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

Atmosphères 53 is a small non-profit cultural association based in Mayenne, France, dedicated to cinema programming, cultural mediation, and organizing film festivals and educational cinema activities. The website serves as a regional hub for cinema-related events, schedules, and cultural projects, targeting a general audience interested in film and culture within the Mayenne region. The business model focuses on cultural promotion rather than commercial sales, positioning itself as a key regional player in cinema culture. Technically, the website is built on WordPress with common plugins such as Yoast SEO and WP Rocket, leveraging jQuery and bxSlider for interactive elements. The site is mobile-optimized and uses HTTPS with Google Analytics and Tag Manager for visitor tracking. Security posture is good with HTTPS enforced, but lacks explicit security headers and a cookie consent mechanism, which are recommended for GDPR compliance. WHOIS data is unavailable due to privacy protection, which is reasonable for this type of organization. Overall, the website is professional, trustworthy, and well-maintained, though improvements in privacy compliance and security headers would enhance its posture.

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. 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

The organization operates in the cultural sector, specifically cinema and arts education, serving the Mayenne community. Its competitive advantage lies in its regional focus and comprehensive programming of cinema events, festivals, and educational initiatives. Revenue streams likely include membership fees, donations, and public funding typical for non-profits. The partnership ecosystem includes local cinemas and cultural institutions, as indicated by linked partner domains. The website content and structure support community engagement and cultural outreach, with a clear focus on film enthusiasts and educational groups. Growth indicators include active event scheduling and festival promotion. The absence of direct contact details on the homepage suggests a focus on public information rather than direct sales or commercial transactions.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, which limits transparency in security management. GDPR compliance is partially addressed via a privacy policy, but the lack of a cookie consent banner and explicit data retention policies indicates gaps. The use of up-to-date WordPress plugins and themes is assumed but should be regularly verified to mitigate vulnerabilities. Overall, the security posture is adequate for a small cultural website but could be improved with standard best practices and transparency measures.

Recommendations

  1. Implement a cookie consent banner to comply fully with GDPR requirements.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-XSS-Protection) to enhance protection.
  3. Publish a security policy and provide incident response contact information to improve transparency and trust.
  4. Regularly audit and update WordPress core, themes, and plugins to reduce vulnerability risks.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on WordPress CMS with a technology stack including jQuery, bxSlider for sliders, FontAwesome for icons, and Google Analytics/Tag Manager for analytics. The site uses WP Rocket for caching and performance optimization. The HTML is well-structured with proper meta tags and SEO optimizations via Yoast SEO plugin. Mobile responsiveness is good, and the site loads with moderate speed. Accessibility features are basic but present. No advanced frameworks or custom backend technologies are detected. Hosting provider details are not disclosed. The site could benefit from enhanced security headers and a cookie consent mechanism to improve compliance 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.
