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

The website www.dorsten.de serves as the official municipal portal for the city of Dorsten in Germany, providing comprehensive information and services related to local government, culture, education, social welfare, and economic development. It targets residents, visitors, and businesses within the city, offering a broad range of public services and community resources. The site is built on a modern open-source technology stack, primarily using the Neos CMS and Flow PHP framework, hosted on reputable infrastructure provided by Hetzner. The website demonstrates good digital maturity with responsive design, clear navigation, and integration of privacy-conscious analytics via Matomo. Security posture is solid with HTTPS enforced and no visible vulnerabilities, though there is room for improvement in security headers and published security policies. Privacy compliance is moderate, with a cookie consent mechanism present but lacking an explicit privacy policy and terms of service. Overall, the site is professional, trustworthy, and safe for general audiences, reflecting the standards expected of a government entity.

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

3 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 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

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

Dorsten's municipal website positions itself as a central hub for local governance and community engagement, offering services such as citizen support, digital service portals, cultural programming, and urban planning information. The business model is that of a government entity focused on public service rather than commercial revenue. The site links to partner domains related to regional planning, tourism, and social services, indicating a collaborative ecosystem. The absence of commercial advertising and affiliate programs aligns with its public sector nature. The website's comprehensive content and structured navigation support effective communication with diverse stakeholder groups including families, seniors, businesses, and tourists. Growth indicators include digital service expansion and integration of modern web technologies. Strategic observations suggest opportunities to enhance transparency and trust through published privacy and security policies.

Security posture

The website exhibits a mature security posture with HTTPS enabled and use of secure forms. The presence of Matomo analytics reflects a privacy-aware approach to user tracking. However, the site lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. No incident response or vulnerability disclosure information is published, which is a gap in security culture and readiness. No exposed sensitive data or vulnerable libraries were detected in the provided content. The overall security score is good but could be improved by adopting best practices in security headers, publishing security policies, and establishing clear incident response channels. Compliance with GDPR is implied but not explicitly documented, representing a compliance gap.

Recommendations

  1. Publish a comprehensive privacy policy detailing data collection, processing, and user rights to improve GDPR compliance.
  2. Implement and disclose a formal security policy and incident response contact information to enhance security transparency.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen defense against common web attacks.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance contact information visibility including official emails and phone numbers to improve user trust and support.

Technical notes

Notes

The website is built on the Neos CMS platform leveraging the Flow PHP framework, indicating a modern and flexible content management infrastructure. The use of external CSS and JavaScript libraries such as FontAwesome, Leaflet, and jQuery supports rich UI components and mapping features. Hosting is provided by Hetzner, a reputable German hosting provider, ensuring reliable infrastructure. Performance is moderate with room for optimization, particularly in asset loading and caching strategies. The site is mobile-optimized and accessible, with features like skip links and contrast toggles enhancing usability. SEO is well addressed with meta tags, canonical links, and structured data in JSON-LD format. Technical risks are minimal but could be mitigated further by updating security headers and ensuring continuous monitoring of dependencies.
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.
