Mitsubishi Electric Corporation operates a comprehensive global website showcasing its position as a leading manufacturer of electrical and electronic products across multiple sectors including energy, transportation, and industrial automation. The website targets a global industrial and commercial audience with a broad portfolio of products and services. Technically, the site is built on Adobe Experience Manager, employs modern JavaScript libraries such as jQuery, and integrates advanced consent management and analytics tools, reflecting a mature digital infrastructure. Security posture is strong with HTTPS enforcement, security headers, and cookie consent mechanisms, though explicit security policies and incident response contacts are not publicly detailed.

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

4 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 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. 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
    • 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

Mitsubishi Electric is positioned as a global leader in manufacturing electrical and electronic products with a diversified portfolio spanning air conditioning, automotive equipment, factory automation, semiconductors, and space systems. The business model focuses on manufacturing and global distribution, targeting industrial and commercial sectors worldwide. The website links to numerous regional domains, indicating a strong international footprint. The company maintains a professional online presence with comprehensive privacy and cookie policies, reflecting compliance with global data protection standards. The lack of visible direct contact details suggests a preference for controlled communication channels via contact forms. No affiliate or partner domains were explicitly identified beyond regional Mitsubishi Electric sites.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, presence of key security headers, and integration of a consent management platform for GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response information, or vulnerability disclosure program limits transparency. The WHOIS data unavailability is a concern but may be due to privacy protection or registry policies rather than malicious intent. Overall, the site aligns with good security practices expected of a large multinational corporation but could improve transparency on security governance and incident handling.

Recommendations

  1. Publish a dedicated security policy page detailing security governance and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear contact information for the Data Protection Officer or security incident response team.
  4. Enhance WHOIS transparency if possible to improve domain registration trustworthiness.
  5. Continue maintaining and updating privacy and cookie consent mechanisms to align with evolving regulations.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS, and uses modern JavaScript libraries including jQuery 3.7.1. It integrates Google Tag Manager and Adobe Helix RUM for analytics and performance monitoring, alongside OneTrust for consent management. Hosting appears to leverage Akamai CDN services, enhancing global performance and security. The site is mobile optimized with good accessibility and SEO practices. Performance is moderate, likely due to rich content and global reach. No deprecated or vulnerable libraries were detected. Opportunities exist to improve technical transparency around security policies and incident response mechanisms.
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.
