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

Atmo France operates as the national federation coordinating regional associations responsible for monitoring air quality across France and its overseas territories. The organization provides comprehensive data, alerts, and educational resources to the general public, local authorities, businesses, and educational institutions. Their market position is that of an authoritative, government-aligned non-profit entity focused on environmental health and air quality surveillance. Technically, the website is built on Drupal 9, leveraging modern web technologies such as Bootstrap, Google Fonts, and FontAwesome for styling and responsiveness. Analytics are handled via Matomo, indicating a preference for privacy-conscious tracking. The site is mobile-optimized and accessible, with clear navigation and interactive features such as maps and indices for air quality and pollen. From a security perspective, the site uses HTTPS and includes some anti-bot measures, but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is basic, with no visible privacy or cookie policies, which is an area for improvement. Overall, the website presents a trustworthy and professional front for a public-interest environmental organization. The lack of WHOIS data due to privacy protection is typical for such entities and does not detract from legitimacy. Strategic recommendations include enhancing privacy disclosures, implementing security headers, and publishing clear contact and incident response information to strengthen trust and compliance.

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 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

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

Atmo France holds a strong position as the official federation for air quality monitoring in France, serving a broad audience including citizens, local governments, and businesses. Their non-profit model focuses on data aggregation, public information dissemination, and support for environmental health initiatives. The organization benefits from partnerships with regional air quality associations and maintains an active presence on major social media platforms to engage stakeholders. Growth opportunities lie in expanding data accessibility via APIs and enhancing educational outreach. The federation's operations are aligned with governmental environmental policies, reinforcing its authoritative role in the sector.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and some anti-bot measures in place. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No direct contact channels for security incidents or vulnerability disclosures are provided, which could hinder incident response effectiveness. Privacy compliance is minimal, lacking visible cookie consent mechanisms or detailed privacy policies. There are no indications of vulnerable libraries or exposed sensitive data in the analyzed content. Enhancing security headers, publishing security policies, and establishing incident response contacts would significantly improve the security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit GDPR compliance and consent mechanisms.
  2. Add essential security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting.
  4. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  5. Conduct regular security audits of third-party scripts and libraries to identify and mitigate vulnerabilities.

Technical notes

Notes

The website is built on Drupal 9, a modern and widely supported CMS, ensuring a solid foundation for content management and security updates. The use of Bootstrap and Google Fonts contributes to responsive design and good user experience across devices. Matomo analytics indicates a privacy-focused approach to user tracking. Performance appears moderate, with no major issues detected in the HTML content. Accessibility features such as skip links and ARIA labels are present, enhancing usability for assistive technologies. Opportunities exist to optimize performance further and enhance SEO through richer metadata and structured data implementation.
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.
