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

heycar UK, operated by Mobility Trader UK Limited, is a well-established online marketplace specializing in quality checked used cars from trusted dealers across the United Kingdom. Founded in 2019, the company leverages a modern digital platform to provide car buyers with extensive listings, dealer access, car valuation tools, finance information, and expert reviews. The website demonstrates a strong market position within the UK automotive sector, targeting consumers seeking reliable used vehicles with transparent dealer relationships. The technical infrastructure is robust, utilizing Next.js and React frameworks hosted on AWS, integrating multiple third-party services such as Stripe for payments, Google Maps for location services, and advanced analytics platforms including Snowplow and Quantcast. The site is optimized for performance, mobile responsiveness, and accessibility, reflecting a mature digital presence. From a security perspective, heycar enforces HTTPS with a solid SSL configuration and employs a comprehensive cookie consent mechanism compliant with GDPR. While explicit security policies and incident response contacts are not publicly found, the domain registration is consistent and trustworthy, with no suspicious indicators. The absence of DNSSEC is a minor security gap. Overall, the security posture is strong but could be enhanced by publishing formal security and vulnerability disclosure policies. The overall risk assessment is low, with the website presenting a professional, secure, and user-friendly experience. Strategic recommendations include enabling DNSSEC, publishing privacy and security policies, and enhancing transparency around incident response 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

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • 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

  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

heycar operates as a medium-sized business in the transportation sector, focusing on the UK market. Its business model centers on connecting consumers with quality used cars through a curated dealer network, supported by value-added services such as car finance education and vehicle valuation. The company benefits from a strong brand presence, consistent marketing, and partnerships with payment and analytics providers. Growth indicators include a comprehensive digital platform and active social media engagement. The partnership ecosystem includes Carsale24 for car sales and InMobi for advertising. heycar's competitive advantage lies in its quality assurance and trusted dealer relationships, positioning it well against other online car marketplaces.

Security posture

heycar demonstrates a mature security posture with enforced HTTPS, clientTransferProhibited domain status, and a GDPR-compliant cookie consent framework. The use of modern web technologies and third-party integrations is managed securely, with no exposed sensitive data detected. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. DNSSEC is not enabled, which could improve DNS security. Overall, heycar's security practices align with industry standards but would benefit from enhanced transparency and formal documentation to support incident management and vulnerability reporting.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service accessible from the website footer.
  3. Develop and publish a security policy including incident response procedures and contact channels.
  4. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Explicitly configure and document security headers such as X-Frame-Options and X-Content-Type-Options.

Technical notes

Notes

The website is built on a modern React and Next.js stack, hosted on AWS infrastructure, ensuring scalability and performance. Integration with Stripe, Google Maps, Loqate, and Snowplow analytics indicates a sophisticated technical ecosystem. The site is well-optimized for mobile devices and accessibility, with comprehensive SEO metadata and structured data markup. The use of multiple CSS files and asynchronous JavaScript loading supports fast page rendering. Technical risks are minimal, though the absence of DNSSEC and explicit security headers could be addressed to reduce attack surface. Overall, the technical implementation reflects a high level of digital maturity suitable for a competitive online marketplace.
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.
