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

Mängelmelder.de is a German nationwide platform enabling citizens to report public infrastructure issues directly to their local municipalities. The platform facilitates transparent tracking of reported issues via web and mobile apps, promoting civic engagement and municipal responsiveness. The service operates on a voluntary basis by municipalities and is supported by the company wer denkt was GmbH. The website is professionally designed, mobile-optimized, and integrates interactive mapping and multimedia content to enhance user experience. Technically, the site leverages modern web technologies including Vue.js, OpenLayers for mapping, jQuery, and FontAwesome icons. Hosting is provided via Amazon AWS infrastructure, ensuring reliable performance and scalability. Analytics are handled through Matomo with a cookie consent mechanism respecting user privacy. The site demonstrates good SEO and accessibility practices, though some accessibility features could be improved. From a security perspective, the site enforces HTTPS and employs cookie consent for tracking scripts. However, it lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The WHOIS data is consistent and transparent, with no privacy protection or suspicious patterns, indicating a legitimate and trustworthy domain. Overall, Mängelmelder.de presents a solid digital presence with a clear civic mission, good technical implementation, and a moderate to strong security posture. Enhancements in security policy transparency and accessibility could further strengthen trust and compliance.

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. 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 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

Mängelmelder.de occupies a niche in the government and non-profit sector, focusing on citizen engagement and municipal service improvement. Its competitive advantage lies in its nationwide reach, integration with local governments, and multi-platform accessibility. The business model centers on providing a free or commissioned platform service to municipalities, supported by mobile apps and web interfaces. Revenue streams likely include municipal contracts and platform licensing. The target customers are citizens and local governments in Germany. The company maintains partnerships with related platforms and promotes its service through reference lists and awards. Growth indicators include a large volume of reported issues and active user engagement. The ecosystem includes related domains such as werdenktwas.de and mängelmelderpro.de, indicating a broader service network.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, cookie consent for analytics, and no visible exposure of sensitive data. The use of Matomo analytics with opt-in respects privacy regulations. However, the absence of security headers like Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No published security or incident response policies limit transparency for security incidents. There is no vulnerability disclosure or security.txt file, which could hinder coordinated vulnerability reporting. Overall, the security maturity is good but could be improved by adopting additional HTTP security headers and publishing formal security policies.

Recommendations

  1. Implement HTTP security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to comply with WCAG standards and improve user experience for all visitors.
  5. Regularly review and update cookie consent mechanisms to ensure ongoing GDPR compliance and user privacy.

Technical notes

Notes

The website is built on a custom CMS platform provided by werdenktwas.de, utilizing modern JavaScript frameworks like Vue.js and mapping libraries such as OpenLayers 6. The tech stack includes jQuery 3.6.0 and FontAwesome for UI elements. Hosting is on Amazon AWS, indicated by the DNS servers. Performance is moderate with asynchronous loading of analytics scripts and optimized CSS. The site is mobile-optimized with responsive design and accessible navigation. SEO is supported by meta tags, Open Graph tags, and structured navigation. Technical risks are minimal, but the lack of security headers and formal security policies represent areas for modernization and risk mitigation.
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.
