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

3 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. 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

ADFC is positioned as a leading non-profit in the transportation sector focused on cycling advocacy in Germany. Its competitive advantage lies in its large membership base, comprehensive service offerings including roadside assistance, and strong political engagement. The business model centers on membership fees, donations, and advocacy activities. Target customers include everyday cyclists, policymakers, and cycling enthusiasts. Growth indicators include the establishment of a federal youth organization and active event participation. Partnerships with related organizations and campaigns like radvolution.de enhance its ecosystem. The organization's operations reflect a well-established, large-scale non-profit with significant market influence.

Security posture

The website demonstrates a good security posture with enforced HTTPS and a robust cookie consent mechanism aligned with GDPR. Use of Matomo analytics with disabled cookies indicates privacy-conscious data collection. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security policies or incident response contacts are gaps. No vulnerabilities or sensitive data exposures were found in the HTML content. The organization should consider formalizing security policies and improving header configurations to strengthen defenses and transparency.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities.
  4. Enhance transparency around data retention policies and user privacy practices.
  5. Maintain and update cookie consent mechanisms to reflect evolving privacy regulations.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system, indicating a stable technical foundation. Integration of modern JavaScript libraries and icon fonts enhances user experience. Analytics and marketing tools are implemented with user consent, reflecting good privacy practices. The site is mobile-optimized and accessible, with good SEO metadata. Performance is moderate, with potential for optimization in asset loading and caching. No critical technical debt or risks were identified, but ongoing maintenance of third-party scripts and security configurations is advised.
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.
