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

Trans Europe Halles is a well-established non-profit network uniting over 170 grassroots arts and culture centres across more than 40 European countries. Founded in 1983, it focuses on reclaiming abandoned spaces and transforming them into vibrant cultural hubs, promoting social and environmental justice. The organization supports its members through events, workshops, and community initiatives, positioning itself as a key player in the European cultural sector. Technically, the website is built on modern web technologies including Wagtail CMS, Bootstrap, and JavaScript frameworks, with good mobile optimization and SEO practices. The presence of Google Analytics and Mailchimp indicates active user engagement and marketing efforts. However, some technical improvements could be made, such as adding explicit security headers and publishing security policies. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, reflecting good privacy compliance with GDPR. Nonetheless, the absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. No direct contact emails or phone numbers were found, which may impact business credibility. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website presents a professional and trustworthy front for a cultural non-profit organization, but verification of domain registration and enhanced security disclosures are recommended to strengthen trust and compliance.

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

5 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Trans Europe Halles operates as a non-profit network focused on grassroots cultural centres, leveraging a community-driven business model. Its competitive advantage lies in its extensive European network and long-standing history since 1983. Revenue streams likely include membership fees, grants, and event sponsorships. The target customers are cultural practitioners and community organizations seeking support in arts and culture initiatives. The organization maintains partnerships with regional governments and European cultural bodies, enhancing its legitimacy and reach. Growth indicators include active event scheduling and calls for technical volunteers, signaling ongoing development and engagement.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and cookie consent compliance. However, the lack of visible security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces its defense-in-depth posture. No incident response or vulnerability disclosure information is published, which limits transparency and preparedness. The absence of WHOIS data is a notable gap, potentially impacting trustworthiness. Overall, the security posture is adequate for a non-profit cultural organization but could be improved by adopting best practices in security headers, publishing policies, and verifying domain registration.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add essential security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Verify and update WHOIS domain registration information to ensure transparency and trust.
  4. Provide direct company contact emails and phone numbers to improve business credibility and user trust.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a modern technology stack with Wagtail CMS, Bootstrap for responsive design, and JavaScript for interactivity. Google Tag Manager and Google Analytics are integrated for tracking and marketing purposes. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate with video content and images, but no major technical debt or errors were detected. Opportunities exist to improve accessibility and implement additional security headers. Hosting provider details are not explicitly identified from the content.
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.
