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

The website 'Offene Daten Wuppertal' is an official open data portal operated by the city government of Wuppertal, Germany, and hosted by the city of Cologne. It provides public access to a wide range of datasets across multiple categories such as population, geography, infrastructure, health, and environment. The platform is built on Drupal 7 and DKAN, leveraging open source technologies to deliver structured and accessible data to citizens, developers, and researchers. The site features a dataset search, categorized data listings, blog entries, and social media integration, supporting community engagement and transparency. Technically, the site uses a mature but somewhat dated CMS (Drupal 7) with Bootstrap for responsive design and Piwik (Matomo) for analytics. The performance is moderate with good mobile optimization and basic accessibility features. Security posture is solid with HTTPS enforced and no visible sensitive data exposure, though it lacks some modern security headers and explicit security policies. Privacy compliance is partial, with privacy and terms pages present but no visible cookie consent mechanism. Overall, the website demonstrates a high level of trustworthiness and professionalism consistent with a government entity. It effectively serves its purpose as an open data platform but could improve in areas of privacy compliance, security best practices, and explicit contact information to enhance user trust and regulatory adherence.

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.

Priority findings

9 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

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 portal positions itself as a key local government service providing open data to the public, supporting transparency and civic engagement. Its competitive advantage lies in its official backing and integration with the DKAN platform, enabling structured data publication and community interaction. The business model is non-commercial, focused on public service and data dissemination. Target customers include citizens, developers, researchers, and municipal stakeholders. The partnership with Stadt Köln for hosting and platform operation strengthens its operational reliability. Growth indicators include regular dataset updates and active blog content. Strategic observations suggest opportunities to expand privacy and security features and improve direct contact channels to foster greater user confidence.

Security posture

The website maintains a good security baseline with HTTPS and secure form handling via Drupal. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security policy or incident response contact reduces transparency in security management. GDPR compliance is partially addressed but could be improved with cookie consent mechanisms. Overall, the security maturity is moderate, suitable for a government open data portal but with room for enhancement in security best practices and incident readiness.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and improve privacy transparency.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Publish a dedicated security policy and incident response contact information to improve trust and readiness.
  4. Update Drupal core and third-party libraries to the latest supported versions to reduce vulnerability risks.
  5. Provide explicit contact emails and phone numbers for user support and inquiries to enhance communication.

Technical notes

Notes

The website is built on Drupal 7 with the DKAN open data platform, using jQuery 1.10 and Bootstrap for frontend responsiveness. It integrates Piwik (Matomo) for analytics and Twitter widgets for social media. Hosting appears to be managed by Stadt Köln, indicated by nameservers and analytics domains. The site loads multiple CSS and JS assets, some conditional for older IE versions, indicating legacy support. Performance is moderate with room for optimization. Accessibility is basic but functional. SEO is basic with meta tags and structured vocabularies but no JSON-LD or Open Graph tags detected. The technical stack is stable but could benefit from modernization and enhanced security configurations.
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.
