Concrete Repairs Ltd (CRL) is a leading UK specialist contractor focused on concrete repair, refurbishment, and asset maintenance for buildings and infrastructure. With over 70 years of experience, CRL serves multiple sectors including highways, water, marine, nuclear, rail, and heritage, delivering engineering-led, sustainable solutions. The company maintains a strong market position supported by certifications such as ISO 44001 and Achilles UVDB, and a robust digital presence including social media and a comprehensive website. Technically, the website employs modern JavaScript libraries like MooTools, Google reCAPTCHA for form security, and integrates Google Maps and Lottie animations for enhanced user experience. The site is hosted with a reputable registrar and uses HTTPS with good SSL configuration, though security headers could be improved. The site is mobile-optimized and SEO-friendly, providing a professional and accessible user experience. From a security perspective, CRL demonstrates good practices including GDPR compliance, cookie consent mechanisms, and secure contact forms. No critical vulnerabilities or exposed sensitive data were detected. However, enhancements such as enabling DNSSEC, publishing incident response policies, and adding security headers would strengthen the security posture further. Overall, CRL's website reflects a mature, trustworthy business with a strong focus on quality, compliance, and customer engagement. The domain registration details align well with the business profile, supporting legitimacy. Strategic recommendations include improving security headers, formalizing incident response disclosures, and enhancing accessibility compliance to maintain leadership in digital maturity and security.

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. 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)

      • 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. 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

    • High

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

CRL operates as a specialist concrete repair and refurbishment contractor with a diversified portfolio across key infrastructure sectors. Its competitive advantage lies in technical expertise, long-standing client relationships, and comprehensive certifications. The business model focuses on delivering both principal contracting and specialist subcontracting services. Revenue streams likely derive from multi-sector projects including highways, water, marine, and nuclear infrastructure. The company targets infrastructure owners, asset managers, and construction clients seeking sustainable and innovative repair solutions. Growth indicators include expansion into Australia and continuous certification achievements. The partnership ecosystem includes industry accreditations and memberships, enhancing credibility and market reach.

Security posture

CRL exhibits a solid security maturity level with HTTPS enforcement, use of Google reCAPTCHA on forms, and cookie consent mechanisms aligned with GDPR. The absence of security headers and DNSSEC are areas for improvement. No exposed sensitive data or vulnerable libraries were detected. Compliance with GDPR is evident through clear privacy and cookie policies. Incident response and vulnerability disclosure policies are not publicly available, representing a compliance gap. The security culture is supported by certifications and audit successes (Achilles UVDB, RISQS). Overall, the security posture is good but can be enhanced by formalizing policies and technical controls.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  3. Publish an incident response plan and vulnerability disclosure policy to improve transparency and readiness.
  4. Conduct accessibility audits and improve compliance with WCAG standards to enhance user inclusivity.
  5. Regularly review and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a custom or proprietary CMS with a technology stack including MooTools JavaScript framework, Google reCAPTCHA for bot protection, Google Maps API for location services, and Lottie animations for interactive graphics. The site loads asynchronously for scripts, uses Google Fonts for typography, and integrates analytics via Google Analytics and Ahrefs. Performance is moderate with room for optimization. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Technical risks include lack of security headers and absence of DNSSEC, which could be addressed to improve security and trust.
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.
