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

Corbett Keeling Limited is a well-established, independent corporate finance advisory firm based in London, specializing in guiding private company owners through selling their business, raising capital, and acquisitions. With over 30 years of bespoke advice and a strong track record of 90% deal completion and 40% average uplift in sale value, the company positions itself as a trusted partner in the mid-market UK corporate finance sector. The website reflects a professional, client-focused approach with comprehensive service descriptions and client testimonials. Technically, the site is built on HubSpot CMS, leveraging modern marketing and analytics tools, though some legacy libraries like jQuery 1.11.2 are used. Security posture is good with HTTPS and privacy consent mechanisms, but could be improved with explicit security headers and updated libraries. The absence of WHOIS data for the domain introduces some uncertainty in domain legitimacy, but the FCA registration and professional content mitigate concerns. Overall, the website demonstrates strong business credibility, good technical implementation, and solid privacy compliance, making it a reliable digital presence for the firm.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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.

    • 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

The company targets owners of private UK companies valued between £10-150 million, offering tailored corporate finance advisory services. Its business model focuses on M&A advisory, capital raising, and acquisitions, emphasizing integrity and long-term client relationships. The firm leverages its family-owned status and founder's legacy to differentiate itself. The website's sector coverage includes consumer, financial services, healthcare, industrials, support services, and tech/media/telecoms, indicating a diversified client base. The presence of client logos and testimonials enhances trust and market positioning. The use of HubSpot CMS and integrated marketing tools suggests a mature digital marketing strategy. However, the lack of visible WHOIS data and domain age information warrants monitoring for domain ownership consistency.

Security posture

The website enforces HTTPS and uses sandboxed iframes for video content, reducing risk from embedded media. Privacy consent management is implemented, aligning with GDPR requirements. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not detected, representing an area for improvement. The use of an outdated jQuery version could pose vulnerabilities if not patched. No exposed sensitive data or obvious vulnerabilities were found in the HTML content. Incident response and security policy information are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security posture is good but can be strengthened with updated libraries, security headers, and published security policies.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Upgrade jQuery and other third-party libraries to their latest secure versions to mitigate known vulnerabilities.
  3. Publish an incident response policy or provide a dedicated security contact channel to improve transparency and preparedness.
  4. Enhance accessibility features to meet WCAG standards for broader user inclusivity.
  5. Regularly audit third-party scripts and integrations to ensure they comply with security and privacy best practices.

Technical notes

Notes

The website is built on HubSpot CMS, utilizing a combination of JavaScript libraries including jQuery 1.11.2, Font Awesome 4.7.0, Select2, and Slick Carousel for UI components. Google Analytics Universal and GA4 are integrated for analytics tracking, alongside HubSpot's own analytics and marketing tools. The site is mobile responsive with good SEO meta tags and structured data in JSON-LD format for videos, enhancing search engine visibility. Performance is moderate, with asynchronous loading of analytics and video embeds. Accessibility is basic but could be improved. The technical stack is modern but includes some legacy components that should be updated to reduce security risks and technical debt.
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.
