The company serves a broad range of industries including automotive, medical, construction, and energy sectors, positioning itself as a trusted manufacturing partner in the UK and Europe. Their website reflects a mature digital presence built on WordPress with modern plugins and themes, offering a professional and user-friendly experience. Security posture is solid with HTTPS and reCAPTCHA integration, though some security headers could be improved. Privacy and cookie policies are present and indicate GDPR 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

6 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

  2. 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

  3. 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';…

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

The company operates primarily in the manufacturing sector, focusing on bespoke plastic injection moulding and tooling services. Their business model is B2B, targeting industries requiring precision plastic components. The company leverages long-term client relationships and certifications such as ISO 9001 and ISO 14001 to maintain competitive advantage. Their service portfolio includes advanced manufacturing techniques like 3D printing and Moldflow analysis, supporting product development and reshoring initiatives. The website's detailed sector pages and testimonials indicate a customer-centric approach and a well-established partnership ecosystem. Growth indicators include a broad service range and emphasis on sustainability. The company maintains a LinkedIn presence, enhancing professional credibility.

Security posture

McLaren Plastics exhibits a good security posture with HTTPS enforced and use of Google reCAPTCHA v3 to protect forms. No exposed sensitive data or vulnerable libraries were detected in the website content. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident and should be implemented to enhance protection against common web attacks. There is no visible incident response or vulnerability disclosure information, which could be improved to demonstrate security maturity. Overall, the site follows basic security best practices but has room for enhancement in header policies and incident transparency.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear incident response and vulnerability disclosure policy or security.txt file to improve transparency and readiness.
  3. Regularly update all WordPress components and plugins to reduce risk of exploitation.
  4. Enhance privacy compliance by explicitly detailing data retention policies and user rights in privacy documentation.
  5. Consider conducting periodic security audits and penetration testing to proactively identify and remediate vulnerabilities.

Notes

The website is built on WordPress CMS using the Elementor page builder and Slider Revolution plugin, indicating a modern and flexible technical infrastructure. It uses Google Fonts and FontAwesome for typography and icons, and integrates Google Analytics and Google Tag Manager for analytics and marketing. The site is mobile-optimized with responsive design and lazy loading for images, contributing to good performance and user experience. Some caching and minification plugins are used, though a minor cache write permission issue was noted. Overall, the technical stack is robust and well-maintained, supporting the business needs effectively.
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.
