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

The website www.dortmund.de serves as the official city portal for Dortmund, Germany, providing comprehensive information on city administration, services, local politics, economy, leisure, tourism, and public events. It targets residents and visitors, offering a wide range of online services and up-to-date news. The site is well-branded with consistent use of the city seal and structured data, reflecting its government entity status. Technically, the site employs modern web technologies including JavaScript, privacy-enhanced YouTube embeds, and Piwik analytics, with good mobile optimization and accessibility features. Security posture is solid with HTTPS enforced and no exposed sensitive data, though explicit security headers are not evident and a cookie consent mechanism is missing, which could be improved for GDPR compliance. Overall, the domain registration and website content align well, indicating a trustworthy and legitimate government website.

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

    • 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. 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

Dortmund.de is positioned as the authoritative digital presence of the Dortmund city government, serving a large audience with essential public services and information. Its business model is non-commercial, focused on civic engagement and service delivery. The portal supports community interaction through event listings, news, and digital service access. The site demonstrates strong trust signals such as official contact details, legal entity information, and verified domain registration. The presence of multiple online services and event management indicates a mature digital ecosystem supporting city operations and citizen engagement.

Security posture

The website maintains a good security posture with HTTPS encryption and privacy-conscious embedding of third-party content (YouTube nocookie domain). No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy or X-Frame-Options suggests room for enhancement. The lack of a visible cookie consent mechanism may pose compliance risks under GDPR. Incident response and security policy information are not publicly available, which could be addressed to improve transparency and readiness.

Recommendations

  1. Implement a visible and user-friendly cookie consent banner to ensure full GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Regularly audit third-party scripts and libraries to avoid introducing vulnerabilities.
  5. Enhance accessibility features and continue optimizing mobile responsiveness to maintain excellent user experience.

Technical notes

Notes

The website uses a modern front-end stack with deferred JavaScript loading, webmanifest for PWA capabilities, and optimized font loading. It integrates Piwik (Matomo) for analytics, favoring privacy over more invasive trackers. The site is well-structured with JSON-LD for SEO and accessibility. Hosting details are not explicit, but the domain uses stable name servers. Performance is moderate with good mobile optimization. There is no explicit CMS detected, suggesting a custom or proprietary solution. Technical risks are low but could be mitigated further by adding security headers and cookie consent mechanisms.
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.
