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

6 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';…

  3. 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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention mainziel.de, from OffSeq Breach.

No leaked records found

Breach holds no records for mainziel.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website targets a broad audience including residents, commuters, and visitors of Frankfurt am Main, offering free access to multimodal mobility information. Its business model is public service without monetization. The platform integrates various transport modes and services, positioning itself as the official city traffic information portal. Partnerships with city services and event venues like Deutsche Bank Park are evident. The site demonstrates a mature digital presence with ongoing feature enhancements such as live public transport data and bicycle route planners. The lack of explicit business registration details or contact emails suggests a government-operated service rather than a commercial entity.

Security posture

Security measures include HTTPS enforcement, privacy-conscious analytics configuration, and cookie consent management. However, the absence of security headers like Content-Security-Policy and no visible security or incident response policies indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The site does not provide a vulnerability disclosure or security.txt file, which could enhance transparency and incident handling. Overall, the security posture is adequate for a public informational site but could be strengthened to align with best practices and compliance requirements.

Recommendations

  1. Publish a clear privacy policy and terms of service to improve transparency and compliance.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security policy page and incident response contact information to enhance trust and readiness.
  4. Consider publishing a security.txt file or vulnerability disclosure to facilitate responsible reporting.
  5. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.

Technical notes

Notes

The website is powered by TYPO3 CMS with Bootstrap for responsive design and uses jQuery 3.7.1, OpenLayers for mapping, and proj4js for geospatial calculations. Matomo analytics is configured with privacy settings, and Cookiebot manages cookie consent. The site loads multiple CSS and JS assets, some asynchronously, indicating a modern approach to performance. Mobile optimization and accessibility features such as skip links and language navigation are present. The site performance is moderate, with potential for optimization in script loading and caching. Hosting appears municipal, consistent with the domain's name servers. Overall, the technical infrastructure supports a robust and user-friendly public service platform.
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.
