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

7 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

  • Email security: did not complete in this scan.
  • 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

SEACOR Holdings maintains a diversified portfolio of subsidiaries in the transportation and energy logistics sectors, including companies like Fairwater, US Ocean, and Trailer Bridge. The company leverages its legacy businesses and strategic investments to maintain a competitive edge in maritime transportation and logistics. Their business model focuses on asset quality, technology adoption, and a disciplined investment approach to drive value creation. The presence of multiple recent news releases indicates active management and strategic divestitures or acquisitions, signaling dynamic market engagement. The company targets commercial clients requiring specialized transportation and logistics services, particularly in the U.S. market. Partnerships and joint ventures, such as with Crowley and Kotug, enhance their operational footprint and market reach. The website content and structure support a professional image aimed at stakeholders, investors, and business partners.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms from automated abuse. CSRF tokens are implemented for form submissions, indicating attention to common web security threats. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. No published security policy or incident response contact information is available, which could hinder timely reporting and handling of security incidents. There is no vulnerability disclosure or security.txt file found, limiting transparency for security researchers. No vulnerable libraries or exposed sensitive data were detected. Overall, the security posture is good but could be improved by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Add an explicit cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Establish and publish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using Craft CMS, leveraging modern front-end technologies such as Bootstrap for responsive design and jQuery for DOM manipulation. It integrates FontAwesome for icons and Slick Carousel for interactive sliders. Analytics and user behavior tracking are implemented via Google Analytics, Google Tag Manager, and Hotjar, indicating a focus on data-driven insights. The site loads scripts asynchronously to optimize performance, though overall loading speed is moderate. Accessibility features are basic but present, with some ARIA attributes and semantic HTML elements. SEO is supported by proper meta tags and structured navigation. The technical infrastructure is solid but could benefit from enhanced security headers and performance optimizations to reduce technical debt and improve resilience.
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.
