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

The website www.duesseldorf.de serves as the official city portal for the Landeshauptstadt Düsseldorf, providing comprehensive information and digital services related to city news, administration, tourism, culture, and public services. It targets residents, tourists, and businesses, positioning itself as a central government resource with a large-scale operational scope. The site leverages TYPO3 CMS and modern web technologies, ensuring a professional and accessible user experience with good mobile optimization and clear navigation. Social media integration and official branding reinforce its trustworthiness. From a technical perspective, the site uses a mature CMS platform (TYPO3), integrates analytics via eTracker, and includes accessibility tools like EyeAble. The SSL configuration is excellent, and the site is served over HTTPS with no detected blocking or WAF interference. However, some security best practices such as explicit security headers and a published vulnerability disclosure policy are absent. Security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is strong with a comprehensive GDPR-compliant privacy policy, though a cookie consent mechanism is not evident. Contact information is clearly provided with obfuscated email and phone details. WHOIS data confirms the domain's legitimacy and consistency with the official city infrastructure. Overall, the website demonstrates a high level of professionalism, security, and compliance suitable for a government entity, with minor areas for improvement in cookie consent and security policy transparency.

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

The Landeshauptstadt Düsseldorf website is a key digital asset for the city government, serving multiple stakeholder groups including citizens, tourists, and businesses. Its market position is that of an authoritative government portal, offering a broad range of services from news updates to digital administrative processes. The business model is non-commercial, focusing on public service delivery and information dissemination. The site’s partnership ecosystem includes related municipal services and tourism platforms. Growth indicators include active content updates and integration of digital services such as online applications for the Ausländerbehörde. Strategic observations highlight the importance of maintaining high accessibility and security standards to serve a diverse audience effectively.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no visible exposure of sensitive information. The use of obfuscated email addresses and limited form data collection reduces attack surface. However, the absence of explicit security headers like Content-Security-Policy and lack of published incident response or vulnerability disclosure policies indicate room for enhancement. Analytics usage via eTracker is moderate and privacy compliant. No signs of malware, phishing, or other critical vulnerabilities were detected. Incident response readiness and security culture indicators are not publicly documented, which is common for government sites but could be improved for transparency.

Recommendations

  1. Implement a visible cookie consent banner to comply fully with EU cookie laws and enhance user privacy transparency.
  2. Add and publish a security policy and incident response contact information to improve trust and preparedness.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the site against common web attacks.
  4. Create and publish a vulnerability disclosure or security.txt file to encourage responsible reporting and improve security posture.
  5. Continue to maintain and update accessibility features and ensure mobile optimization remains current with evolving standards.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used open-source content management system, supported by Bootstrap and jQuery for responsive design and interactivity. The integration of eTracker analytics and EyeAble accessibility tools demonstrates a commitment to user experience and data-driven insights. Performance is moderate with standard web assets and image optimizations. The site uses modern meta tags for SEO and Open Graph for social media sharing. No critical technical debt or deprecated technologies were detected. Hosting details are not explicitly stated but WHOIS data indicates stable German infrastructure. Opportunities exist to enhance security headers and implement modern privacy consent frameworks.
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.
