Masternaut Limited · Transportation · United Kingdom

High risk. 4 critical or high findings in GDPR outside view and SSL/TLS.

Security score

47/100

Risk levelHigh

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

Masternaut Limited operates as a leading UK provider of fleet telematics and tracking solutions, now branded under MICHELIN Connected Fleet. The company targets fleet operators seeking to optimize operations and reduce costs, offering telematics systems and fleet management services. The website reflects a professional B2B business model with a strong market position in transportation technology. Technically, the site is built on HubSpot CMS, leveraging modern marketing and analytics tools, but suffers from critical SSL certificate issues that undermine HTTPS security. Security headers are present but cannot compensate for the lack of a valid SSL certificate. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Contact information is available via phone and a contact form, but no explicit security or incident response policies are published. Overall, the site is functional and professional but requires urgent remediation of SSL and privacy compliance gaps.

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. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Masternaut's market positioning as a MICHELIN Connected Fleet brand provides competitive advantage through brand recognition and integration with Michelin's advanced fleet management services. The business model focuses on SaaS and hardware telematics solutions for fleet operators, emphasizing cost savings and operational efficiency. The website supports multiple languages, indicating a pan-European reach. The use of HubSpot CMS and marketing automation tools suggests a mature digital marketing strategy. However, incomplete DNS records and SSL misconfigurations may impact customer trust and SEO. The company maintains a LinkedIn presence but lacks visible email contacts or extensive social media engagement. No certifications or security policies are publicly disclosed, which could be improved to enhance credibility.

Security posture

The security posture is weakened by the absence of a valid SSL certificate and lack of modern TLS protocol support, exposing users to potential data interception risks. While security headers such as HSTS, CSP, and X-Frame-Options are implemented, their effectiveness is limited without proper HTTPS. No cookie consent or explicit GDPR compliance mechanisms are evident, raising privacy concerns. The site uses secure forms hosted via HubSpot but does not publish incident response or security policies. DNS records are missing or misconfigured, which could affect domain resolution and security. Overall, the site demonstrates basic security hygiene but requires significant improvements to meet modern security standards and regulatory compliance.

Recommendations

  1. Immediately resolve SSL certificate issues to enable valid HTTPS and modern TLS protocols.
  2. Implement a cookie consent banner/mechanism to comply with GDPR and enhance user privacy transparency.
  3. Publish a dedicated security policy and incident response contact information to improve trust and compliance.
  4. Correct DNS records to ensure proper domain resolution and reduce potential security risks.
  5. Enhance accessibility and navigation clarity to improve user experience and SEO.
Technical notes

Notes

The website is hosted behind Cloudflare and built on HubSpot CMS, utilizing jQuery, Slick Carousel, and Google Analytics with a cookieless client ID hashing method. The site is mobile optimized with responsive design and basic accessibility features. Performance metrics are unavailable, but the presence of lazy loading and CDN usage suggests moderate optimization. However, the invalid SSL certificate and missing DNS records represent significant technical debt and risk. The site uses multiple external resources from trusted domains but lacks structured data markup (JSON-LD) which could improve SEO. Overall, the technical infrastructure is modern but requires remediation of critical security and DNS issues.
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.
