Priority findings

1 finding rated critical or high in the checks that completed. Fix these first.

  1. 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

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

  • Security headers: did not complete in this scan.
  • Email security: did not complete in this scan.
  • Network security: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

ZdK occupies a central role in the German Catholic community, acting as a liaison between lay representatives and broader church and societal institutions. Its business model is non-profit and advocacy-focused, relying on events, publications, and digital content to engage its audience. The organization leverages multiple social media platforms to extend its reach and maintains a newsletter and podcast to deepen engagement. While no direct revenue streams are visible, the organization's influence and network position it as a key stakeholder in religious and social discourse in Germany. The website's structured content and clear navigation support its role as an authoritative source for Catholic lay perspectives.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and a cookie consent mechanism that aligns with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, or vulnerability disclosure mechanisms indicates areas for enhancement. The site does not currently publish security headers such as Content Security Policy or HSTS, which could further harden its defenses. Overall, the security measures are adequate for the organization's profile but could be improved to meet higher standards and increase user trust.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page and provide clear incident response contact information.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance with WCAG standards.
  5. Regularly audit third-party scripts and analytics tools for security and privacy compliance.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, ensuring a stable and scalable platform. The use of Bootstrap classes indicates a responsive design approach, providing good mobile optimization. Matomo analytics is used for privacy-conscious visitor tracking. The site loads CSS and JS assets in compressed and merged forms, indicating performance optimization efforts. However, no explicit hosting provider information was found. The site performs moderately well with good SEO meta tags and structured navigation. Opportunities exist to improve accessibility and implement modern security headers to reduce technical risks.
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.
