Knorr-Bremse AG · Transportation · Germany

Medium risk. 6 critical or high findings in GDPR outside view and SSL/TLS.

Security score

52/100

Risk levelMedium

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

Knorr-Bremse AG is a global leader in manufacturing braking systems and safety-critical sub-systems for rail and commercial vehicles. With a history spanning over 28 years, the company holds a strong market position as an innovator in mobility and transport technologies. Their business model focuses on delivering advanced braking and safety solutions, complemented by comprehensive investor relations and career development programs. Technically, the website is built on a modern Angular framework, hosted on Nginx and Amazon CloudFront, with good SEO and accessibility features. However, a critical security gap exists due to the absence of a valid SSL/TLS certificate, resulting in no HTTPS support, which significantly impacts the security posture. The site implements strong security headers and content policies but lacks advanced SSL configurations and session management. Privacy compliance is well addressed with comprehensive policies and consent mechanisms. Overall, the website is professional and trustworthy but requires urgent SSL deployment to enhance security and user trust.

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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • 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

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Knorr-Bremse AG operates in the transportation sector, specializing in braking systems for rail and commercial vehicles. The company maintains a mature domain and consistent registrant information, reflecting a stable and legitimate business presence. Their extensive subsidiary network and global reach indicate a large enterprise scale. The business model leverages innovation and safety-critical technology to maintain market leadership. Investor relations and compliance transparency further strengthen their credibility. The target audience includes industry professionals, investors, and potential employees. The company’s strategic focus on sustainability and cultural change highlights forward-looking growth initiatives.

Security posture

The website demonstrates moderate security maturity with implementation of key HTTP security headers such as CSP, X-Frame-Options, and X-XSS-Protection. However, the lack of a valid SSL certificate and absence of HTTPS severely undermine the security posture, exposing users to risks such as data interception and man-in-the-middle attacks. No advanced SSL features like OCSP stapling or session resumption are enabled. There is no public incident response or vulnerability disclosure policy found. Privacy policies are comprehensive and GDPR compliant, indicating good data protection practices. Immediate remediation of SSL/TLS issues is critical to elevate security maturity.

Recommendations

  1. Deploy a valid SSL/TLS certificate and enable HTTPS across the entire domain.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and strong cipher suites.
  3. Implement HSTS with includeSubDomains and preload flags for enhanced security.
  4. Enable OCSP stapling to improve certificate revocation checks.
  5. Publish a vulnerability disclosure policy and incident response contact information to improve transparency and security culture.

Technical notes

Notes

The website uses Angular 18 framework with a modular JavaScript architecture and SVG iconography, hosted on Nginx behind Amazon CloudFront CDN. The site is mobile optimized with responsive design and good accessibility features. SEO is supported by comprehensive meta tags, Open Graph data, and JSON-LD structured data. Performance metrics are not available, but the use of CDN and modern frameworks suggests moderate to good performance. The absence of HTTPS is a major technical risk. No common CMS is detected, indicating a custom or proprietary content management solution.
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.
