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

The Allgemeiner Deutscher Fahrrad-Club e. V. (ADFC) operates as a large non-profit organization advocating for cycling and sustainable transportation in Germany. With over 240,000 members, it holds a strong market position as the world's largest cycling interest group. The website serves as a comprehensive platform offering membership services, advocacy information, event announcements, and educational content focused on cycling safety and infrastructure. The target audience includes cyclists, policymakers, and environmentally conscious individuals in Germany. Technically, the website is built on TYPO3 CMS, leveraging modern web technologies including Matomo analytics and Facebook Pixel for tracking with user consent. The site is well-optimized for mobile devices, accessible, and SEO-friendly, reflecting a mature digital infrastructure. The presence of cookie consent mechanisms and a detailed privacy policy indicates good privacy compliance. From a security perspective, the site uses HTTPS with a good SSL configuration and implements cookie consent for tracking scripts. However, explicit security headers like Content-Security-Policy are not evident, and no formal security policy or incident response contacts are published. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the website is professional, trustworthy, and well-maintained, supporting the organization's mission effectively. The domain WHOIS data is minimal but consistent with the organization's legitimacy. Strategic recommendations include enhancing security headers, publishing a security policy, and considering a vulnerability disclosure program to further strengthen security 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

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 advocacy group in the transportation sector, focusing on cycling promotion and infrastructure improvement in Germany. Its competitive advantage lies in its large membership base and comprehensive service offerings including roadside assistance and educational resources. Revenue streams likely include membership fees, donations, and possibly grants. The organization targets cyclists of all ages, policymakers, and environmentally conscious citizens. Growth indicators include active event scheduling and campaigns. The partnership ecosystem includes collaborations with local groups and possibly insurance and mobility service providers. The website reflects a mature operation with consistent branding and professional content.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and cookie consent mechanisms in place. The use of Matomo and Facebook Pixel is managed with user consent, aligning with privacy regulations. However, the absence of explicit security headers and a published security or incident response policy indicates room for improvement. No critical vulnerabilities or exposed sensitive data were found. Compliance with GDPR is supported by a comprehensive privacy policy and cookie banner. Incident response readiness and vulnerability disclosure mechanisms are not evident, which could be enhanced to improve security culture and transparency.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a formal security policy and provide clear incident response contact information to improve transparency and readiness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to minimize risks from external dependencies.
  5. Enhance server-side security configurations and conduct periodic penetration testing to identify and remediate potential weaknesses.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable and scalable infrastructure. The integration of Matomo analytics and Facebook Pixel shows a balanced approach to data analytics with privacy considerations. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and structured navigation. Performance is moderate, with asynchronous loading of scripts to improve user experience. Technical debt appears low, but opportunities exist to modernize security headers and enhance incident response capabilities. Overall, the technical implementation supports the organization's operational needs effectively.
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.
