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

Marshall Construction is a well-established, family-managed construction and civil engineering company based in central Scotland, operating since 1983. The company employs approximately 200 skilled staff and manages projects ranging from small maintenance contracts to large developments exceeding £50 million. Their market position as a foremost independent building contractor in Scotland is supported by a strong reputation for quality and reliability. The website reflects a professional business model focused on direct employment of tradespeople and in-house management expertise. Technically, the website is built on WordPress using the Divi theme, incorporating modern web technologies such as jQuery, Google Fonts, and Cloudflare Turnstile for bot protection. The site is mobile-optimized, SEO-friendly, and integrates Google Analytics for visitor insights. Performance is moderate with good accessibility and navigation clarity. From a security perspective, the site enforces HTTPS and uses Cloudflare's Turnstile captcha to protect forms. GDPR compliance is evident through cookie consent mechanisms and privacy policies. However, there is room for improvement in security headers, incident response disclosures, and vulnerability disclosure policies. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website presents a low-risk profile with strong business credibility and good privacy compliance. Strategic recommendations include enhancing security headers, publishing security policies, and improving accessibility features to further strengthen trust and compliance.

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

3 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. 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 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
  • 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

Marshall Construction operates in the real estate and construction sectors, targeting clients in Scotland seeking high-quality building and civil engineering services. Their competitive advantage lies in their long-standing family management, direct employment of skilled tradespeople, and capability to handle large-scale projects. Revenue streams are primarily from construction contracts and specialized divisions such as roofing, scaffolding, and plant services. The company maintains a strong partnership ecosystem, including LinkedIn for professional networking. Growth indicators include a turnover exceeding £65 million and projects valued up to £50 million. The website content and structure support a professional and trustworthy market presence.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement and bot protection via Cloudflare Turnstile. GDPR compliance is well implemented with cookie consent banners and detailed privacy policies. However, the absence of security headers like Content-Security-Policy and lack of publicly available incident response or vulnerability disclosure policies represent gaps. No signs of exposed credentials, malware, or phishing were found. The security score is good but could be improved by adopting recognized frameworks such as ISO 27001 and publishing related policies. Incident response readiness and security culture indicators are not publicly visible, suggesting an opportunity for transparency enhancement.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and preparedness.
  3. Create and maintain a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  4. Consider obtaining and displaying recognized security certifications such as ISO 27001 to boost trust.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Divi theme and several popular plugins including Contact Form 7 and GDPR Cookie Compliance. It leverages Cloudflare services for CDN and bot mitigation. The tech stack includes jQuery, Google Fonts, and slick carousel libraries, supporting a responsive and interactive user experience. Performance is moderate with room for optimization. SEO is well addressed with Rank Math plugin and proper meta tags. Accessibility is basic and could be improved. No outdated or vulnerable libraries were detected. The hosting provider is not explicitly identified but Cloudflare presence suggests a robust infrastructure.
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.
