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

Grant Thornton International Ltd. operates as a global professional services network specializing in audit, tax, and advisory services. It serves privately held businesses, public interest entities, and public sector organizations, positioning itself as one of the largest independent accounting and consulting networks worldwide. The website reflects a mature enterprise with consistent branding and comprehensive service descriptions, targeting a professional audience in the finance sector. Technically, the site employs modern analytics and marketing technologies such as Google Analytics, Microsoft Clarity, Optimizely, and OneTrust for privacy compliance. The site is mobile-optimized and demonstrates good SEO and accessibility practices. Security-wise, the website enforces HTTPS and uses cookie consent mechanisms but lacks explicit security headers and published security policies or incident response information, which could be improved.

Overall, the site is professional, trustworthy, and compliant with GDPR, though it could enhance transparency around security and incident response.

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 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

Grant Thornton International Ltd. holds a strong market position as a global network of independent member firms providing professional services in audit, tax, and advisory. Its business model relies on a decentralized network structure, serving diverse sectors primarily in finance and public interest. The company leverages digital marketing and analytics tools to engage its target audience effectively. The absence of direct contact information on the homepage suggests a focus on directing users through structured channels or local member firms. The website's comprehensive privacy and cookie policies indicate a commitment to regulatory compliance. The firm’s global reach and enterprise size are evident, though specific founding year and subsidiaries are not disclosed in the analyzed content.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and a robust cookie consent framework managed by OneTrust. The use of Microsoft Application Insights indicates active telemetry and monitoring. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, which limits transparency and preparedness communication. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is adequate for a professional services website but could be strengthened by adopting additional security best practices and publishing relevant policies.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response page to improve transparency and user trust.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Provide clear and accessible contact information for security incidents and data protection inquiries.
  5. Regularly review and update third-party scripts and analytics tools to minimize potential vulnerabilities and ensure privacy compliance.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Google Analytics, Optimizely for experimentation, OneTrust for cookie consent management, and Microsoft Application Insights for telemetry. The site is well-optimized for mobile devices and demonstrates good SEO practices with appropriate meta tags and Open Graph metadata. Performance is moderate, likely influenced by multiple external scripts and tracking services. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not evident from the provided data. Overall, the technical infrastructure supports a professional and scalable web presence but could benefit from performance optimizations and enhanced security configurations.
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.
