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

S-Bahn Berlin GmbH operates the official website for Berlin's urban rail transit system, providing comprehensive services including timetable information, ticket sales, route planning, and customer support. The website targets commuters, tourists, and residents in Berlin, offering multilingual content and extensive travel-related resources. The company holds a strong market position as a key public transportation provider in Germany's capital. Technically, the website is built on TYPO3 CMS and integrates modern tools such as Matomo for analytics and Usercentrics for consent management, reflecting a mature digital infrastructure. The site is mobile-optimized, accessible, and SEO-friendly, ensuring a positive user experience across devices. From a security perspective, the site enforces HTTPS, employs domain transfer locks, and uses consent management for cookies, indicating good security hygiene. However, DNSSEC is not enabled, and no explicit security or incident response policies are published, suggesting areas for improvement. Overall, the website is professional, trustworthy, and compliant with GDPR requirements, with no signs of malicious activity or content blocking. Strategic enhancements in DNS security and public security policies could further strengthen its posture.

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 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

  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

S-Bahn Berlin GmbH is a large transportation entity focused on urban rail services in Berlin. Its business model revolves around providing reliable public transit, ticketing solutions, and passenger information. The company leverages partnerships with Deutsche Bahn and ticket management services to enhance customer offerings. The website's content and structure indicate a customer-centric approach targeting daily commuters, tourists, and students. Growth indicators include active news updates, event promotions, and digital engagement via social media. The company maintains a strong brand presence and trust signals, supporting its competitive advantage in the regional transit market.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, domain transfer protection, and cookie consent management. The absence of DNSSEC is a minor gap in DNS security. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The login form uses encrypted password fields, and third-party scripts are asynchronously loaded to minimize performance impact. However, the lack of a published security policy or incident response contact reduces transparency. No vulnerability disclosure or security.txt file was found, which could be considered for future improvements. Overall, the site aligns well with standard security best practices for public-facing transit websites.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Implement and publicize a vulnerability disclosure program, including a security.txt file.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by providing data retention policies related to analytics and user data.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system. It integrates Matomo for privacy-focused analytics and Usercentrics for GDPR-compliant consent management. The site uses modern JavaScript and CSS techniques, including lazy loading and responsive design, to optimize performance and user experience. Hosting is managed via RegistryGate GmbH DNS servers, with multiple name servers configured. The site loads asynchronously Adobe DTM scripts for tag management. Performance is moderate, with good mobile optimization and accessibility features. Opportunities exist to improve DNS security and further optimize loading times.
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.
