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

Miller Insurance is a leading specialist broking and reinsurance firm operating primarily in the UK and international markets, including Lloyd's. The company offers a broad range of insurance products and services targeting corporate and private clients across multiple sectors such as energy, construction, and transport. Their website reflects a mature digital presence with professional design, clear navigation, and comprehensive content that supports their market position as industry leaders. Technically, the website employs modern JavaScript frameworks, integrates multiple analytics and advertising tools, and implements GDPR-compliant cookie consent mechanisms. The site is mobile-optimized and accessible, with good SEO practices. Security posture is strong with HTTPS enforcement and security headers, though there is room for improvement in publishing explicit security policies and incident response information. The absence of WHOIS data for the domain is a notable anomaly that impacts trustworthiness, suggesting either privacy protection or recent registration. Despite this, the professional presentation and comprehensive business information mitigate some concerns. Overall, the site demonstrates a solid security and compliance posture with minor gaps. Strategic recommendations include publishing a formal security policy, establishing clear incident response contacts, and adding a vulnerability disclosure program to enhance transparency and trust. Regular audits of third-party scripts and continued adherence to privacy regulations will further strengthen their security and compliance standing.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Miller Insurance holds a strong market position as a specialist insurance broker with a focus on reinsurance and niche insurance products. Their business model centers on providing tailored insurance solutions to corporate and private clients, leveraging Lloyd's market access. The company targets sectors such as energy, construction, and transport, indicating diversified revenue streams. The website content and navigation suggest a customer-centric approach with detailed product and sector information, supporting client acquisition and retention. The presence of GDPR-compliant privacy and cookie policies reflects regulatory awareness. The lack of visible parent or subsidiary relationships suggests an independent operation. The company’s digital ecosystem includes partnerships with major analytics and advertising platforms, indicating active marketing efforts.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly available security policy and incident response contact information represents a compliance gap and potential risk in incident handling transparency. The lack of a vulnerability disclosure program or security.txt file limits external security collaboration. Overall, the security maturity is good but could be enhanced by formalizing and publishing security governance documents and incident response procedures.

Recommendations

  1. Publish a detailed security policy page accessible from the website footer or about section.
  2. Provide clear incident response contact information, including abuse and security email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance monitoring and enforcement of security headers and SSL/TLS configurations to maintain best practices.

Notes

The website uses a modern JavaScript-based front-end with jQuery and integrates Google Tag Manager, Google Analytics, Bing Ads, and Vimeo Player API for analytics, advertising, and media playback. The presence of OneTrust indicates a robust cookie consent and privacy management framework. The site is well-structured with preloading of fonts and CSS for performance optimization. Mobile responsiveness and accessibility features are well implemented. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML content. Performance is moderate, with room for optimization in script loading and caching strategies. Overall, the technical infrastructure supports a professional and secure user experience.
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.
