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

TMF Group is a leading global provider of administrative, compliance, and governance services, supporting companies across more than 80 countries. Their extensive service portfolio includes accounting, tax, payroll, capital markets, fund services, and ESG administration, targeting corporates, financial institutions, asset managers, private equity, and family offices. The company operates through a large global network of over 11,000 professionals in 125+ offices, serving major multinational clients including Fortune Global 500 and FTSE 100 companies. The website reflects a mature business model with a strong market position and comprehensive service offerings. Technically, the website employs modern technologies such as Microsoft Application Insights, Google Tag Manager, OneTrust for cookie consent, and Cloudflare for CDN services. The site is well-structured, mobile-optimized, and SEO-friendly, with good accessibility features. However, performance metrics were not available, limiting full assessment of speed. From a security perspective, the site implements multiple security headers including a strict Content Security Policy and HSTS. Cookies are set with secure and HttpOnly flags, and privacy compliance is well addressed with GDPR-aligned policies and consent mechanisms. The critical weakness is the absence of a valid SSL certificate and disabled TLS protocols, which severely undermines the security posture and user trust. This issue requires immediate remediation to enable HTTPS and secure communications. Overall, the website is professionally designed and content-rich, demonstrating high business credibility and privacy compliance. The main risk lies in the invalid SSL configuration, which impacts security scores and could expose users to risks. Strategic improvements in SSL/TLS deployment and continued transparency in security policies will enhance trust 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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

TMF Group's business intelligence reveals a strong global footprint with a diversified service portfolio tailored to complex multinational compliance and administrative needs. Their client base includes high-profile corporate and financial entities, indicating a premium market positioning. The company leverages technology platforms to deliver scalable and consistent services worldwide. Their marketing and analytics ecosystem is robust, utilizing multiple tracking and consent tools to optimize user engagement while maintaining privacy compliance. The absence of direct contact details on the homepage suggests a controlled communication channel, likely via enquiry forms, aligning with enterprise-grade client management. The WHOIS data supports legitimacy and consistency with the company's claimed global presence. Growth indicators include frequent publication of industry insights and case studies, reinforcing thought leadership. The company’s strategic focus on ESG and digital transformation services positions it well for evolving regulatory landscapes. Partnerships and integrations with major analytics and marketing platforms further enhance their operational capabilities. Overall, TMF Group demonstrates a mature, well-integrated business model with strong competitive advantages in global compliance services.

Security posture

The security posture of TMF Group's website is mixed. Positive aspects include comprehensive security headers such as Content Security Policy with nonce, X-Frame-Options, and X-Content-Type-Options, which mitigate common web vulnerabilities. The use of secure and HttpOnly cookies and a strict referrer policy further enhance security. Privacy compliance is robust, with GDPR-aligned policies and a OneTrust cookie consent mechanism. However, the critical deficiency is the lack of a valid SSL certificate and the absence of enabled TLS protocols, resulting in no HTTPS protection. This exposes users to potential interception and undermines trust. Additionally, no OCSP stapling or session resumption is configured, which could impact performance and security. No public incident response or vulnerability disclosure information is available, which limits transparency in security management. The overall security score is lowered significantly due to these SSL/TLS issues. Immediate remediation is required to deploy a valid certificate and enable modern TLS protocols to ensure secure communications and protect user data.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS and secure all communications.
  2. Enable TLS 1.2 or higher protocols and disable legacy insecure protocols to improve encryption standards.
  3. Implement OCSP stapling and session resumption to enhance SSL performance and security.
  4. Publish clear incident response and vulnerability disclosure policies to improve transparency and trust.
  5. Maintain and regularly update privacy and cookie consent mechanisms to ensure ongoing GDPR compliance.
Technical notes

Notes

The website is built on a modern technology stack including ASP.NET Core MVC inferred from cookie names, Microsoft Application Insights for telemetry, Google Tag Manager for tag management, and OneTrust for cookie consent. Hosting is via Cloudflare CDN, providing global distribution and DDoS protection. The site uses embedded Vimeo videos and integrates multiple third-party analytics and marketing tools such as Hotjar, Dynatrace, and Marketo. The HTML structure is valid and well-organized with responsive design and accessibility considerations. SEO is supported by canonical links, hreflang tags for multilingual support, and structured data in JSON-LD format describing the organization and website. However, performance data was not available, so speed and resource optimization could not be fully assessed. The main technical risk is the invalid SSL configuration, which must be addressed to avoid security and trust issues. Overall, the infrastructure is modern and scalable but requires SSL remediation and ongoing performance monitoring.
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.
