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

Tamdown is a well-established UK-based company specializing in infrastructure and groundworks services, with a strong market position supported by 50 years of experience. The website presents a professional image with clear descriptions of services, accreditations, and awards, targeting construction and development industry stakeholders. Technically, the site is built on WordPress with modern plugins such as Gravity Forms and Yoast SEO, hosted by GoDaddy, and employs HTTPS with a cookie consent mechanism, indicating a reasonable level of digital maturity. Security posture is adequate but could be improved by adding security headers and publishing formal security policies. Privacy compliance is basic, with a cookie banner present but no explicit privacy policy or terms of service detected in the provided content. Overall, the site is trustworthy and professional, though there is room for enhancement in privacy and security 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  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 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
  • 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

Tamdown operates in the real estate and construction sectors, providing essential infrastructure and groundworks services. Their business model focuses on delivering high-quality technical solutions with minimal community disruption. The company leverages accreditations and awards as trust signals and maintains a partnership ecosystem, including career services hosted on a related domain. The target audience includes developers, project managers, and construction firms. The website content and structure support lead generation and brand positioning, with clear calls to action and testimonials enhancing credibility.

Security posture

The website employs HTTPS and a cookie consent mechanism, demonstrating baseline security and privacy awareness. However, the absence of security headers and published security or incident response policies indicates moderate security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a vulnerability disclosure policy or security.txt file suggests limited readiness for coordinated vulnerability reporting. Overall, the security posture is adequate for a medium-sized business but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.
  3. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS using the Uncode theme and Gravity Forms plugin for form handling. It integrates third-party services such as Google Tag Manager, Google Analytics, Vimeo for video content, and CookieYes for cookie consent management. The hosting provider is GoDaddy.com, LLC. Performance is moderate with some optimizations like lazy loading and prefetching fonts. Mobile optimization is good, and SEO is supported by Yoast SEO plugin. The site uses jQuery and modern JavaScript libraries. Technical risks include missing security headers and lack of DNSSEC. Overall, the technical infrastructure is solid but could be improved with enhanced security configurations and accessibility compliance.
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.
