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

The Regenkompass website is a public sector initiative managed by StEB Köln, focusing on sustainable rainwater management and climate adaptation strategies for the city of Cologne. It serves as an informational platform targeting residents and stakeholders interested in environmental urban planning, offering detailed content on green roofs, facade greening, de-sealing, and rainwater usage. The site positions itself as a local leader in promoting sustainable urban water management practices. Technically, the website is built on WordPress with a modern tech stack including Yoast SEO, jQuery, and Usercentrics for cookie consent, complemented by Google Analytics 4 for user tracking. The site demonstrates good mobile optimization, SEO practices, and moderate performance. Hosting appears to be with Your-Server.de, a known German hosting provider. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms, with no visible vulnerabilities or exposed sensitive data. However, security headers are not explicitly detected, and no incident response or vulnerability disclosure information is provided, indicating room for improvement in security transparency. Overall, the website is trustworthy, professionally maintained, and compliant with GDPR requirements. The domain registration data is minimal but consistent with the official nature of the site. Strategic recommendations include enhancing security headers, publishing incident response contacts, and expanding transparency on security policies.

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

8 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

      • 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';…

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

Regenkompass operates as a government-backed environmental information platform under StEB Köln, targeting urban residents and stakeholders in Cologne. Its competitive advantage lies in its official status and integration with city initiatives, providing authoritative content on sustainable rainwater management. The business model is informational and public service-oriented, with no direct revenue streams evident. The partnership ecosystem includes the City of Cologne and environmental organizations. Growth indicators include active event listings and updated content. The platform supports Cologne's strategic climate adaptation goals and fosters community engagement through social media channels.

Security posture

The website exhibits a mature security posture with HTTPS enforced and GDPR-compliant cookie consent implemented via Usercentrics. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and lack of published incident response or vulnerability disclosure policies represent compliance gaps. The site does not expose forms with sensitive inputs beyond standard contact forms. Overall, the security culture appears adequate for a public informational site but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish an incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ email).
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is powered by WordPress 6.8.2 with a modern and well-maintained theme and plugins such as Yoast SEO for search optimization. It uses jQuery and modern JavaScript modules for UI components like photo galleries and carousels. Cookie consent is managed by Usercentrics, ensuring GDPR compliance. Google Analytics 4 is integrated for user behavior tracking. Hosting is likely provided by Your-Server.de based on nameserver data. Performance is moderate with asynchronous script loading and responsive design. Technical debt appears low, but security header implementation is lacking, representing a modernization opportunity.
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.
