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

Siemens is a globally recognized technology leader specializing in industry, infrastructure, and mobility solutions driven by digital transformation. The website reflects a mature enterprise with a strong market position and a comprehensive portfolio of services including industry automation, infrastructure solutions, and mobility technologies. The digital presence is modern, leveraging advanced web technologies such as Vue.js, Apollo GraphQL, and integrated analytics platforms like Matomo and Adobe Analytics. Privacy and cookie policies are well established with active consent management, indicating compliance with GDPR and related regulations. Security posture is solid with HTTPS enforcement and consent-based tracking, though additional security headers and explicit security policies could enhance protection. The absence of WHOIS data is noted but likely due to registry privacy or query limitations rather than suspicious activity. Overall, the site demonstrates high professionalism, trustworthiness, and technical sophistication suitable for an enterprise of Siemens' stature.

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

1 finding rated critical or high. Fix these first.

  1. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Siemens operates as an essential entity in the technology and industrial sectors, targeting industry professionals, investors, and global customers. Its business model focuses on delivering integrated technology solutions and digital transformation services across energy, transportation, and infrastructure sectors. The company maintains a strong partnership ecosystem, including the Siemens Xcelerator Marketplace and official press channels. The website's content and structure support a high level of user engagement and trust, with clear navigation and comprehensive corporate information. Siemens' global reach and enterprise scale are evident, though specific founding year and subsidiary details are not disclosed on the site.

Security posture

The website exhibits a mature security posture with HTTPS enforced and use of consent management tools to regulate analytics and marketing tracking. Security best practices include no visible exposure of sensitive data and secure form implementations. However, the site lacks some advanced security headers such as Content-Security-Policy and Strict-Transport-Security, and does not publish a dedicated security policy or vulnerability disclosure program. Incident response contact information is not publicly available. The extensive use of third-party scripts necessitates ongoing security audits to mitigate potential risks. Overall, the security posture is strong but could benefit from enhanced transparency and additional technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen defense against common web attacks.
  2. Publish a dedicated security policy and incident response information to improve transparency and user trust.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance data retention transparency by detailing policies related to analytics and user data storage.
  5. Regularly review and audit third-party scripts and integrations to minimize security risks and ensure compliance.

Technical notes

Notes

The Siemens website is built on a modern technology stack featuring Vue.js for frontend rendering and Apollo GraphQL for data management. It integrates multiple analytics and marketing tools including Matomo, Adobe Analytics, Eloqua, and Usercentrics for consent management. The site demonstrates fast performance, excellent mobile optimization, and good accessibility features. The content management system appears proprietary, tailored to Siemens' needs. The site uses advanced image loading techniques and preloading for performance optimization. However, hosting provider details are not explicitly identified. The technical infrastructure supports a robust and scalable digital presence suitable for a global enterprise.
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.
