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

4 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

  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 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. 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

Castrop-Rauxel's website positions itself as a central hub for municipal services and citizen engagement. The business model is government service provision with a focus on transparency, accessibility, and digital transformation. The site links to partner domains including service portals, geoportals, and utility companies, indicating a collaborative ecosystem. The target audience includes local residents, families, businesses, and tourists. The site demonstrates good content quality and navigation, supporting effective communication and service delivery. Growth indicators include digital initiatives like the CAS-App and active event promotion. The partnership ecosystem is robust with multiple official linked domains.

Security posture

The website employs HTTPS and a cookie consent mechanism, reflecting baseline security and privacy practices. The use of Matomo analytics with DoNotTrack enabled suggests respect for user privacy. However, no explicit security headers or published security policies were found, and no incident response or vulnerability disclosure information is available. The absence of a security.txt file and direct contact channels for security incidents indicates room for improvement in security transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is moderate but could be enhanced with additional security controls and disclosures.

Recommendations

  1. Publish a clear and accessible privacy policy and terms of service pages to improve compliance and user trust.
  2. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file and provide explicit incident response contact information to enhance security transparency.
  4. Consider publishing a vulnerability disclosure policy to encourage responsible reporting of security issues.
  5. Regularly audit and update third-party libraries and CMS components to mitigate potential vulnerabilities.

The website is built on Drupal 10, leveraging Bootstrap 5 for responsive design and jQuery UI for UI components. It uses Klaro for cookie consent management and Slick Carousel for interactive content display. The hosting is managed via INWX nameservers, indicating a professional domain management setup. The site demonstrates good mobile optimization and accessibility features, with structured navigation and search functionality. Performance is moderate, with no major issues detected. SEO is supported by canonical and shortlink meta tags. The technical stack is modern and appropriate for a government website, though security header implementation could be improved.
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.
