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

Holyhead Marine Services Ltd. is a UK-based company specializing in the construction, refit, and repair of aluminum, steel, and GRP boats up to 24 meters or 100 tons displacement. Their market position is that of a regional specialist serving commercial, military, and harbor authority clients with bespoke marine vessel solutions. The company offers key services including new builds of pilot, patrol, military, commercial, and rescue boats, as well as fleet support and repair services. The website reflects a professional and consistent brand image with clear navigation and detailed service descriptions. Technically, the website is built on WordPress using a modern stack of plugins and libraries such as LayerSlider, Revolution Slider, Contact Form 7, and Google Site Kit for analytics and marketing. The site is mobile-optimized with good SEO practices and moderate performance. However, there is room for improvement in accessibility and security headers implementation. From a security perspective, the site enforces HTTPS and uses CAPTCHA on forms, but lacks important security headers and a cookie consent mechanism, which are critical for GDPR compliance. No explicit security or incident response policies are published. The WHOIS data for the 'www' subdomain is invalid due to domain naming rules, but the main domain is active and consistent with the business, slightly reducing trust but not significantly. Overall, the website is credible and professional with a solid business presence but would benefit from enhanced security practices and privacy compliance measures to improve trust 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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Holyhead Marine operates in the transportation and manufacturing sectors, focusing on marine vessel construction and maintenance. Their business model is B2B, targeting commercial and military maritime clients. The company leverages ISO certifications as a competitive advantage and maintains an active social media presence to engage with stakeholders. Revenue streams likely include new builds, refit and repair contracts, and fleet support services. The website content and structure indicate a medium-sized enterprise with a stable market position in the UK. There is no indication of parent or subsidiary companies. The company demonstrates a commitment to quality and safety through certifications and detailed service offerings.

Security posture

The security maturity level is moderate. HTTPS is properly implemented, and forms use CAPTCHA to prevent automated abuse. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. There is no visible vulnerability disclosure or incident response information, which could hinder timely handling of security incidents. GDPR compliance is partially addressed with a privacy policy but lacks cookie consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The security culture appears basic but could be improved with formal policies and transparency.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish a security policy and incident response contact information to build trust and readiness for security events.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  5. Enhance accessibility features to improve usability for all users and meet compliance standards.

Technical notes

Notes

The website uses a well-established CMS (WordPress) with a variety of plugins for sliders, forms, and analytics. The tech stack includes jQuery, Google Fonts, and several slider plugins, indicating a reliance on third-party components that require regular maintenance. Performance is moderate with some heavy slider assets. The site is mobile responsive and SEO optimized with proper meta tags and structured data (JSON-LD). There is no evidence of advanced frameworks or custom backend technologies. Hosting provider details are not disclosed. Technical risks include potential plugin vulnerabilities and missing security headers. Opportunities exist to modernize the stack and improve performance and security configurations.
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.
