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

North Star is a UK-based marine infrastructure support company specializing in offshore energy sectors including renewables and conventional energy. The company offers a range of services such as offshore wind support vessels, emergency response, platform supply, patrol and research, and rescue and maintenance. Their market position is that of an established medium-sized player with decades of marine experience and a modern fleet. The website is professionally designed, mobile-optimized, and provides comprehensive compliance and contact information, indicating a mature digital presence. Technically, the website is built on Webflow CMS, leveraging modern web fonts, analytics, and consent management tools. Performance and accessibility are rated highly, with fast loading times and good SEO practices. Security posture is strong with HTTPS enforced and cookie consent implemented, though some security headers could be improved. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data reveals a domain registration anomaly: the domain www.northstarshipping.co.uk is reported as unregistered due to naming rules violation by Nominet UK. Despite this, the website content is accessible and professional, suggesting the domain may be a subdomain or alias. This discrepancy lowers the domain legitimacy score and warrants caution. Overall, North Star's website demonstrates a solid business and technical foundation with good security and privacy compliance. Strategic recommendations include enhancing security headers, clarifying domain registration status, and adding incident response information to further strengthen trust and compliance.

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. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 13 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

North Star operates in the energy and transportation sectors, focusing on offshore marine infrastructure support. Their business model centers on providing specialized vessel services and emergency response capabilities to offshore wind farms and conventional energy installations. The company targets energy operators, government agencies, and scientific organizations. The presence of a dedicated careers subdomain indicates ongoing growth and talent acquisition efforts. The website's news section and compliance pages reflect transparency and active engagement with regulatory requirements. Partnerships with shipbuilders like VARD are highlighted, reinforcing industry collaboration. The company appears well-positioned in a niche market with a focus on sustainability and safety.

Security posture

The website employs HTTPS with a strong SSL configuration, ensuring encrypted communications. Cookie consent is implemented with an opt-in mechanism, supporting privacy compliance. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy are not evident and should be added to mitigate common web attacks. No incident response or security contact information is provided, which is a gap in security transparency. The use of third-party scripts like Google Analytics and Jetboost is standard but requires ongoing monitoring for vulnerabilities. No exposed credentials or sensitive data were found in the HTML content. Overall, the security posture is good but can be improved with enhanced headers and incident response details.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  2. Clarify domain registration status and ensure domain WHOIS data aligns with website ownership to improve trust.
  3. Add an incident response page or security contact email to enhance transparency and readiness.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update as needed.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

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.
