75/100

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

Marlow Gardner & Cooke Ltd is an established UK-based independent insurance brokerage with over 50 years of experience providing tailored insurance solutions for businesses and personal clients. The company offers a wide range of insurance products including commercial, personal, and specialist coverages, acting as an agent for clients with access to multiple insurers including Lloyd’s market. Their market position is supported by memberships in Brokerbility, BIBA, and Chartered Insurance status, reflecting a trusted and professional service. Technically, the website employs modern web technologies such as jQuery, Slick Carousel, and Google Analytics, with good mobile optimization and a professional design. Security is well addressed with HTTPS, HSTS, and multiple Content Security Policy headers, although some header consolidation and additional security headers could improve posture. Privacy compliance is supported by clear privacy and cookie policies with consent mechanisms. The security posture is strong with no visible vulnerabilities or exposed sensitive data. The WHOIS data is unavailable due to an invalid domain query (the domain with 'www.' prefix is not registered), but the website content and business information strongly indicate legitimacy. Overall, the site is professional, secure, and trustworthy, serving a clear business purpose. Recommendations include improving security header management, adding a security.txt file for vulnerability disclosure, and enhancing incident response contact visibility to further strengthen security culture and compliance.

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

      • 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

  • Security headers: did not complete in this scan.
  • 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

Marlow Gardner & Cooke operates as a small-sized, essential entity in the insurance brokerage sector within the UK. Their business model focuses on providing comprehensive insurance solutions for a broad range of business sectors and personal insurance needs. The company leverages its independent status and multiple insurer relationships to offer tailored products, differentiating from tied agents. Their long-standing presence and industry certifications provide competitive advantages. The target customers are local businesses and individuals seeking reliable insurance coverage. The company’s partnership with Brokerbility expands their market reach and access to competitive insurance products. The website content and structure reflect a mature business with steady growth and a focus on customer service.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and HSTS enabled, reducing risks of man-in-the-middle attacks. Multiple Content Security Policy headers restrict script sources and disallow form actions, enhancing protection against cross-site scripting and form-based attacks. No sensitive data exposure or vulnerable libraries were detected. However, the absence of a security.txt file and incident response contact details limits transparency for vulnerability reporting. Privacy policies and cookie consent mechanisms indicate GDPR awareness. Overall, the security measures align well with industry best practices for a small insurance brokerage, though some header improvements and formal incident response processes are recommended.

Recommendations

  1. Consolidate and optimize Content Security Policy headers into a single comprehensive policy.
  2. Add additional security headers such as Referrer-Policy and X-Content-Type-Options to enhance security.
  3. Implement a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  4. Increase visibility of incident response contacts or abuse reporting channels on the website.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries including jQuery 3.3.1, Slick Carousel, and Owl Carousel for UI components and interactivity. Google Analytics and Google Tag Manager are employed for user behavior tracking. The site is built with standard HTML5 and CSS3, with responsive design elements for mobile optimization. No CMS or hosting provider information is explicitly detected. Performance is moderate with asynchronous loading of analytics scripts. Accessibility features are basic but present. SEO is supported by meta tags and structured navigation. Technical debt appears low, but improvements in security header management and formal CMS or platform identification could enhance maintainability and security.
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.
