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

The website www.grand-saconnex.ch serves as the official digital presence of the municipality of Grand-Saconnex in Switzerland. It provides comprehensive information about local government services, community events, social and cultural activities, and practical resources for residents and businesses. The site targets local citizens, businesses, and visitors, positioning itself as a trusted source for municipal information and services. The business model is that of a government entity focused on public service and community engagement. Technically, the website is built on Drupal 10, leveraging modern web technologies such as Bootstrap Icons, Swiper.js, and LightGallery for enhanced user experience. It employs Google Analytics for visitor insights and implements a cookie consent mechanism compliant with GDPR. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. From a security perspective, the website enforces HTTPS and uses cookie consent banners to comply with privacy regulations. No critical vulnerabilities or exposed sensitive data were detected. However, there is room for improvement in publishing explicit security policies and incident response contacts, as well as enhancing HTTP security headers. Overall, the website demonstrates a high level of professionalism, trustworthiness, and compliance with privacy standards. It effectively serves its community with relevant content and functional design, though it could benefit from additional transparency in security and incident management policies.

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 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

Grand-Saconnex operates as a local government authority providing essential municipal services including administration, social support, cultural and sports programming, and economic promotion. Its market position is that of a trusted public institution serving a medium-sized community. The website supports engagement with residents and businesses through digital services like virtual counters and event calendars. The partnership ecosystem includes recognized certifications such as Cité de l'énergie and Label 1 pour tous, enhancing its credibility. Growth indicators include active event promotion and digital newsletter subscriptions. The business model is non-commercial, focused on public service delivery and community well-being.

Security posture

The website exhibits a solid security posture with HTTPS enforced and cookie consent mechanisms in place, reflecting compliance with GDPR. No exposed credentials or sensitive data were found in the HTML content. The use of third-party scripts like Google Analytics is managed with user consent. However, the absence of a published security policy and incident response contacts indicates a gap in transparency and readiness. Security headers such as Content-Security-Policy and X-Frame-Options are not evident, which could be improved to mitigate common web threats. Overall, the site is secure but could enhance its security maturity by formalizing policies and improving HTTP header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user guidance.
  2. Provide clear incident response contact information for reporting security issues.
  3. Implement and configure HTTP security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  5. Enhance transparency by including terms of service and data protection officer contact details.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, ensuring a robust content management framework. It integrates several contemporary front-end libraries such as Bootstrap Icons for UI elements, Swiper.js for interactive sliders, and LightGallery for media display. Google Analytics is used for traffic analysis with consent-based tracking. The site is mobile responsive and includes accessibility features like skip links and ARIA attributes. Performance is moderate, with asynchronous loading of scripts and use of CDNs for fonts and libraries. There is no explicit hosting provider information, but the SSL configuration is excellent, indicating a secure hosting environment. Opportunities exist to optimize security headers and expand technical documentation for better maintainability.
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.
