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

Atmo Hauts-de-France operates as a regional air quality observatory dedicated to monitoring atmospheric pollution and raising awareness among local authorities, businesses, and citizens in the Hauts-de-France region of France. The organization provides data, maps, and health advice related to air quality, positioning itself as a key environmental public service entity in the region. The website is professionally designed using Drupal 9 CMS and integrates modern analytics tools such as Matomo and Microsoft Clarity, indicating a moderate level of digital maturity and user engagement tracking. Security posture is adequate with HTTPS implied, but lacks explicit security headers and detailed privacy or cookie policies, which are areas for improvement. Overall, the domain appears legitimate and active, though WHOIS data is privacy-protected and unavailable. The site content is safe, relevant, and targeted at a general audience interested in environmental health.

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

9 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

  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 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';…

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 organization serves a government and non-profit sector role focused on environmental monitoring and public health. Its market position is that of a regional authority providing essential air quality data and educational resources. The business model is service-oriented, likely funded by public or regional government sources, targeting local municipalities, enterprises, and the general public. The website's content quality and branding consistency support a trustworthy image. The use of open-source CMS and analytics tools suggests cost-effective digital operations. No direct partnerships or subsidiaries are evident from the data. Growth indicators include regular data updates and integration of user engagement analytics, supporting ongoing service improvement.

Security posture

The website employs HTTPS, ensuring encrypted communications, and uses reputable analytics platforms. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The lack of explicit privacy and cookie policies, as well as missing incident response or security contact information, indicates gaps in compliance and user trust mechanisms. Overall, the security maturity is moderate but could be enhanced by implementing recommended headers, formalizing privacy compliance, and publishing incident response details.

Recommendations

  1. Implement comprehensive privacy and cookie policies clearly accessible on the website.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to improve security posture.
  3. Publish clear contact information including security incident response channels.
  4. Regularly audit and update third-party scripts and analytics tools for vulnerabilities.
  5. Enhance accessibility features and provide detailed GDPR compliance statements.

Technical notes

Notes

The website is built on Drupal 9, a modern and widely supported CMS, indicating a solid technical foundation. It uses JavaScript-based analytics tools (Matomo and Microsoft Clarity) for user behavior tracking. The site is mobile-optimized with responsive design elements and proper viewport settings. Performance is moderate, with some inline styles and scripts that could be optimized further. SEO is supported by canonical and shortlink tags, meta descriptions, and structured JSON data for air quality indices. No hosting provider details were found. The site would benefit from improved accessibility features and enhanced security configurations to reduce technical risks.
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.
