Medium risk. 2 critical or high findings in Security headers and GDPR outside view.

Security score

74/100

Risk levelMedium

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

Siem Shipping UK Limited operates as a specialised shipping and logistics company, providing a diversified fleet and services including car carriers, offshore support vessels, ship management, leasing solutions, and global logistics. The company positions itself as a trusted partner connecting industries and communities with a customer-centric approach. The website reflects a medium-sized enterprise with professional branding and consistent messaging aligned with its parent company, Siem Industries Inc. Technically, the website is built on WordPress using modern themes and optimization plugins, ensuring good performance and mobile responsiveness. Security posture is solid with HTTPS and no visible vulnerabilities, though it lacks some advanced security headers and explicit privacy and cookie policies. The absence of WHOIS data for the domain introduces some uncertainty about domain registration legitimacy, but the website content and structure support a credible business presence. Overall, the site is well-designed and functional but would benefit from enhanced privacy compliance and security transparency.

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

2 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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Siem Shipping UK Limited serves the transportation and energy sectors with a comprehensive fleet and diversified service offerings. Its business model includes direct shipping services, offshore vessel operations, ship management, and leasing solutions, targeting industrial clients and offshore oil-service sectors. The company leverages its parent group, Siem Industries Inc., for market positioning and operational scale. The website indicates active content updates and a focus on sustainability and innovation, suggesting growth orientation. The partnership with bisongrid.dev for technical support is evident. The absence of explicit phone contact may indicate a preference for digital communication channels. The company maintains a professional online presence but should improve transparency around privacy and security policies to strengthen trust.

Security posture

The website employs HTTPS with a valid SSL configuration, ensuring encrypted communications. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No exposed sensitive data or vulnerable libraries were detected. The site does not provide a security policy or incident response contact, which are important for compliance and trust. Privacy compliance is minimal, with no visible privacy or cookie policies, potentially exposing the company to regulatory risks under GDPR. The use of Google Analytics and Tag Manager indicates moderate user tracking, but without clear privacy disclosures. Overall, the security posture is adequate but could be significantly improved with better policy transparency and technical controls.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a security policy page and incident response contact information to enhance transparency and readiness.
  4. Conduct a WHOIS domain registration review to ensure domain legitimacy and update registration details if necessary.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on WordPress with the Breakdance theme and uses WP Rocket for performance optimization, including lazy loading of scripts and images. It integrates Google Fonts and Google Tag Manager for styling and analytics. The site demonstrates good SEO practices with meta tags, Open Graph, and JSON-LD structured data for organization and articles. Performance is optimized with minified CSS and JS and DNS prefetching. Mobile optimization is good, with responsive design and viewport settings. Accessibility is basic but could be improved. No major technical debt or outdated libraries were detected. Hosting provider details are not explicit. Overall, the technical infrastructure supports a professional and performant web presence.
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.
