Risk levelMedium

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

Rheinmetall AG is a leading integrated international technology group headquartered in Düsseldorf, Germany, specializing in defense systems and innovative industrial technologies for civilian markets. The company positions itself as a key player in the defense industry while driving sustainable innovation across multiple sectors. The website reflects a professional corporate presence with comprehensive information about its business sectors, sustainability goals, and corporate responsibility. Technically, the site is built on modern frameworks such as Nuxt.js and Vue.js, with good mobile optimization and accessibility features. Security posture is strong with HTTPS enforcement and security headers, though explicit security policies and incident response details are not publicly available. Privacy compliance is well addressed with GDPR-aligned privacy and cookie policies and a consent management platform. The absence of WHOIS registration data is a transparency concern but does not detract significantly from the overall legitimacy given the professional presentation and trust signals. Strategic recommendations include publishing detailed security policies, improving transparency on domain registration, and enhancing incident response contact information.

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

3 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.

    • 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.

    • 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

Rheinmetall operates as an essential entity in the technology sector, focusing on defense, industrial technology, and mobility solutions. Its market position as a leading international system house in defense is supported by a broad portfolio of products and services, including digitalization and training. The company targets government agencies, industry partners, and investors, leveraging certifications such as ISO 9001 and ISO 14001 to reinforce quality and environmental standards. The business model integrates defense and civilian markets, emphasizing sustainability with a goal of CO2 neutrality by 2035. The website content and structure indicate a mature digital presence with clear branding and consistent messaging. The company’s ecosystem includes multiple subsidiaries and partnerships, though specific related domains were not identified in the provided data.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, comprehensive security headers, and a cookie consent mechanism aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly available security policy or incident response plan limits transparency and preparedness perception. No vulnerability disclosure program or security.txt file was found, which could be improved to foster responsible vulnerability reporting. The use of third-party scripts like Google Tag Manager and Usercentrics CMP is managed with consent but requires ongoing monitoring for security risks. Overall, the security posture is solid but could benefit from enhanced communication and formalized security governance disclosures.

Recommendations

  1. Publish a detailed security policy and incident response plan on the website to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance contact information specifically for security incidents, including dedicated email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Verify and update WHOIS registration data to improve domain transparency and legitimacy.

Technical notes

Notes

The website is built using modern JavaScript frameworks Nuxt.js and Vue.js, providing a responsive and accessible user experience. It employs Usercentrics for GDPR-compliant consent management and Google Tag Manager for analytics. The site uses optimized images with multiple formats (AVIF, WebP, JPEG) for performance. Security headers and HTTPS are properly configured, contributing to a secure browsing environment. The site’s performance is moderate, with good mobile optimization and SEO practices. No CMS was explicitly detected, suggesting a custom or headless CMS approach. Hosting provider details were not identified. Opportunities exist to enhance technical documentation and security disclosures to reduce technical debt and improve operational transparency.
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.
