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

CSX Corporation operates as a major North American transportation company specializing in rail freight, intermodal, and rail-to-truck transload services. The company serves a broad customer base including industrial clients, investors, suppliers, and community stakeholders. Their market position is that of a large enterprise with extensive infrastructure across the eastern, midwestern, and southern United States as well as parts of Canada. The website reflects a mature business model focused on logistics and freight transportation with strong investor relations and community engagement components. Technically, the website is built on the Mura CMS platform with modern JavaScript libraries such as jQuery and Dojo, and integrates Google Tag Manager for analytics. The site demonstrates good mobile optimization, accessibility features, and SEO practices. Performance is moderate with room for improvement in loading speed and security header implementation. From a security perspective, the site enforces HTTPS and includes a cookie consent mechanism aligned with privacy regulations. A responsible disclosure policy is published, though no dedicated security contact emails were found. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of WHOIS registration details reduces transparency and slightly impacts trustworthiness. Overall, CSX.com presents a professional, secure, and compliant digital presence consistent with a large transportation enterprise. The main risks relate to WHOIS data unavailability and minor security header enhancements. Strategic recommendations include improving security header coverage, publishing a security.txt file, and enhancing incident response contact visibility.

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. 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';…

  3. 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

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

CSX holds a strong market position as a leading freight transportation provider in North America, leveraging rail and intermodal logistics to serve diverse industries. Their business model focuses on efficient supply chain solutions, real estate services, and customer-centric operations. The company targets industrial shippers, investors, suppliers, and community partners. Growth indicators include active investor communications, sustainability initiatives, and community investment programs. The partnership ecosystem includes ShipCSX and investor portals, enhancing service delivery and transparency. The website content and structure reflect a mature, enterprise-grade operation with consistent branding and trust signals such as awards and corporate social responsibility reports.

Security posture

The security posture of CSX.com is solid with HTTPS enforced and privacy compliance mechanisms in place. The presence of a responsible disclosure policy indicates awareness of vulnerability management. No critical security headers were detected in the HTML content, suggesting an opportunity for improvement in defense-in-depth. No exposed credentials or sensitive data were found. The site uses modern libraries without known vulnerabilities. Incident response contact channels could be more explicit with dedicated security emails. Overall, the site demonstrates a good security maturity level appropriate for a large enterprise but could benefit from enhanced header policies and formalized security.txt adoption.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a security.txt file at the root domain to standardize vulnerability disclosure and improve communication with security researchers.
  3. Enhance incident response readiness by providing dedicated security contact emails (e.g., security@csx.com) on the responsible disclosure page.
  4. Regularly audit third-party scripts and tracking pixels to ensure compliance with privacy policies and minimize data leakage risks.
  5. Improve website performance by optimizing assets and leveraging caching to enhance user experience and reduce load times.

The website is powered by Mura CMS version 10.0.698, utilizing jQuery 2.1.4 and Dojo Toolkit for UI components and ArcGIS integration. Google Tag Manager is used for analytics and marketing tracking. The site includes accessibility features and responsive design elements, supporting a good mobile experience. Performance is moderate, with potential improvements in asset optimization.

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.
