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. 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 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

    • High

      Third-party services without privacy policy

      Detected services: Twitter, LinkedIn

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

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.

Business context

Business profile

Dematis operates a B2B SaaS model targeting government and local authorities in France, providing essential digital transformation tools for document dematerialization and secure electronic transactions. Its competitive advantage lies in its comprehensive suite of specialized platforms, long-standing market presence since 2003, and official certifications. The company maintains a strong partnership ecosystem with multiple branded service domains. Revenue streams likely derive from subscription and service fees for its platforms. The company demonstrates consistent branding and a clear focus on compliance and security, appealing to regulated sectors. Growth indicators include a large user base and high transaction volumes. Strategic observations suggest continued investment in security enhancements and privacy compliance to maintain trust and market leadership.

Security posture

Dematis exhibits a mature security posture with mandatory HTTPS, domain registration protections, and certifications supporting legal compliance. However, the absence of DNSSEC and security headers like Content-Security-Policy and Strict-Transport-Security indicates room for improvement. No incident response or security policy information is publicly available, which could hinder rapid response to security events. The lack of a cookie consent mechanism may pose GDPR compliance risks. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security maturity is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options) to mitigate common web attacks.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Introduce a cookie consent mechanism to ensure full GDPR compliance and user privacy control.
  5. Regularly audit third-party scripts and dependencies to avoid vulnerabilities and maintain secure operations.

Technical notes

Notes

The website uses a modern and stable technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and FontAwesome for icons. Hosting is provided by OVH sas, a reputable provider. The site loads moderately fast with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags and structured navigation. No CMS was detected, suggesting a custom or static site approach. There is no evidence of analytics or tracking scripts, indicating a privacy-conscious implementation. Technical risks include lack of DNSSEC and missing security headers, which could be addressed to reduce attack surface and improve security posture.
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.
