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

6 findings rated critical or high. Fix these first.

  1. 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

  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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

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 website operates within the transportation sector, specifically public transit information services. It is closely affiliated with Stadtwerke Münster, a municipal utility provider, indicating a stable and official market position. The business model focuses on providing free access to transit data and journey planning tools, likely funded as part of public services. The target audience includes local commuters, tourists, and mobility users in Münster. The partnership ecosystem includes data providers and mapping services. The site shows indicators of moderate digital maturity with modern frameworks and analytics integration, supporting growth and user engagement.

Security posture

The website demonstrates a good security baseline with enforced HTTPS, presence of key security headers, and CSRF token implementation. No sensitive data is exposed in the HTML content. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure reduces transparency and preparedness perception. The site lacks a cookie consent mechanism, which is a GDPR compliance gap. No known vulnerabilities or outdated libraries were detected in the provided content. Overall, the security posture is adequate for a public information site but could be improved with formal policies and disclosures.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR cookie regulations.
  2. Publish a comprehensive security policy and 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 and user inclusivity.
  5. Improve SEO metadata and structured data to boost search engine visibility.

Technical notes

Notes

The website uses AngularJS framework combined with Leaflet for interactive mapping, supported by Bootstrap and FontAwesome for UI components and icons. Hosting appears to be managed via your-server.de and second-ns.de nameservers. Performance is moderate with multiple map tile requests and dynamic content loading. The site is mobile optimized and includes accessibility basics but could improve ARIA roles and keyboard navigation. Google Analytics and Tag Manager are integrated for user tracking. No CMS is explicitly detected, suggesting a custom or framework-based implementation. Technical risks are low but modernization opportunities exist by upgrading AngularJS to a newer framework version.
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.
