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

Hallesche Verkehrs-AG (HAVAG) is a regional public transportation company serving the Halle (Saale) and Merseburg areas in Germany. It operates under the Mitteldeutscher Verkehrsverbund and is part of the larger SWH group. The website provides comprehensive information about public transport services, ticketing options, customer service, and multimodal transport offers. It targets local residents and commuters seeking reliable public transit information and services. The company maintains a medium-sized regional presence with a clear business model focused on public transportation and customer support. Technically, the website employs a modern technology stack including jQuery, Leaflet for mapping, FontAwesome icons, and Matomo for analytics, complemented by Usercentrics for consent management. The site is hosted by Vautron Rechenzentrum AG and shows good mobile optimization and SEO practices. The infrastructure is stable with HTTPS enforced, though some security headers are not explicitly confirmed. Privacy compliance is well addressed with visible cookie consent and a detailed privacy policy. From a security perspective, the site demonstrates good practices such as HTTPS usage and consent management but lacks explicit incident response contacts and vulnerability disclosure mechanisms. DNSSEC is not enabled, which is a recommended improvement. No critical vulnerabilities or suspicious content were detected. Overall, the site is trustworthy, professional, and compliant with GDPR requirements. The overall risk is low, with recommendations focusing on enhancing DNS security, publishing security.txt, and adding explicit security headers to strengthen the security posture further. The website is suitable for its audience and business purpose, with a strong alignment between domain registration data and business claims.

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

HAVAG holds a solid regional market position as a public transport operator in Halle (Saale) and Merseburg, integrated within the Mitteldeutscher Verkehrsverbund. Its competitive advantage lies in its affiliation with the SWH group, providing synergies with sister companies in energy, water, and IT sectors. Revenue streams primarily come from ticket sales, subscriptions, and public transport services. The target customers are local commuters, students, and residents relying on public transit. Growth indicators include digital services like online subscriptions and mobile apps. The partnership ecosystem is robust, linking multiple related companies under the SWH umbrella, enhancing service integration and operational efficiency. Strategic observations suggest a focus on multimodal transport and customer-centric digital services to maintain and grow market share.

Security posture

The website exhibits a mature security posture with mandatory HTTPS and consent management for privacy compliance. Security headers are partially confirmed but could be improved by explicitly implementing CSP, X-Frame-Options, and other headers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public incident response contact and vulnerability disclosure policy indicates room for improvement in security transparency and readiness. DNSSEC is not enabled, which is a recommended enhancement to protect DNS integrity. Overall, the site is secure for its business context but should adopt additional best practices to strengthen defenses and compliance further.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Implement and explicitly configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Add a dedicated incident response contact email (e.g., security@ or abuse@) on the website for transparency and quick reporting.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities and ensure compliance.

Technical notes

Notes

The website uses a combination of jQuery, Leaflet for interactive maps, FontAwesome for icons, and Matomo for analytics, indicating a moderately modern and functional tech stack. Usercentrics is used for GDPR-compliant consent management. The site is hosted by Vautron Rechenzentrum AG, a reputable hosting provider. Performance is moderate with good mobile optimization and basic accessibility features. The CMS is not explicitly identified, suggesting a custom or proprietary solution. SEO is well addressed with proper meta tags and structured navigation. Technical risks include lack of DNSSEC and incomplete security header implementation, which could be addressed to reduce attack surface and improve resilience.
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.
