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

Miers Construction Products Limited is a UK-based supplier specializing in high-quality construction materials and building accessories. Established in 2011, the company operates multiple depots across the UK, serving contractors, builders, and civil engineering projects nationwide. Their business model focuses on providing a wide range of products with expert support and efficient delivery, positioning them as a leading supplier in the construction sector. The website reflects a professional and consistent brand image, supported by partnerships with well-known construction brands and certifications such as BBA approval. Technically, the website is built on modern frameworks including Nuxt.js and Tailwind CSS, ensuring good mobile responsiveness and SEO optimization. The presence of Google Tag Manager indicates active analytics and marketing efforts. Security posture is solid with HTTPS enforced and secure form handling, though some security headers could be improved. Privacy compliance is strong, with a comprehensive GDPR-compliant privacy policy and clear contact information. Overall, the security posture is good with no critical vulnerabilities detected. The absence of WHOIS data due to domain naming rules violation is a limitation in verifying domain legitimacy, but the website content and business information appear trustworthy and professional. Strategic recommendations include enhancing security headers, implementing explicit cookie consent, and publishing incident response policies to further strengthen trust and compliance. This assessment concludes that Miers Construction Products maintains a robust online presence aligned with its business goals, with moderate technical maturity and a positive security and privacy stance, suitable for its industry and customer base.

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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  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 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

Miers Construction Products holds a strong market position as a medium-sized UK supplier of construction materials, leveraging partnerships with top brands and a network of depots for nationwide coverage. Their competitive advantages include expert product knowledge, a broad product range, and efficient delivery services. The business model is B2B focused, targeting contractors and builders, with revenue streams likely from product sales and distribution partnerships. Growth indicators include recent depot expansions and new product brochures. The company ecosystem includes partnerships with SIG plc and other construction product suppliers, enhancing their market reach and product offerings. Operationally, the company emphasizes customer service and compliance, supported by detailed privacy and contact information on their website.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure form submissions. However, some standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly detected, representing an area for improvement. No exposed sensitive data or vulnerable libraries were found in the analysis. Privacy policies are comprehensive and GDPR compliant, indicating good data protection practices. Incident response and vulnerability disclosure policies are absent, which could be addressed to improve readiness and transparency. Overall, the security culture appears positive but could benefit from formalized policies and enhanced header configurations.

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. Introduce an explicit cookie consent mechanism to comply fully with privacy regulations and enhance user trust.
  3. Publish incident response and vulnerability disclosure policies to demonstrate security maturity and provide clear channels for reporting issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced through dependencies.
  5. Enhance accessibility features and conduct periodic security training for staff to foster a strong security culture.

Technical notes

Notes

The website is built using modern web technologies such as Nuxt.js and Tailwind CSS, providing a responsive and visually appealing user experience. Google Tag Manager is used for analytics and marketing tracking. The site structure is clear with well-organized navigation and SEO-friendly metadata. Performance is moderate, with room for optimization in image loading and script management. Accessibility is basic but functional. The absence of a traditional CMS suggests a custom or headless approach, which can offer flexibility but requires ongoing technical maintenance. Hosting details are not explicitly identified, limiting infrastructure insights. Overall, the technical implementation supports the business needs effectively but could benefit from performance tuning and enhanced accessibility compliance.
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.
