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

Dockerill Group is a well-established construction services provider based in Cambridge, UK, specializing in groundwork, demolition, recycling, and volumetric concrete. The company serves clients across East Anglia and London, positioning itself as a leading regional supplier with a strong reputation and a comprehensive service offering including its own transport division and recycling yard. The website reflects a professional business with clear service descriptions, client case studies, and contact information. Technically, the site uses modern web technologies such as Google Analytics, jQuery, and JSON-LD structured data, and is mobile optimized with good SEO practices. However, the absence of WHOIS registration data and security headers indicates areas for improvement in transparency and security posture. Privacy compliance is well addressed with clear policies and cookie consent mechanisms. Overall, the site presents a credible business but would benefit from enhanced security measures and WHOIS transparency.

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

5 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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

  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

  3. 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';…

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 · found on this site
  • 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

The Dockerill Group operates in the construction and transportation sectors, targeting construction industry clients requiring groundwork, demolition, and recycling services. The business model includes direct service delivery supported by a specialized transport fleet and recycling operations, indicating vertical integration. The company has a medium size profile, founded in 1983, with a growing market presence supported by client logos and case studies. The website's partnership with Brown & Brown for site development suggests a professional digital ecosystem. Revenue streams likely derive from construction contracts and recycling services. The company maintains active social media channels, enhancing its market visibility and client engagement.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and a cookie consent mechanism in place. However, no explicit security headers (such as CSP, HSTS, or X-Frame-Options) were detected, which could expose the site to certain web-based attacks. There is no visible security policy or incident response information, which limits transparency regarding security governance. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party analytics scripts requires ongoing monitoring to mitigate supply chain risks. Overall, the security maturity is moderate but could be improved by implementing recommended headers, publishing security policies, and enhancing incident response readiness.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Verify and update WHOIS registration details to ensure domain legitimacy and improve trustworthiness.
  4. Conduct regular security audits of third-party scripts and dependencies to mitigate supply chain vulnerabilities.
  5. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS, and JavaScript, leveraging jQuery and Google Analytics for functionality and tracking. It uses Google Fonts for typography and implements JSON-LD structured data for SEO and rich snippets. The site is responsive and mobile-friendly with adaptive images and layout adjustments for various screen sizes. Performance is moderate with no major issues detected, though optimization opportunities exist. No CMS or hosting provider information was identified from the source. The site includes a cookie consent banner with an AJAX-based consent mechanism, indicating some level of technical sophistication in privacy compliance. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and performance tuning.
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.
