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

Visit Düsseldorf is the official tourism website promoting the city of Düsseldorf, Germany. It provides comprehensive information about sightseeing, events, city tours, shopping, culture, and accommodation options. The website targets tourists and visitors seeking to explore Düsseldorf and offers services such as hotel bookings, event calendars, and the DüsseldorfCard. The site is well-branded and professionally designed, reflecting its role as a key city tourism portal. Technically, the website is built on the Neos CMS platform using the Flow PHP framework, enhanced with modern JavaScript libraries and third-party widgets for events and accessibility. It leverages Cloudflare for DNS and likely CDN services, employs Google Tag Manager for analytics, and uses Usercentrics for consent management, indicating a mature digital infrastructure. From a security perspective, the site enforces HTTPS and uses bot protection via hCaptcha. While basic security best practices are observed, explicit security headers and published security policies are missing. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is moderate due to the absence of a visible privacy policy and terms of service. Overall, the website presents a low-risk profile with strong business credibility and technical implementation. Strategic improvements include publishing comprehensive privacy and security policies, adding vulnerability disclosure information, and enhancing security headers to further strengthen trust and compliance.

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. 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 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

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 serves as a central hub for Düsseldorf's tourism sector, positioning itself as the authoritative source for visitors. Its business model revolves around promoting city attractions and facilitating bookings for tours, events, and accommodations. Revenue streams likely include ticket sales for city cards and tours, as well as partnerships with local businesses. The target audience includes leisure tourists, cultural enthusiasts, and event attendees. The presence of partner domains like mein.toubiz.de and the Düsseldorf-Shop indicates a collaborative ecosystem supporting tourism services. The site demonstrates strong market positioning with consistent branding and comprehensive content, supporting growth and visitor engagement.

Security posture

The security posture of the website is solid with HTTPS enforced and integration of bot protection mechanisms. Consent management via Usercentrics aligns with GDPR requirements. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security or incident response policies represent gaps. No vulnerabilities or sensitive data exposures were found in the HTML content. The site does not provide a vulnerability disclosure or security.txt file, limiting transparency for security researchers. Overall, the security maturity is good but could be enhanced by formalizing security policies and improving HTTP header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve privacy compliance and user trust.
  2. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Add explicit incident response contact information to demonstrate readiness and transparency.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website uses a modern technology stack centered on Neos CMS and the Flow PHP framework, supported by JavaScript widgets for enhanced user experience. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized with good accessibility features, including integration with eyeAble accessibility tools. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. Performance is moderate, with video and image assets optimized for various screen sizes. The technical implementation is robust, though opportunities exist to improve security headers and formalize privacy and security documentation.
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.
