LeasePlan is a leading international vehicle leasing and fleet management company offering services primarily in the transportation sector. Their UK website targets businesses, SMEs, and personal lease customers, providing commercial van and car leasing solutions. The site is professionally designed with consistent branding and clear navigation, reflecting a mature digital presence. Technically, the website leverages modern technologies such as React, Datadog RUM for real user monitoring, Google Tag Manager for tag management, and OneTrust for cookie consent, indicating a well-maintained infrastructure. Security posture is strong with HTTPS enforced, comprehensive security headers, and no visible vulnerabilities or exposed sensitive data. Privacy compliance is robust, with clear privacy and cookie policies and GDPR adherence. However, the WHOIS data is unavailable, which is unusual but likely due to privacy protection services.

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. 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

  2. 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';…

  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

LeasePlan operates in the vehicle leasing and fleet management market, serving a broad audience including businesses and individual consumers. Their business model focuses on leasing vehicles to commercial and personal clients, supported by a strong partner ecosystem including Ayvens. The company maintains a large enterprise presence with a consistent brand image and comprehensive service offerings. The website's integration of analytics and consent management tools reflects a commitment to data-driven decision making and regulatory compliance. The absence of explicit security policies or vulnerability disclosure programs suggests areas for improvement in transparency and security culture. The partnership with Ayvens and use of reputable third-party services indicate a mature operational ecosystem.

Security posture

The website exhibits a strong security posture with HTTPS enforced and multiple security headers implemented, including Content Security Policy and Strict-Transport-Security. The use of OneTrust for cookie consent and Datadog for monitoring indicates proactive security and privacy management. No vulnerabilities or exposed sensitive information were detected in the HTML content. However, the lack of a publicly available security policy, incident response information, or vulnerability disclosure program limits transparency. The missing WHOIS data is a minor concern but likely due to privacy protection rather than malicious intent. Overall, the security maturity is good but could be enhanced by publishing formal security documentation and disclosure channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance frameworks.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance transparency by providing incident response contact information and procedures.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built using React, indicating a modern frontend framework. It uses Datadog RUM for real user monitoring and Google Tag Manager for managing analytics and marketing tags. Cookie consent is managed via OneTrust, a leading consent management platform. The site is served over HTTPS with strong security headers, suggesting good hosting and infrastructure practices. Performance appears moderate with optimizations for mobile devices and accessibility features in place. No CMS was explicitly detected, implying a custom or proprietary solution. Hosting provider details were not found in the HTML content. Overall, the technical infrastructure supports a secure, performant, and user-friendly experience but could benefit from explicit hosting and CMS transparency.
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.
