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

KölnTourismus GmbH operates as the official tourism organization for the city of Cologne, Germany, providing comprehensive visitor information, event promotion, and cultural guidance. The website serves tourists and visitors with relevant content about sightseeing, museums, and local events, positioning itself as a trusted and authoritative source for tourism in the region. The business model focuses on promoting the city's attractions and facilitating visitor engagement. Technically, the website is built on TYPO3 CMS, a robust and widely used content management system, hosted on Schlund Technologies infrastructure. The site demonstrates good mobile optimization, accessibility, and SEO practices. Cookie consent is managed via Cookiebot, indicating compliance with GDPR requirements. Performance is moderate, with room for optimization. From a security perspective, the site enforces HTTPS and uses a consent management platform, but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or suspicious content were detected. The domain registration data aligns well with the website's claims, supporting legitimacy. Overall, the website presents a professional and trustworthy front for KölnTourismus, with minor gaps in privacy and security documentation. Strategic improvements in security headers, privacy policy publication, and incident response transparency would enhance the site's security posture and compliance standing.

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

5 findings rated critical or high. Fix these first.

  1. 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';…
  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

KölnTourismus GmbH holds a strong market position as the official tourism body for Cologne, leveraging city branding and cultural assets to attract visitors. Its competitive advantage lies in official endorsement and comprehensive local knowledge. The business model is centered on tourism promotion rather than direct sales, likely funded by municipal or regional support. Target customers include domestic and international tourists interested in cultural and event experiences. The company maintains an active social media presence, enhancing engagement and outreach. Growth indicators include multilingual site versions and event-driven content. Partnerships with cultural institutions and media channels support its ecosystem. Operationally, the organization focuses on content quality and visitor services rather than e-commerce.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and cookie consent mechanisms in place. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options represents a gap in defense-in-depth strategies. No incident response or vulnerability disclosure policies are published, which could delay response to security incidents. Data protection practices appear basic, with no visible sensitive data exposure or vulnerable libraries detected. The site lacks dedicated security contact channels, limiting transparency. Compliance with GDPR is partially indicated via cookie consent but lacks a formal privacy policy. Overall, the security posture is adequate for a public informational site but could be improved to meet higher standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy to enhance GDPR compliance and user trust.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to improve protection against common web attacks.
  3. Establish and publicize an incident response and vulnerability disclosure policy with dedicated contact channels.
  4. Regularly audit and update third-party libraries and CMS components to mitigate vulnerabilities.
  5. Enhance transparency by providing clear data retention policies and cookie usage explanations.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible platform suitable for content-rich sites. Hosting is provided by Schlund Technologies, a reputable provider. The site uses modern CSS and responsive design techniques, ensuring good mobile usability and accessibility. Cookiebot integration supports GDPR compliance through consent management. Performance is moderate, with potential for optimization in asset delivery and caching. No deprecated or vulnerable libraries were detected in the provided data. The site lacks some advanced SEO and security technical implementations, such as structured security headers and detailed metadata for privacy and terms. Overall, the technical infrastructure is solid but could benefit from modernization in security and privacy features.
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.
