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

ATMO GrandEst operates as a regional environmental monitoring organization focused on air quality and pollen indices for the Grand Est region in France. The website provides detailed geographic and environmental data for numerous communes, serving residents and local authorities. The business model aligns with public service and environmental data dissemination, positioning ATMO GrandEst as a key regional authority in environmental monitoring. Technically, the website is built on Drupal 9 CMS, utilizing modern web fonts, icon libraries, and analytics tools such as Microsoft Clarity and Google Analytics. The site demonstrates moderate performance and good mobile optimization but lacks advanced SEO and accessibility features. Security practices include HTTPS usage and asynchronous loading of tracking scripts, though security headers and explicit privacy mechanisms are not evident. The security posture is moderate with no detected vulnerabilities or WAF blocking. However, the absence of visible privacy and cookie policies, as well as contact information, reduces privacy compliance and user trust. The WHOIS data is unavailable due to EURid privacy restrictions, which is typical for .eu domains, and does not raise immediate legitimacy concerns. Overall, the website is functional and serves its informational purpose but would benefit from enhanced privacy compliance, clearer contact channels, and improved security headers to strengthen trust and regulatory adherence.

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

7 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 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 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

ATMO GrandEst holds a strategic position as a regional environmental monitoring entity in France's Grand Est region. Its competitive advantage lies in providing localized, real-time air quality and pollen data to public stakeholders. The business model is primarily public service-oriented, likely funded by governmental or regional bodies. The target customer segments include residents, local governments, and environmental agencies. Growth indicators are not explicit but the extensive geographic data coverage suggests a mature operational scope. The partnership ecosystem includes technology providers for analytics and web infrastructure but no direct business partners are identified. Strategic observations highlight the need for improved digital maturity in privacy and security compliance to maintain public trust and meet evolving regulatory requirements.

Security posture

The current security maturity level is moderate. The website employs HTTPS and uses asynchronous loading for analytics scripts, reducing page load impact. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security indicates room for improvement. No exposed sensitive data or vulnerable libraries were detected in the provided content. Compliance gaps exist due to missing privacy and cookie policies, which are critical under GDPR. Incident response readiness and security culture indicators are not evident from the content. The absence of a security.txt or vulnerability disclosure policy limits transparency. Overall, the security posture is adequate for informational content but requires enhancements to meet best practices and regulatory standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Publish clear contact information including support and security incident response channels.
  4. Establish and publish a vulnerability disclosure policy or security.txt file.
  5. Enhance accessibility and SEO features to improve user experience and search visibility.

Technical notes

Notes

The website is built on Drupal 9 CMS, leveraging Google Fonts and FontAwesome for UI elements. It integrates Microsoft Clarity and Google Analytics for user behavior tracking. The site uses asynchronous script loading to optimize performance. Mobile optimization is good, but accessibility features are basic. The HTML structure is valid with proper meta tags, though SEO optimization is minimal. Hosting provider details are not explicit. The technical stack is modern but could benefit from enhanced security configurations and privacy compliance mechanisms. Performance is moderate, with potential for improvement through caching and content delivery optimizations.
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.
