS and RGS standards, primarily serving businesses and public entities in France. The company operates under the parent brand Dematis and offers digital trust services that facilitate secure electronic signatures for public procurement, legal acts, and other dematerialization processes. The website reflects a focused business model targeting compliance-driven digital certification needs within the French market. Technically, the website employs a modern technology stack including jQuery, FontAwesome, Google Fonts, and integrates third-party services such as Didomi for consent management, Tawk.to for live chat support, and Google Analytics for traffic analysis. The site is well-structured with good mobile optimization and basic accessibility features, providing a professional user experience. From a security perspective, the site enforces HTTPS and implements GDPR-compliant cookie consent mechanisms. However, there is a lack of explicit security headers and no visible incident response or vulnerability disclosure information. The absence of WHOIS registration data is a notable concern, potentially impacting trustworthiness despite the professional presentation and active business presence. Overall, Certidemat presents a solid digital presence with good privacy compliance and business credibility, but the missing WHOIS data and limited security policy disclosures suggest areas for improvement to enhance trust and security posture.

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

8 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 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';…

  2. 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

      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

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

Certidemat occupies a niche market segment focused on electronic signature certificates compliant with European and French regulatory standards. Its competitive advantage lies in its specialization and integration with public sector digital processes such as ACTES, PESv2, and public procurement. The business model is B2B, generating revenue through certificate sales and related digital trust services. The company leverages a network of partner domains under the Dematis umbrella, enhancing its ecosystem and service offerings. Growth indicators include a clear market focus and established presence since 2003. Strategic partnerships and compliance certifications strengthen its market position, although transparency in domain registration could be improved.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR-compliant consent management in place. The use of third-party scripts like Tawk.to and Google Analytics introduces typical tracking risks but is managed with user consent. The absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published incident response plan or security contact channels limits the organization's readiness to handle security incidents. Compliance with GDPR is evident, but further enhancements in security best practices and transparency are recommended.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen site security.
  2. Publish an incident response policy and provide clear security contact channels to improve transparency and readiness.
  3. Verify and update WHOIS domain registration information to enhance domain legitimacy and trustworthiness.
  4. Conduct regular security audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a traditional web stack using jQuery and FontAwesome, with Google Fonts for typography. It integrates several third-party services including Didomi for consent management, Tawk.to for live chat, and Google Analytics for visitor tracking. The site uses responsive design techniques and includes SEO-friendly meta tags. Performance is moderate, with potential improvements in loading speed by optimizing scripts and assets. No CMS was detected, suggesting a custom or static site architecture. The technical implementation is solid but could benefit from modernization 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.
