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

Checkmate Fire is a UK-based leader in passive fire protection services, specializing in fire stopping, fire door inspections, installations, and repairs. The company boasts over 30 years of industry experience and maintains a large portfolio of buildings nationwide with a sizable specialist workforce. The website demonstrates a mature digital presence built on modern web technologies including Ruby on Rails, Hotwired Turbo, and Stimulus, complemented by Google Analytics and Tag Manager for marketing and tracking. Security posture is strong with HTTPS and CSRF protections, though explicit privacy and cookie policies are missing, which impacts 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

4 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  2. 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

  3. 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 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

The company operates as a service provider in the fire safety and passive fire protection sector, targeting commercial, residential, educational, healthcare, and industrial clients. Their business model includes consultancy, inspection, installation, maintenance, and training services. Market positioning is strong as one of the largest UK players in this niche, supported by certifications such as LPCB, Firas, BM Trada, and ISO. The company leverages partnerships and frameworks to enhance credibility. Growth indicators include extensive service offerings and a large operational footprint. The website's detailed sector and service pages indicate a strategic approach to customer segmentation and service delivery.

Security posture

The website employs HTTPS with valid SSL, uses CSRF tokens, and integrates security-conscious scripts. However, it lacks visible security headers like CSP or X-Frame-Options, and no incident response or vulnerability disclosure policies are published. No security.txt file is found. The site does not expose sensitive data or show signs of vulnerable libraries. Privacy compliance is partial due to missing explicit policies. Overall, the security posture is good but could be improved by adding formal policies and headers.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Implement and expose security headers such as Content-Security-Policy and X-Frame-Options.
  3. Add a vulnerability disclosure policy or security.txt file to improve transparency.
  4. Clarify domain registration details and ensure WHOIS data is accurate and consistent with business claims.
  5. Enhance cookie consent mechanisms to explicitly obtain user consent and document retention policies.

Technical notes

Notes

The website is built on a modern Ruby on Rails stack using Hotwired Turbo and Stimulus for dynamic interactions. It uses Glide.js for carousels and vanilla-cookieconsent for cookie management. Google Tag Manager and Analytics are integrated for marketing and tracking. The site is mobile responsive with good accessibility features and SEO optimization. Performance is moderate, with some lazy loading of images. The technical infrastructure is solid but could benefit from improved security headers and clearer privacy compliance implementations.
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.
