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

Wasserverband Nettelnburg is a public law entity responsible for maintaining the drainage ditches in the Nettelnburg district of Hamburg, Germany. The website serves as an official information portal providing details about the association's tasks, legal framework, events, and member responsibilities. It targets local residents and members of the water association, focusing on community engagement and regulatory compliance. The business operates in the government sector with a small organizational size and a history dating back to the 1920s. Technically, the website is built on WordPress using the Avada theme and employs the Complianz GDPR plugin for cookie consent management. The site is moderately optimized for performance and mobile devices, with basic accessibility and good SEO practices. No advanced analytics or marketing tools are detected, indicating a focus on privacy and minimal user tracking. From a security perspective, the site uses HTTPS and has implemented cookie consent mechanisms, but lacks visible security headers and explicit security policies. No vulnerabilities or exposed sensitive data were found in the content. However, the absence of WHOIS registration data for the domain raises concerns about domain legitimacy, although the website content itself appears professional and trustworthy. Overall, the website presents a solid digital presence for a local government entity with good content quality and privacy compliance. The main risk lies in the missing WHOIS data, which should be investigated further to confirm domain ownership and registration legitimacy.

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. 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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 Wasserverband Nettelnburg operates as a niche local government organization focused on water management and drainage maintenance. Its competitive advantage lies in its official status and community integration within Hamburg's Bergedorf district. The business model is service-oriented, relying on member contributions and regulatory enforcement. The website supports transparency and communication with members through detailed legal documents, event announcements, and operational guidelines. Growth indicators are limited due to the nature of the entity, but the presence of detailed project pages and historical archives suggests active community engagement. The partnership ecosystem includes local service providers and possibly municipal authorities, although no explicit partners are listed on the site.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR cookie consent implemented. There is no evidence of advanced security headers or incident response policies publicly available. The lack of WHOIS data is a notable gap in domain trust verification. No vulnerable libraries or exposed credentials were detected. Compliance with GDPR is indicated by the cookie banner and privacy policy, but no explicit certifications or security frameworks are mentioned. Incident response readiness and security culture indicators are not visible on the site. Overall, the security posture is adequate for a small government website but could be improved with enhanced header policies and public security documentation.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish explicit security and incident response policies to enhance transparency and preparedness.
  3. Investigate and resolve the missing WHOIS registration data to improve domain legitimacy and trust.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Consider adding a dedicated data protection officer contact and vulnerability disclosure policy.

Technical notes

Notes

The website is built on a modern CMS platform (WordPress) with a popular theme (Avada) and uses jQuery for client-side scripting. The Complianz GDPR plugin manages cookie consent, indicating compliance with privacy regulations. The site loads external resources from trusted domains and uses HTTPS, ensuring encrypted communication. Performance is moderate with no major issues detected, and mobile optimization is good. Accessibility features are basic but present. SEO is supported by proper meta tags and structured navigation. There is no evidence of advanced analytics or marketing tools, which reduces tracking risks but limits marketing insights. Hosting provider details are not disclosed in the content.
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.
