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

Mason Ltd is a small UK-based construction and building maintenance company with over 20 years of experience, offering services ranging from domestic to commercial projects including joinery, roofing, and local authority contracts. The website presents basic but relevant content focused on their services and client testimonials, targeting local clients in the construction sector. Technically, the website uses standard HTML, CSS, and JavaScript with Google Analytics and Cloudflare Insights for tracking, but lacks modern CMS or frameworks and shows limited mobile optimization and accessibility features. Security posture is weak due to absence of HTTPS enforcement, missing security headers, and lack of privacy or cookie policies, which also impacts GDPR compliance. The WHOIS data is unavailable due to a domain registration error from Nominet, raising concerns about domain legitimacy despite the website being active and professional in appearance. Overall, the website scores moderately on business credibility but low on security and privacy compliance, indicating areas for improvement.

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

8 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Mason Ltd operates as a local building contractor with a focus on quality workmanship and a broad range of construction services. Their market position is that of an established small business with a loyal client base, supported by testimonials. The business model is service-oriented, targeting both domestic and commercial sectors including local authorities. Revenue streams likely come from project contracts and maintenance services. The website lacks digital maturity with no evident partnerships or subsidiaries and minimal online presence beyond basic contact information. Growth indicators and strategic partnerships are not visible from the website content.

Security posture

The current security posture is basic and insufficient for modern standards. The absence of HTTPS enforcement and security headers exposes the site to potential interception and attacks. No privacy or cookie policies are present, indicating non-compliance with GDPR. No incident response or vulnerability disclosure information is provided. Tracking via Google Analytics and Cloudflare Insights is implemented without visible user consent mechanisms. The lack of contact emails and secure forms limits secure communication channels. Overall, the security culture appears minimal, with significant gaps in compliance and best practices.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add comprehensive privacy and cookie policies with clear GDPR compliance statements and user consent mechanisms.
  3. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  4. Provide clear and secure contact methods including company email addresses and secure contact forms with input validation.
  5. Improve website mobile responsiveness and accessibility to enhance user experience and compliance.

Technical notes

Notes

The website is built on basic HTML and CSS with JavaScript for analytics tracking. It lacks modern CMS or frameworks and shows signs of dated design and limited mobile optimization. Hosting appears to be behind Cloudflare, providing some performance and security benefits, but no advanced technical features or automation are evident. Performance is moderate but could be improved with modern techniques. The absence of structured data and SEO optimization limits search engine visibility. Technical debt is present due to outdated design and missing security features, posing risks to business operations and user 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.
