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

Marks Tey Autospares Ltd is a small, established vehicle parts supplier based in Colchester, UK, with over 25 years of experience. The company offers a wide range of genuine vehicle parts and accessories, serving local customers through a physical store and an online sales channel. The website reflects a professional and consistent brand presence with clear contact information and social media links. Technically, the site uses modern JavaScript libraries and is hosted on a platform provided by Yell.com, with good mobile optimization and SEO practices. Security posture is solid with HTTPS and CAPTCHA on forms, though some security headers are missing and no explicit security policies are published. WHOIS data for the domain is unavailable due to a naming rules violation, which slightly reduces domain trustworthiness but does not detract from the business legitimacy as presented on the site.

NIS2 Art. 21(2)

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

3 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.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: mx.marksteyautospares.co.uk.cust.a.hostedemail.com

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

  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

  3. 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

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 business operates in the transportation sector, focusing on retail and wholesale of vehicle parts and accessories. It targets vehicle owners and automotive service providers in the Colchester area. The company leverages a local physical presence combined with online sales to reach customers. The partnership with Yell.com for website hosting and policy hosting indicates a reliance on third-party services for digital infrastructure. The company maintains active social media profiles and encourages customer reviews, enhancing trust and market presence. No evidence of subsidiaries or parent companies was found, indicating an independent small business model.

Security posture

The website demonstrates a moderate to good security posture with enforced HTTPS, use of CAPTCHA on contact forms, and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap. There is no published incident response or vulnerability disclosure policy, which could be improved to enhance transparency and preparedness. Privacy and cookie policies exist but are basic and hosted externally, with limited GDPR compliance indicators. Overall, the security maturity is adequate for a small business but could benefit from enhancements in policy transparency and technical controls.

Recommendations

  1. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the site against common web attacks.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and customer trust.
  3. Enhance privacy and cookie policies to explicitly address GDPR compliance and data retention practices.
  4. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  5. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built using Yell.com's multiscreensite platform, leveraging jQuery 3.7.0, skrollr for parallax effects, and Mapbox for map integration. It uses Snowplow Analytics for user tracking and Google Fonts for typography. The site is served over HTTPS with a valid SSL certificate and uses CDN-hosted resources for performance. Mobile optimization is good, with responsive design and viewport settings. Accessibility features are basic but present. SEO is supported by proper meta tags and Open Graph data. Performance is moderate, with some room for optimization in CSS and JavaScript loading. The technical stack is modern but relies heavily on third-party hosted scripts and services.
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.
