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

Rocal Insulating Panels Ltd. is a UK-based manufacturing company with over 30 years of experience specializing in composite doors, uPVC door panels, aluminium windows and doors, and bespoke plastic extrusions. Operating from a large manufacturing facility in North Lincolnshire, they serve a nationwide customer base with a diversified product portfolio and multiple specialist divisions. The website reflects a professional and well-established business with clear branding and trust indicators such as certifications and social media presence. Technically, the website is built on WordPress with modern technologies including jQuery, Bootstrap, and Google Analytics, providing a good user experience and SEO optimization. Security posture is adequate with HTTPS enforced and cookie consent implemented, though there is room for improvement in security headers and incident response transparency. The WHOIS data for the domain 'www.rocal.co.uk' is unavailable and indicates the domain is invalid per Nominet rules, suggesting the main domain might be 'rocal.co.uk' without 'www' or another domain is used. This discrepancy lowers domain registration trustworthiness but does not detract from the professional presentation of the website. Overall, the website is secure, compliant, and credible with minor technical and security enhancements recommended.

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

3 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. 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 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

Rocal holds a strong market position as a medium-sized manufacturer in the UK construction and manufacturing sectors, offering a range of door and extrusion products. Their business model focuses on manufacturing and B2B/B2C sales, supported by a network of partner brands and subsidiaries. The company demonstrates growth and diversification since its founding in 1993, with a clear focus on quality and customer service. Their partnership ecosystem includes related domains such as Endurance Doors and BDC Aluminium, enhancing their market reach. The website content and structure support their business goals effectively, targeting manufacturers, distributors, and end customers seeking high-quality door solutions. The presence of certifications and social media engagement further strengthens their competitive advantage and trustworthiness.

Security posture

The website exhibits a moderate to good security maturity level with HTTPS enabled and a cookie consent mechanism in place, indicating GDPR compliance awareness. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security suggests opportunities for hardening. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of an incident response page or security contact reduces transparency and preparedness perception. There is no evidence of a vulnerability disclosure policy or security.txt file, which could improve security culture and stakeholder trust. Overall, the security posture is solid for a manufacturing business website but could benefit from implementing additional security best practices and incident response readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish an incident response or security contact page to improve transparency and readiness for security incidents.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve security culture.
  4. Verify and correct domain registration details to ensure WHOIS data consistency and improve domain trustworthiness.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities and maintain up-to-date versions.

Technical notes

Notes

The website is built on WordPress CMS using a modern technology stack including jQuery, Bootstrap, Slick Carousel, Google Analytics, and Google Tag Manager. The site uses Typekit fonts and is optimized with Yoast SEO plugin, indicating good SEO practices. Performance is moderate with some reliance on external CDNs for scripts and styles. The site is mobile optimized with responsive design and basic accessibility features. There is some technical debt in the form of missing security headers and minor accessibility improvements.

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.
