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

Théâtre le douze dix-huit is a cultural venue based in Grand-Saconnex, Switzerland, offering a rich program of theatrical, cinematic, musical, and youth-oriented performances for the 2025-26 season. The website serves as an information and ticketing portal, linking to a partner ticketing platform. The business targets a general audience interested in arts and culture, operating as a small-sized institution with a local/regional focus. Technically, the website is built on WordPress using the Divi theme and Essential Grid plugin, with integrations for Google Analytics and Google Tag Manager. The site is hosted likely by Infomaniak, a Swiss hosting provider, and demonstrates moderate performance and good mobile optimization. SEO and accessibility are adequately addressed, though some improvements are possible. From a security perspective, the site uses HTTPS with good SSL configuration but lacks explicit security headers and formal privacy or cookie policies, which are important for GDPR compliance. No vulnerabilities or exposed sensitive data were detected. The absence of a vulnerability disclosure or security.txt file indicates room for improvement in transparency and incident response readiness. Overall, the website is professional and trustworthy, with a solid business presence and technical foundation. However, it should enhance privacy compliance and security best practices to reduce risk and improve user trust.

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

8 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 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

    • 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

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 theater operates in the hospitality and non-profit cultural sector, focusing on live performances and community engagement. Its business model revolves around ticket sales, subscriptions, and event programming. The partnership with Infomaniak for ticketing indicates a strategic collaboration to streamline sales. The website's content and structure suggest a well-established local institution with consistent branding and active social media engagement. Growth opportunities may include expanding digital presence and enhancing compliance to meet evolving regulatory requirements.

Security posture

The current security posture is moderate to good, with HTTPS enforced and no visible sensitive data leaks. However, the lack of security headers and formal policies reduces the overall security maturity. The site does not provide explicit incident response contacts or vulnerability disclosure mechanisms, which are best practices for modern web security. Compliance with GDPR is partial due to missing privacy and cookie policies. The use of third-party analytics and ticketing services introduces additional risk vectors that should be managed through clear data processing agreements and transparency.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy accessible from the website footer.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file or vulnerability disclosure page to facilitate responsible reporting.
  4. Include explicit GDPR compliance statements and consent mechanisms for tracking technologies.
  5. Provide clear contact information for security incidents and data protection inquiries.

Technical notes

Notes

The website leverages a modern WordPress CMS with a popular premium theme (Divi) and essential plugins for content display and ticketing integration. Google Fonts and Google Analytics are used for design and analytics respectively. The site is mobile optimized and SEO friendly with structured data implemented via JSON-LD. Performance is moderate, with potential improvements in caching and resource optimization. No deprecated or vulnerable libraries were detected in the provided data. Hosting appears stable and appropriate for the business scale.
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.
