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

Dyson Cars Ltd is a small, family-run used car dealership located in Waltham Abbey, Essex, UK. The company specializes in selling quality used vehicles with competitive pricing, offering finance options and extended warranties. Their market position is that of a trusted local dealer with a strong emphasis on customer service and positive customer feedback. The website is professionally designed, mobile-optimized, and includes structured data to enhance search engine visibility. Contact information and social media presence are clearly provided, supporting business credibility. Technically, the website uses a mix of established JavaScript libraries and plugins such as jQuery, noUiSlider, Select2, and Owl Carousel, built on the Car Dealer 5 CMS platform. The site loads with moderate performance and good mobile responsiveness. Security measures include HTTPS enforcement and Google reCAPTCHA on forms, along with a cookie consent banner indicating GDPR compliance. However, the absence of security headers and explicit security or incident response policies suggests room for improvement in security posture. The WHOIS lookup failed due to domain naming rule violations, resulting in no registrar or registration data available. Despite this, the website content and business details indicate a legitimate operation. No WAF or blocking mechanisms were detected, and the site is fully accessible. Overall, the site scores well on content quality, technical implementation, privacy compliance, and business credibility, but security posture and WHOIS transparency reduce the overall trust score. Strategic recommendations include implementing security headers, publishing clear security and incident response policies, regular updates of third-party libraries, and improving accessibility features. These steps will enhance the security posture and trustworthiness of the website and business.

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.

Priority findings

4 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 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';…

  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

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

Dyson Cars Ltd operates as a local used car dealership targeting customers in Essex and surrounding areas. Their competitive advantage lies in being a family-run business with personalized service, competitive pricing, and finance brokering capabilities authorized by the FCA. The business model focuses on retail sales of used vehicles, supplemented by finance and warranty offerings. Customer reviews on Google and Autotrader demonstrate strong customer satisfaction, supporting market reputation. The company leverages partnerships with platforms like Autotrader and Facebook for marketing and customer engagement. The website's integration with marketing tools and chat services indicates a focus on lead generation and customer interaction. Growth indicators include a diverse stock range and finance options. The absence of detailed financial or founding data limits deeper business intelligence insights.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect forms, indicating a baseline security posture. A cookie consent banner is present, supporting privacy compliance. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security maturity. No explicit security policies or incident response contacts are published, which may hinder transparency and preparedness. The WHOIS data is unavailable, which is a concern for domain legitimacy verification. No known vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses several third-party scripts, which should be regularly audited for security. Overall, the security posture is moderate but could be improved with additional controls and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish explicit security policy and incident response information on the website to improve transparency and preparedness.
  3. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  4. Enhance accessibility features to meet compliance standards and improve user experience.
  5. Investigate and resolve WHOIS data issues to improve domain registration transparency and trust.

Technical notes

Notes

The website is built on the Car Dealer 5 CMS platform, utilizing JavaScript libraries such as jQuery 2.2.4, noUiSlider for price range selection, Select2 for enhanced dropdowns, Owl Carousel for sliders, and FontAwesome for icons. Google reCAPTCHA v2 is implemented for spam protection on forms. The site uses lazy loading for images and includes a cookie consent mechanism. Performance is moderate with preloading of CSS and images. Mobile optimization is good with responsive design and media queries. SEO is supported by meta tags, Open Graph tags, and JSON-LD structured data. The site lacks advanced frameworks but is functional and user-friendly. Hosting provider details are not evident from the content. There is an opportunity to improve technical robustness by adding security headers and enhancing accessibility.
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.
