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

Cellhire Ltd. is a medium-sized UK-based telecommunications company specializing in IoT solutions, mobile communications, eSIM, and data connectivity services targeted primarily at enterprise clients and indirect partners worldwide. The company positions itself as a leading global telecoms provider with a strong focus on innovation and customer-centric connectivity solutions. Their website reflects a professional and modern digital presence, showcasing multiple industry awards and a comprehensive portfolio of services including wholesale connectivity and satellite solutions. Technically, the website is built on modern frameworks such as Next.js and React, leveraging advanced analytics and marketing tools like Google Analytics, Bing Ads, and Demandbase. The site is well-optimized for performance, mobile responsiveness, and accessibility, with a robust cookie consent mechanism ensuring GDPR compliance. Security best practices are observed, including HTTPS enforcement and security headers, though explicit security policy and incident response information are not publicly detailed. The security posture is strong with no visible vulnerabilities or exposed sensitive data. However, the absence of WHOIS data for the domain raises some concerns about domain registration transparency, which slightly impacts the overall trust score. Despite this, the professional business presentation and consistent branding support the legitimacy of the company. Strategic recommendations include publishing a dedicated security policy, vulnerability disclosure program, and incident response contacts to enhance trust and compliance. Overall, Cellhire demonstrates a mature digital infrastructure and a solid market position in the telecommunications and IoT sectors, with room for improvement in transparency and security communication to stakeholders.

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

1 finding 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

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

Their business model includes direct service provision and wholesale partnerships, supported by dedicated portals for partners and SIM management. The company leverages industry awards and recognitions to strengthen market credibility and attract new clients.

Security posture

Cellhire’s website employs strong security measures including HTTPS, modern security headers, and a detailed cookie consent framework aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive information were detected in the website content. However, the lack of a publicly accessible security policy, incident response information, and vulnerability disclosure program suggests areas for improvement in transparency and readiness. The use of multiple third-party analytics and marketing scripts necessitates ongoing monitoring to mitigate supply chain risks. Overall, the security maturity level is good, but enhancing communication about security practices and incident handling would improve stakeholder confidence and compliance posture.

Recommendations

  1. Publish a comprehensive security policy page detailing security controls and practices.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Disclose Data Protection Officer contact information to enhance GDPR compliance transparency.
  5. Regularly audit and update third-party scripts to minimize supply chain security risks.

Technical notes

Notes

The website is built using Next.js and React frameworks, indicating a modern and scalable architecture. It integrates multiple third-party services for analytics, marketing, and consent management, including Google Analytics, Bing Ads, Lead Forensics, Microsoft Clarity, CookieYes, and Demandbase. The site demonstrates fast loading times, excellent mobile optimization, and good accessibility features. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. No CMS is explicitly detected, suggesting a custom or headless CMS approach. Hosting provider details are not evident from the content. The technical stack supports a professional and user-friendly experience with minimal technical debt visible.
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.
