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

Bistum Münster is the second largest Catholic diocese in Germany, serving nearly two million Catholics with a broad range of spiritual, educational, and social services. The website reflects a mature digital presence built on TYPO3 CMS, featuring comprehensive content about church activities, pastoral care, education, and community support. The site is well-structured, mobile-optimized, and integrates social media channels to engage its audience effectively. GDPR and cookie compliance are well addressed, enhancing user trust. Technically, the site uses modern frontend libraries and frameworks such as Foundation, jQuery, and Slick Carousel, ensuring a responsive and accessible user experience. Hosting appears to be on a reputable German research network, supporting reliability and security. However, the site lacks explicit security policies and incident response contacts, which could be improved to strengthen its security posture. Security-wise, HTTPS is enforced, and no obvious vulnerabilities or exposed sensitive data were detected. The site uses some third-party scripts but does not appear to employ extensive tracking or advertising networks, aligning with its non-profit religious mission. The WHOIS data is limited but consistent with the organization's identity, supporting legitimacy. Overall, Bistum Münster's website is a professional, trustworthy, and content-rich platform that effectively serves its community and stakeholders. Strategic improvements in security transparency and policy publication would further enhance its credibility and resilience.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

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 Bistum Münster operates as a large non-profit religious organization with a strong regional presence in Germany. Its market position as the second largest diocese in the country gives it significant influence in religious, educational, and social sectors. The business model focuses on community service, pastoral care, and education rather than commercial revenue. Key services include sacramental guidance, educational institutions, social support, and prevention programs. The organization maintains partnerships with related church and social service entities, enhancing its service ecosystem. The website's comprehensive content and clear navigation support engagement with diverse audience segments including youth, families, seniors, and people with disabilities. Growth indicators include active event calendars and ongoing structural change processes. The partnership ecosystem includes Caritas, church seminaries, and job market platforms, reflecting a well-integrated operational network.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and no visible exposure of sensitive data. The use of secure external links and minimal tracking scripts aligns with privacy best practices. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in security transparency and readiness. No critical vulnerabilities or outdated libraries were detected in the HTML content. The site would benefit from implementing security headers such as Content-Security-Policy and publishing a security.txt file to improve incident response and vulnerability management. GDPR compliance is well addressed, but further enhancements in security communication would strengthen the overall posture. The current security score is good but leaves room for improvement in policy visibility and proactive security culture.

Recommendations

  1. Publish a dedicated security policy page and provide clear incident response contact information.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency around data protection officer contact details and compliance measures.

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 frontend leverages modern JavaScript libraries such as jQuery, Foundation Framework, Slick Carousel, and Plyr for multimedia, ensuring a responsive and interactive user experience. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Hosting appears to be managed via a German academic/research network (DFN), which suggests reliable and secure infrastructure. Performance is moderate, with potential for optimization in script loading and caching. The technical stack is modern but could benefit from enhanced security configurations and performance tuning to reduce load times and improve user experience further.
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.
