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

The website 'Gottesdienste im Bistum Aachen' serves as an official platform for the Diocese of Aachen, Germany, providing comprehensive information about church services within the diocese. It offers users the ability to search for services by location and date, focusing on the upcoming two weeks, and includes additional information about parishes and church buildings. The site is clearly targeted at residents and visitors interested in religious services in the region, positioning itself as a trusted community resource within the non-profit religious sector. Technically, the website is built on the OpenCms content management system and employs modern JavaScript libraries such as Slick Slider for UI elements and Matomo for privacy-conscious analytics. The site is hosted on domains associated with the Diocese of Aachen, ensuring alignment between hosting and organizational identity. Performance is moderate with good mobile optimization and basic accessibility features. SEO practices are adequately implemented with proper meta tags and structured data. From a security perspective, the site enforces HTTPS and includes a GDPR-compliant cookie consent banner. However, it lacks explicit security headers and does not provide visible security policies or incident response information. No vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns well with the website's claims, showing consistent registration and no privacy protection, which is appropriate for this type of organization. Overall, the website demonstrates a solid security posture and good privacy compliance, with a trustworthy and professional presentation. Strategic improvements could include adding security headers, publishing a security policy, and providing incident response contacts to enhance transparency and security readiness.

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.

Priority findings

6 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Security headers

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 Diocese of Aachen operates this website as a key digital touchpoint to facilitate community engagement and religious participation. Its market position is that of an official diocesan service, providing authoritative and localized information on church services. The business model is informational and service-oriented, focusing on community support rather than commercial revenue. The site leverages partnerships with the KirchenZeitung newspaper and Einhard Verlag publishing house, enhancing its content and outreach. The target audience includes local parishioners, visitors, and religious community members. The platform's growth potential lies in expanding digital services and improving user engagement through mobile apps and enhanced search capabilities.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and GDPR-compliant cookie management. The use of Matomo analytics reflects a privacy-conscious approach to user tracking. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure mechanisms are publicly available, which could hinder rapid response to security issues. The WHOIS data is transparent and consistent, supporting trustworthiness. Overall, the site is secure for its purpose but would benefit from enhanced security policies and technical controls.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to meet higher standards for users with disabilities.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on the OpenCms platform, leveraging JavaScript libraries such as Slick Slider for interactive UI components and Matomo for analytics. Hosting is managed via domains associated with the Diocese of Aachen, indicating organizational control over infrastructure. The site uses responsive design techniques and lazy loading for images, contributing to good mobile optimization and performance. Meta tags and JSON-LD structured data are properly implemented, supporting SEO. However, the absence of explicit security headers and limited accessibility features suggest areas for technical enhancement. Overall, the infrastructure is stable and modern but could benefit from security and accessibility improvements.
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.
