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

Stone Marine Services is a UK-based marine service and repair specialist established in 2013, providing comprehensive maritime industry solutions including propulsion, propeller repair, stern seal servicing, marine controls, and dynamic positioning. The company targets ferry operators, naval fleets, commercial, military, and luxury vessels worldwide, positioning itself as a dependable and OEM-trained service partner with a global operational footprint. Their business model focuses on operational support, emergency field service, dry dock assistance, and parts supply, supported by strategic partnerships with recognized marine component manufacturers. Technically, the website is built on WordPress with a modern tech stack including Bootstrap, Yoast SEO, WPBakery Page Builder, and Slider Revolution. It integrates Google Analytics, Google Tag Manager, and Google AdSense for analytics and advertising. The site is mobile-optimized with good SEO practices but shows room for improvement in accessibility and performance tuning. Hosting details are not explicit but domain registration and DNS are managed by reputable providers. From a security perspective, the site uses HTTPS with a good SSL configuration and domain transfer protections. However, DNSSEC is not enabled, and several security headers are missing or not explicitly detected. There is no visible privacy policy, terms of service, or incident response information, which are critical for compliance and trust. Cookie consent is implemented, indicating some GDPR awareness. The WHOIS data is consistent and supports the legitimacy of the domain and business. Overall, the website presents a professional and trustworthy front with solid business credibility but requires enhancements in privacy compliance, security policies, and technical security headers to strengthen its security posture and regulatory adherence.

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

6 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 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"

    • 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

  3. 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

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

Stone Marine Services operates in the transportation and energy sectors, focusing on marine vessel maintenance and repair. Their competitive advantage lies in OEM-trained engineers, comprehensive service offerings, and global availability 365 days a year. Revenue streams likely include service contracts, emergency repairs, parts sales, and logistics support. The company targets maritime operators including ferries, naval fleets, commercial, military, and luxury yachts. Partnerships with established marine component manufacturers enhance their service credibility and market reach. The presence of subsidiaries in Namibia and South Africa indicates regional expansion and localized service capabilities. The business model emphasizes operational reliability and minimizing vessel downtime, critical for their target customers. Growth indicators include a well-maintained digital presence, active social media, and strategic partnerships.

Security posture

The current security maturity level is moderate. The website enforces HTTPS and domain transfer protections, which are positive indicators. However, the absence of DNSSEC, lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, and missing privacy and security policies represent compliance and security gaps. No vulnerability disclosure or incident response contacts are provided, limiting transparency and readiness. Cookie consent implementation shows some GDPR compliance effort but is incomplete without a privacy policy. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security culture appears basic and would benefit from formalized policies and technical hardening.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service to meet legal and compliance requirements.
  3. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publicize a security policy and incident response contact information to improve transparency and readiness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  6. Improve accessibility features to enhance usability for all users.
  7. Optimize website performance for faster loading times and better user experience.

Technical notes

Notes

The website is built on a mature WordPress platform using popular plugins and frameworks such as Bootstrap 4, WPBakery Page Builder, and Slider Revolution. It integrates Google Analytics, Tag Manager, and AdSense for analytics and advertising. The site is mobile responsive and SEO optimized with Yoast SEO plugin. Hosting details are not explicit but domain registrar and DNS are managed by reputable providers. Performance is moderate with some room for improvement. Accessibility is basic, indicating potential technical debt in inclusive design. The absence of DNSSEC and some security headers indicates technical risks that could impact business operations if exploited. Overall, the infrastructure is solid but requires modernization in security and accessibility to reduce operational risks.
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.
