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

10 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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';…

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

The CNLL holds a strong market position as the representative body for open source companies in France, focusing on advocacy, networking, and industry development. Its business model is that of a non-profit association, relying on membership and partnerships. The organization targets startups, software editors, service companies, and consultants in the open source ecosystem. Growth indicators include active news updates, events, and a maintained directory of companies. Partnerships with hosting and design providers like Abilian enhance its operational capabilities. The association's public stances on software patents, open standards, and public procurement reflect its strategic advocacy role.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and no exposed sensitive data. Use of privacy-respecting analytics tools indicates awareness of user privacy. However, the absence of published privacy and cookie policies, incident response contacts, and security frameworks reduces compliance maturity. No security headers were detected in the HTML content, suggesting room for improvement. The site does not expose vulnerabilities or suspicious content, but formalizing security policies and disclosures would strengthen trust and regulatory compliance.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add explicit incident response and vulnerability disclosure policies with contact information.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Regularly audit third-party scripts and analytics tools for privacy and security compliance.

Technical notes

Notes

The website uses a stable and modern technology stack centered on Bootstrap 4.1.1 and jQuery 3.3.1, with Font Awesome icons and Google Fonts for typography. Hosting is provided by Abilian SAS, a professional hosting and design company. Performance is moderate with standard external dependencies. The site is mobile responsive and SEO optimized with proper meta tags. No CMS is detected, indicating a custom or static site approach. Analytics are implemented via Matomo and Ackee, balancing tracking needs with privacy. Technical risks are low, but the absence of security headers and formal policies suggests opportunities for modernization and hardening.
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.
