The company provides a wide range of surface marking services including road marking, car park line marking, warehouse floor marking, and sports venue markings. They serve a diverse clientele including local authorities, businesses, and large commercial entities. The website reflects a professional and trustworthy business with multiple industry certifications and accreditations, positioning them as a leading service provider in their sector. Technically, the website is built on WordPress with a modern tech stack including jQuery, Google Analytics, Microsoft Clarity, and Google Tag Manager. The site is mobile optimized, has good SEO practices, and uses cookie consent mechanisms to comply with privacy regulations. Hosting and domain registration are consistent with a legitimate UK business, though DNSSEC is not enabled, and some security headers are missing. From a security perspective, the site uses HTTPS and implements cookie consent, but lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or exposed sensitive data were detected. The overall security posture is moderate with room for improvement in DNS security and HTTP headers. Overall, the website is safe, professional, and compliant with GDPR requirements. It effectively supports the business's credibility and market position. Strategic recommendations include enabling DNSSEC, adding security headers, publishing security and incident response policies, and implementing a vulnerability disclosure program to enhance 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

10 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. 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

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 company operates in the transportation sector specializing in surface and line marking services across the UK. Their business model focuses on contract-based service delivery to public and private sectors, including local authorities and large commercial clients. The presence of multiple certifications such as CHAS, IOSH, SPA, CSCS, and Safe Contractor indicates a strong compliance and safety culture, which is a competitive advantage. The company targets a broad audience from small landlords to large organizations, indicating scalability and flexibility. The website's client logos and case studies demonstrate a solid partnership ecosystem and market presence. Growth indicators include a well-maintained website with active marketing and analytics tools, suggesting ongoing business development efforts.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents potential areas of vulnerability. No incident response or security policy information is published, which could hinder effective communication during security events. The use of multiple third-party analytics and advertising scripts increases the attack surface but appears managed through consent mechanisms. There is no evidence of exposed sensitive data or vulnerable libraries in the HTML content. Overall, the security posture is adequate for the business type but would benefit from enhanced DNS security, HTTP headers, and published security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Implement security HTTP headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Regularly review and update third-party scripts and plugins to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using a combination of jQuery, Bootstrap, and various plugins such as Easy Fancybox and Kiwi Logo Carousel. It integrates multiple analytics and advertising platforms including Google Analytics, Google Tag Manager, Bing Ads, and Microsoft Clarity. The site is mobile responsive and optimized for SEO with proper meta tags and structured data (JSON-LD). Hosting is managed through GoDaddy with a domain age of over 12 years, indicating stability. Performance is moderate with room for optimization. Accessibility features are basic but present. The technical infrastructure supports the business needs effectively but could be enhanced with improved 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.
