Risk levelMedium

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

4Plas Ltd is a UK-based supplier specializing in thermoplastic engineering materials, serving the plastics processing industries across the UK and Europe. Their offerings include custom plastic compounds, masterbatches, and distributed engineering materials tailored for injection moulding and extrusion markets. The company positions itself as a technically focused supplier with a broad product range including eco-friendly and recycled materials. The website reflects a professional business presence with clear contact information, product catalogs, and industry certifications. Technically, the website employs a traditional tech stack with jQuery, Modernizr, and Zebra toolkits, alongside FontAwesome for icons. While the site is mobile-optimized and SEO-friendly with proper meta tags, it uses an outdated jQuery version which could pose security risks. The site enforces HTTPS and includes CSRF tokens for form security, but lacks modern security headers and explicit incident response or security policy disclosures. From a security perspective, the site demonstrates good baseline practices such as HTTPS and secure forms but could improve by updating libraries, adding security headers, and publishing incident response information. The absence of WHOIS data limits transparency about domain registration, though the website content and contact details support legitimacy. Privacy and cookie policies are present with consent mechanisms, indicating GDPR awareness. Overall, 4Plas.com is a credible and professional website for a niche manufacturing supplier with moderate technical maturity and a solid security baseline. Enhancements in security headers, library updates, and transparency around domain registration would strengthen 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

4 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. 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

4Plas operates in the manufacturing sector, focusing on supplying engineering plastics and compounds to UK and European plastics processors. Their business model centers on product distribution and custom compounding services, targeting industrial clients requiring technical materials for injection moulding and extrusion. The company leverages industry certifications and a technical product range to differentiate itself. The website supports lead generation through account creation, contact forms, and newsletter signups. Partnerships with recognized bodies like the British Plastics Federation and UL Certification enhance credibility. The company appears to be small-sized with a focused market niche and no publicly listed parent or subsidiaries. The digital presence is professional but could benefit from modernization and enhanced transparency.

Security posture

The website enforces HTTPS and includes CSRF tokens, indicating attention to basic web security. However, the use of an outdated jQuery version introduces potential vulnerabilities. The absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No explicit security or incident response policies are published, and no security.txt or vulnerability disclosure mechanisms are found. Privacy and cookie policies are comprehensive and GDPR compliant, reflecting good data protection awareness. Overall, the security posture is moderate but could be significantly improved by updating libraries, adding security headers, and publishing incident response information.

Recommendations

  1. Update jQuery and other JavaScript libraries to the latest secure versions to mitigate known vulnerabilities.
  2. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and security posture.

Technical notes

Notes

The website uses a traditional front-end stack with jQuery 1.7.1, Modernizr, and Zebra toolkits, supported by FontAwesome icons. It is mobile-optimized with responsive CSS and includes SEO-friendly meta tags. Performance is moderate, with no explicit hosting provider identified. The site lacks a modern CMS or framework indication, suggesting a custom or legacy build. The use of older JavaScript libraries introduces technical debt and security risks. The site includes multiple interactive forms with client-side validation and CSRF protection. Integration with AddThis provides social sharing and tracking capabilities. Overall, the technical infrastructure is functional but would benefit from modernization and security hardening.
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.
