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. 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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain dev.honeywell.com points to unregistered service honeywell-dev3-1288403918.us-east-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

  3. 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 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';…

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

Honeywell Technologies operates primarily in the technology and industrial sectors, focusing on automation and autonomy solutions. Its business model is B2B, serving large enterprises and industrial clients with software and hardware solutions for building automation, industrial plants, and process industries. The company maintains a strong brand presence with consistent messaging and a broad partner ecosystem, including investor relations and career portals. The website content and structured data confirm a large enterprise scale with a long history and global reach. Marketing and analytics tools indicate a sophisticated approach to customer insights and engagement. The absence of WHOIS data is consistent with privacy protection practices typical for large corporations. Honeywell's strategic focus on innovation and autonomy positions it well for future growth in industrial technology markets.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent mechanisms actively managing user privacy preferences. The use of reputable third-party scripts such as Adobe DTM, Marketo, and Facebook Pixel is balanced with privacy compliance via OneTrust. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not explicitly found in the provided data and should be verified. Incident response and vulnerability disclosure information are not publicly available, which is a potential area for improvement. Overall, the security posture is strong but could benefit from enhanced transparency and published security policies.

Recommendations

  1. Verify and explicitly implement all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options).
  2. Publish a security.txt file or vulnerability disclosure policy to improve transparency and trust.
  3. Provide clear incident response contact information on the website for security issues.
  4. Continue maintaining and updating cookie consent and privacy compliance mechanisms to align with evolving regulations.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities or privacy risks.

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS, ensuring scalability and content management efficiency. It integrates advanced analytics and marketing tools such as Adobe Analytics, Marketo, and Facebook Pixel, enabling detailed user behavior tracking and marketing automation. Hosting appears to leverage Akamai CDN services, enhancing performance and security. The site is mobile-optimized with responsive design and accessibility features, supporting a broad user base. Performance is fast with modern web technologies and proper SEO meta tags. Technical risks are minimal, but continuous monitoring of third-party scripts and security headers is recommended to maintain a strong security posture.
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.
