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

Verkehrsverbund Bremen/Niedersachsen GmbH (VBN) operates as a regional public transportation authority providing integrated ticketing, timetable information, and mobility services across Bremen and Lower Saxony. The website serves a broad audience including commuters, families, students, and groups, offering comprehensive transport options and customer support. The business model focuses on facilitating seamless public transport usage through digital platforms and partnerships with transport operators. Technically, the website is built on TYPO3 CMS with modern JavaScript libraries such as jQuery, Bootstrap, and Leaflet for interactive maps and widgets. The integration of HAFAS public transport widgets enhances user experience for timetable and ticketing queries. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS, uses cookie consent mechanisms, and follows good security practices, though explicit security headers like Content-Security-Policy could be improved. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong with clear GDPR-aligned policies and cookie management. Overall, the website presents a trustworthy, professional, and user-friendly platform supporting VBN's mission. Strategic improvements in security policy transparency and header implementation would further enhance 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

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. 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

VBN holds a strong regional market position as a transportation integrator in Germany, focusing on public transit coordination and ticketing. Its competitive advantage lies in comprehensive service coverage, digital integration with partner platforms, and customer-centric offerings such as mobility training and accessibility information. Revenue streams likely include ticket sales and public funding. The partnership ecosystem includes fahrplaner.de and related ticketing services. Growth indicators include active promotions and digital service expansions. The company operates in a regulated sector with a focus on public service and sustainability.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent, and no visible security flaws. However, the absence of a published security policy or incident response contacts limits transparency. Compliance with GDPR is evident, but further enhancements like security.txt publication and additional HTTP security headers would strengthen defenses. The site shows readiness for incident response but lacks explicit communication channels for security issues. Overall, the security culture appears adequate but could benefit from formalization.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add and enforce HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy.
  3. Publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance user trust by providing more visible trust signals such as certifications or compliance badges.

Technical notes

Notes

The website uses a robust TYPO3 CMS platform combined with modern JavaScript libraries for UI and interactive features. Integration with external transport data services (HAFAS) is well implemented. Performance is moderate with room for optimization, especially in asset loading and caching. Mobile responsiveness and accessibility are well addressed. Technical debt appears low, but security header implementation and hosting provider transparency could be improved. Overall, the technical infrastructure supports the business needs 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.
