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

Dunraven Windows is a well-established, second-generation family-run business specializing in the manufacturing and installation of bespoke double glazing products including windows, doors, conservatories, and replacement roofs. Operating primarily in Wales and South West England, the company leverages over 40 years of experience and in-house manufacturing capabilities to deliver high-quality home improvement solutions. Their market position is strengthened by certifications such as ISO9001, FENSA approval, PAS24, and Secured by Design standards, alongside positive customer reviews and a decade-long product guarantee. Technically, the website is built on WordPress with modern tracking and analytics tools including Google Tag Manager, Microsoft Clarity, and PixelYourSite. The site demonstrates good mobile optimization, accessibility, and SEO practices, though there is room for improvement in security headers and explicit security policy disclosures. Hosting appears stable with IONOS SE as registrar and Suntrade Group as nameservers. From a security perspective, the site uses HTTPS with a clientTransferProhibited domain status, indicating domain transfer protection. Cookie consent mechanisms and privacy policies are in place, supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a published security policy or incident response page and missing security headers like Content-Security-Policy suggest areas for enhancement. Overall, Dunraven Windows presents a trustworthy and professional online presence with strong business credibility and compliance posture. Strategic recommendations include enhancing security headers, publishing a security policy, and considering a vulnerability disclosure mechanism to further strengthen trust and security maturity.

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

Dunraven Windows holds a strong regional market position in the home improvement sector, focusing on double glazing and bespoke manufacturing. Their competitive advantage lies in in-house production, extensive product range, and long-standing customer trust evidenced by certifications and reviews. The business model combines manufacturing with direct installation services, targeting homeowners seeking quality and bespoke solutions. Revenue streams likely include product sales, installation services, and finance options. The company maintains a diverse and growing workforce and engages in digital marketing and analytics to optimize customer acquisition and service delivery. Partnerships with finance providers and presence on review platforms enhance their ecosystem and customer confidence.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and domain transfer protection enabled. Cookie consent and privacy policies align with GDPR requirements. However, the lack of explicit security headers such as Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy indicates partial implementation of best practices. No incident response or security policy pages were found, which limits transparency and preparedness communication. No vulnerabilities or exposed sensitive data were detected in the content. The use of third-party analytics and advertising scripts is managed with consent, reducing privacy risks. Overall, the security posture is good but could be improved by adopting additional headers and publishing formal security documentation.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy headers to enhance browser security.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Consider creating and hosting a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize tracking risks.
  5. Enhance user trust by clearly communicating data retention policies and security measures in privacy documentation.

Technical notes

Notes

The website is built on WordPress CMS, utilizing jQuery and modern analytics tools such as Google Tag Manager and Microsoft Clarity. The site is hosted with a registrar IONOS SE and uses Suntrade Group nameservers. Performance is moderate with good mobile responsiveness and accessibility features. SEO is well implemented with proper meta tags, Open Graph, and JSON-LD structured data. The site uses lazy loading for images and asynchronous script loading to optimize load times. Technical debt appears low, but security header implementation is incomplete. The infrastructure supports a professional and scalable online presence with opportunities for further modernization in security and performance optimization.
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.
