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

OpenData ÖPNV Deutschland is a German initiative providing open public transport data to developers and mobility stakeholders. The platform offers datasets including stops, schedules, and real-time information accessible via APIs to foster innovation in public transport applications. The website is built on TYPO3 CMS with a modern responsive design and integrates cookie consent mechanisms compliant with GDPR. Security posture is solid with HTTPS enforced and secure login forms, though some security headers and explicit policies could be improved. Overall, the platform demonstrates a mature digital infrastructure supporting its mission to enhance mobility through open data.

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

5 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. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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.

Technical appendix

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

Business context

Business profile

The platform occupies a strategic position in the German public transport sector as a key open data provider. Its business model focuses on enabling third-party developers and startups to leverage transport data for innovative solutions. Partnerships with recognized transport organizations like DELFI strengthen its ecosystem. The absence of direct contact details on the homepage suggests a focus on self-service and developer engagement. The platform's content and showcases indicate active community involvement and continuous updates, supporting growth and relevance in the mobility data market.

Security posture

The website enforces HTTPS and uses a reputable cookie consent tool (Cookiebot) to manage user privacy. Login forms use secure POST methods, and no sensitive data is exposed in the HTML. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published incident response or vulnerability disclosure policies indicate areas for improvement. No vulnerabilities or suspicious patterns were detected. The security score is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page including incident response contacts and procedures.
  3. Add a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance contact information availability for security and general inquiries to improve trust and support.

Technical notes

Notes

The website leverages TYPO3 CMS and Bootstrap framework, ensuring responsive and accessible design. Integration of Google Tag Manager and Cookiebot indicates modern analytics and privacy compliance practices. Performance is moderate with optimized images and lazy loading. The site structure supports clear navigation and SEO best practices. Technical debt appears low, but opportunities exist to improve security headers and provide more detailed hosting and infrastructure transparency. Overall, the technical implementation supports the business goals effectively.
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.
