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

Kingston Marine Services Ltd is a UK-based specialist company providing diesel and gas engine repairs, maintenance, and spare parts with over 25 years of experience. Established in 1998 by factory-trained Deutz engineers, the company offers a wide range of services including emergency breakdown response, engine overhaul, workshop reconditioning, and specialist machining services. They operate worldwide, serving marine and industrial sectors with a strong emphasis on customer service and health & safety. Technically, the website is built on WordPress with modern plugins such as WPBakery Page Builder and LayerSlider, delivering a professional and mobile-optimized user experience. SEO is supported by Yoast SEO plugin, and the site uses Google Fonts for typography. Performance is moderate with good navigation and content relevance. From a security perspective, the site uses HTTPS but lacks visible security headers and formal privacy or cookie policies, indicating room for improvement in compliance and security posture. The absence of WHOIS data for the domain raises concerns about domain legitimacy, although the website content and business information appear professional and trustworthy. Overall, the website presents a credible business front with strong service offerings but should address privacy compliance and security best practices to enhance trust and reduce risk.

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

10 findings rated critical or high. Fix these first.

  1. DNS health

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

    • High

      Domain Expires Soon

      Domain expires in 19 days

      What to do: Renew domain registration before expiration

  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.

    • 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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

Kingston Marine Services occupies a niche market in marine diesel and industrial gas engine repair and maintenance. Their competitive advantage lies in OEM-standard service at competitive pricing, backed by experienced engineers and global reach. The business model focuses on service delivery, emergency response, and parts support. Revenue streams likely include service contracts, emergency call-outs, parts sales, and engineering consultancy. The target customers are marine operators, offshore oil & gas companies, and industrial clients worldwide. The company demonstrates growth through extensive geographic coverage and a broad service portfolio. The presence of UKAS ISO 9001 certification and positive customer testimonials strengthens their market position. The website does not indicate partnerships or subsidiaries, suggesting an independent operation.

Security posture

The security maturity of the website is moderate. HTTPS is implemented, ensuring encrypted communications. However, the lack of HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No privacy or cookie policies are present, which is a compliance gap under GDPR and related regulations. There is no visible incident response or vulnerability disclosure information, limiting transparency. The absence of WHOIS data for the domain is a red flag for domain legitimacy and trust. Overall, while no critical vulnerabilities are evident, improvements in security headers, privacy compliance, and domain registration transparency are recommended to strengthen the security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to ensure GDPR compliance.
  2. Add and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Publish a security.txt file or vulnerability disclosure policy to improve transparency and incident response readiness.
  4. Verify and update WHOIS domain registration information to ensure legitimacy and trustworthiness.
  5. Conduct regular security audits of WordPress plugins and themes to identify and remediate vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress platform using well-known plugins such as WPBakery Page Builder and LayerSlider, which provide rich content presentation and responsive design. The use of Google Fonts enhances typography. The site is mobile-optimized with good navigation clarity and SEO meta tags implemented via Yoast SEO. Performance is moderate, with no major issues detected in the HTML structure or scripts. However, the absence of security headers and privacy compliance features indicates technical debt in security and regulatory adherence. Hosting provider details are not disclosed, which could be relevant for further infrastructure assessment.
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.
