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

Journées du Logiciel Libre (JdLL) is a well-established non-profit event focused on free software and open source culture, primarily serving the French-speaking community in Lyon, France. The website provides information about the event, its history, and ways to participate or support the initiative. The organization has a mature online presence with a domain registered since 2005 and a consistent branding approach. Technically, the site is built on GravCMS, a modern flat-file CMS, hosted on Infomaniak servers, and is mobile-optimized with good SEO practices. However, it lacks advanced security headers and DNSSEC, which could enhance its security posture. The site does not currently provide privacy or cookie policies, which is a compliance gap, especially under GDPR regulations. No direct contact emails or phone numbers are provided, but social media presence on Mastodon and Peertube supports community engagement. Overall, the site is safe, professional, and trustworthy but could improve in privacy compliance and security best practices.

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

6 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 Policy found

      GDPR requires clear information about cookie usage

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

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

JdLL operates as a niche community event organizer in the technology and non-profit sectors, focusing on free software advocacy. Its competitive advantage lies in its long-standing history since 1998 and strong community ties in Lyon. The business model is primarily event-driven with funding through sponsorships and donations, facilitated by partners like HelloAsso. The target audience includes software enthusiasts, developers, and the general public interested in open source. Growth indicators include ongoing event organization and active social media channels. The partnership ecosystem includes donation platforms and community media hosting. The organization maintains a lean digital footprint with minimal tracking and advertising, aligning with its open-source ethos.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and domain transfer protection. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces its defense-in-depth. No vulnerability disclosure or incident response information is provided, which limits transparency and readiness for security incidents. The lack of privacy and cookie policies also indicates compliance gaps with GDPR. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is adequate for a non-profit event site but could benefit from implementing recommended security best practices and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance browser security.
  3. Publish clear privacy and cookie policies to comply with GDPR and inform users about data handling.
  4. Add explicit contact information for security incidents and consider publishing a security.txt file for vulnerability disclosure.
  5. Regularly review and update the CMS and dependencies to mitigate potential vulnerabilities and maintain performance.

Technical notes

Notes

The website uses GravCMS, a modern flat-file CMS, which reduces complexity and potential attack surface compared to database-driven CMSs. The site is hosted on Infomaniak, a reputable European hosting provider, with DNS managed via Infomaniak nameservers. The HTML is well-structured with proper meta tags and Open Graph data for SEO and social sharing. CSS and JavaScript assets are loaded locally, indicating control over resources. Performance is moderate with no heavy external scripts detected. Mobile optimization is good, with responsive navigation menus. Accessibility is basic but could be improved with ARIA roles and better semantic markup. No analytics or tracking scripts were found, aligning with privacy-conscious design. Overall, the technical infrastructure is solid but could be enhanced with additional security and accessibility improvements.
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.
