Low risk. 1 critical or high finding in SSL/TLS.

Security score

Risk levelLow

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

Mitsubishi Heavy Industries, Ltd. is a large multinational manufacturing and engineering conglomerate headquartered in Japan, with a global presence and diversified business sectors including energy, transportation, aerospace, and defense. The company provides a wide range of industrial products and solutions targeting global industrial customers, investors, and partners. The website reflects a mature digital presence built on Drupal 10, featuring comprehensive navigation, social media integration, and consent management mechanisms. Security posture is strong with HTTPS and consent tools, though explicit security policies and vulnerability disclosure programs are not evident. The absence of WHOIS data is a notable anomaly but does not detract significantly from the overall legitimacy given the professional website and branding. Strategic recommendations include enhancing transparency with published privacy and security policies and adding security headers to improve defense-in-depth.

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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Mitsubishi Heavy Industries operates in essential industrial sectors with a broad product portfolio spanning energy systems, aircraft, space, shipbuilding, transportation, and defense. The business model is based on manufacturing and engineering solutions with a global network supporting regional markets. The company leverages digital tools for marketing and analytics but maintains a conservative approach to privacy disclosures. The presence of ISO45001 certification indicates commitment to occupational health and safety. The website targets multiple stakeholder groups including customers, investors, and job seekers, reflecting a complex ecosystem. Growth and partnership opportunities are implied by the extensive global network and product diversity.

Security posture

The website employs HTTPS with strong SSL configuration and integrates a reputable consent management platform (OneTrust) to comply with cookie regulations. However, the lack of explicit security headers and absence of published security policies or incident response contacts suggest room for improvement in security transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data is a concern for domain registration transparency but may be due to privacy protection or query limitations. Overall, the security posture is good but could be enhanced by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Publish a clear and accessible privacy policy page to improve privacy compliance and user trust.
  2. Add HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Establish and publish a vulnerability disclosure program or security.txt file to facilitate responsible security reporting.
  4. Provide explicit incident response contact information to improve transparency and readiness.
  5. Investigate and clarify domain WHOIS data to enhance domain registration trustworthiness.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, indicating a current and maintainable technology stack. It uses Google Tag Manager for analytics and tracking, and includes slick carousel for UI components. The site is mobile optimized and accessible with good SEO practices including meta tags and Open Graph data. Performance is moderate, likely due to the complexity and size of the site. No major technical debt or outdated libraries were detected in the provided content. Opportunities exist to improve security headers and enhance privacy disclosures to align with best practices.
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.
