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

Le Marathon Vert is an established regional marathon event organizer based in Rennes, Brittany, France. The website serves as the official portal for marathon-related information including race details, registration links, results, and sustainability initiatives. The organization targets runners and sports enthusiasts, providing a comprehensive digital presence with social media integration and volunteer coordination. The business model centers on event management and community engagement with a focus on environmental responsibility. Technically, the website employs a custom CMS and integrates modern tracking and analytics tools such as Google Analytics and Google Tag Manager with IP anonymization. Cookie consent is managed via tarteaucitron.js, reflecting a commitment to privacy compliance, although no explicit privacy policy page was found. The site is mobile-optimized and offers good navigation and content quality, though some security best practices like security headers and vulnerability disclosure policies are absent. From a security perspective, the site uses HTTPS and anonymizes user IPs in analytics, but lacks visible security headers and formal incident response contacts. WHOIS data is unavailable or protected, which is common for event sites, and does not raise immediate concerns. Overall, the site demonstrates a moderate to good security posture with room for improvement in transparency and policy disclosures. The overall risk is low, with recommendations to enhance security headers, publish privacy and terms policies, and establish vulnerability disclosure mechanisms to strengthen trust and compliance. The website is professional, trustworthy, and well-positioned within its niche, serving its audience effectively.

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

4 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Le Marathon Vert holds a strong regional position as a marathon event organizer in Brittany, France. Its competitive advantage lies in its comprehensive event offerings, including multiple race formats and sustainability programs. Revenue streams likely include race registrations, sponsorships, and partnerships. The target customer segment includes amateur and professional runners, local communities, and environmental advocates. Growth indicators include active social media presence and ongoing event editions. The partnership ecosystem includes local sponsors and volunteer networks. Strategic observations suggest leveraging digital tools for enhanced participant engagement and expanding sustainability initiatives to differentiate further.

Security posture

The current security maturity level is moderate. The site enforces HTTPS and anonymizes IP addresses in analytics, which are positive indicators. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, limiting transparency and preparedness. GDPR compliance is partially addressed through cookie consent but lacks a formal privacy policy. Data protection practices appear basic, with no exposed sensitive data detected. The security culture could be improved by formalizing policies and enhancing technical controls.

Recommendations

  1. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options) to mitigate common web attacks.
  2. Publish a detailed privacy policy and terms of service to improve GDPR compliance and user trust.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Add incident response contact information to enhance transparency and readiness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses a custom CMS with modern JavaScript libraries and integrates Google Analytics and Tag Manager for tracking. Cookie consent is managed with tarteaucitron.js, indicating attention to privacy. Performance is moderate with good mobile optimization. SEO is supported by proper meta tags and structured data (JSON-LD). However, the lack of security headers and incomplete WHOIS data suggest areas for technical improvement. Hosting provider details are not evident. The site could benefit from enhanced accessibility features and performance optimizations to improve user experience and 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.
