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

GB Construction Supplies Ltd is a UK-based specialist distributor of external building materials with over 25 years of industry experience. The company targets private and commercial developers, builders, architects, and contractors, offering a comprehensive range of products including bricks, arches, specials, semi dry/wet cast stonework, natural and reconstituted stone, limestone, false chimneys, and lightweight stone. The business positions itself as a leading specialist distributor in the UK construction materials market, supported by trust indicators such as Constructionline membership and company registration details. Technically, the website is built on WordPress 5.9.13 with a modern tech stack including Bootstrap, FontAwesome, and Revolution Slider. The site is mobile-optimized with good SEO practices and uses Google Analytics for visitor tracking. Performance is moderate, and accessibility is basic but functional. Security posture is decent with HTTPS enforced and no exposed sensitive data, though security headers are missing and no explicit incident response or security policies are published. The WHOIS data is unavailable due to a domain registration error reported by Nominet UK, indicating the domain name contravenes naming rules. This inconsistency lowers the trustworthiness of the domain registration but does not directly contradict the legitimacy of the business as presented on the website. Privacy compliance is partial with a privacy policy present but no cookie consent mechanism. Overall, the website is professional and trustworthy from a business and content perspective but would benefit from improved security headers, enhanced privacy compliance, and resolution of domain registration inconsistencies to strengthen its security posture and trustworthiness.

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

7 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. 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  4. 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

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

GB Construction Supplies operates as a specialist distributor in the UK construction sector, focusing on external building materials. The company leverages relationships with leading manufacturers and quarries across the UK and Europe to supply a wide product range. Its business model centers on B2B distribution to developers, builders, architects, and contractors. The presence of a testimonials page and Constructionline membership indicates a focus on credibility and quality assurance. The company appears medium-sized with a well-established market presence. The website content and structure support a professional image, aiding customer trust and engagement. No parent or subsidiary companies are identified, suggesting an independent operation. The company uses digital marketing tools like Google Analytics and maintains a responsive website to support customer acquisition and retention.

Security posture

The website enforces HTTPS, ensuring encrypted communication. However, it lacks important security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No evidence of exposed sensitive data or vulnerable libraries was found. The contact form uses a reputable WordPress plugin with API integration, suggesting secure data handling. There is no published security policy or incident response information, which could hinder transparency and preparedness. Cookie consent mechanisms are absent, indicating partial GDPR compliance. Overall, the security posture is moderate but can be improved by implementing recommended headers, formalizing security policies, and enhancing privacy compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common attacks.
  2. Add a cookie consent banner and mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish a clear security policy and incident response plan with dedicated contact channels to improve trust and preparedness.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and maintain security.
  5. Resolve domain registration inconsistencies by verifying domain WHOIS data and ensuring compliance with Nominet UK naming rules.

Technical notes

Notes

The website is built on a WordPress CMS platform version 5.9.13, utilizing popular plugins such as Yoast SEO for search optimization, Revolution Slider for dynamic content display, and Contact Form 7 for user inquiries. The front-end uses Bootstrap 3.3.6 and FontAwesome 4.5.0 for styling and icons. JavaScript libraries include jQuery 3.6.0 and related migration scripts. Google Tag Manager and Google Analytics are integrated for tracking and marketing insights. The site is responsive and mobile-optimized with moderate performance. Accessibility features are basic, with room for improvement. No hosting provider information is explicitly detected. The technical stack is modern but would benefit from enhanced security configurations and performance optimizations.
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.
