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

7 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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 · found on this site
  • 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 Basler Münster operates as a non-profit religious and cultural institution, providing key services such as religious ceremonies, guided tours, cultural exhibitions, and community support activities. Its market position is strong as a historic landmark in Basel, serving both local and tourist audiences. The website reflects a clear business model focused on community engagement and heritage preservation. The partnership with erk-bs.ch and group booking platforms indicates a collaborative ecosystem. The absence of direct commercial activities or e-commerce suggests a focus on service and cultural promotion rather than revenue generation. Growth indicators include active event promotion and digital presence via apps for iOS and Android.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and privacy-conscious analytics configurations. The presence of a cookie consent banner aligns with GDPR requirements. However, the lack of security headers such as Content-Security-Policy and absence of a security.txt file or incident response contacts indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. The site does not appear to collect user data via forms on the homepage, reducing attack surface. Overall, the security posture is adequate for a public informational site but could benefit from enhanced security controls and transparency.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Enhance privacy compliance by detailing data retention policies and providing more comprehensive privacy notices.
  4. Consider adding contact information such as official emails and phone numbers prominently to improve user trust and support.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.

Technical notes

Notes

The website uses Joomla! CMS with a combination of jQuery and Bootstrap 4 for frontend functionality and styling. Google Analytics and Google Tag Manager are integrated for analytics and marketing purposes with IP anonymization enabled. The site is mobile optimized with responsive design and basic accessibility features. Performance is moderate, with no major issues detected in the HTML structure or resource loading. The site lacks advanced SEO optimizations but includes basic meta tags and structured navigation. No forms or user input fields were detected in the main content, limiting data collection vectors. Hosting provider details were not discernible from the provided data.
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.
