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

TC Group is a well-established UK-based accountancy and business advisory firm, ranked among the top 40 in the country. The company offers a comprehensive range of services including tax planning, corporate finance, wealth management, legal, HR, and mortgage advice. The recent merger with Bulley Davey expands their regional footprint in the East Midlands and East Anglia and introduces new service lines such as business recovery and insolvency. The website reflects a professional and mature business with clear branding and comprehensive service offerings. Technically, the site is built on WordPress with modern performance optimizations and security measures such as HTTPS and hCaptcha on forms. However, the absence of WHOIS domain registration data is a notable gap in transparency. Security policies and incident response contacts are not explicitly published, which could be improved. Overall, the website and business present a credible and trustworthy profile with room for enhanced security communication.

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. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. GDPR outside view

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

    • 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

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

TC Group operates a professional services business model focused on accountancy and advisory services across multiple UK regions. Their growth strategy includes mergers and acquisitions, as evidenced by the integration of Bulley Davey and other regional firms. The company targets SMEs and personal clients requiring financial, legal, and HR services. Their market position as a top 40 UK firm and diversified service portfolio provide competitive advantages. The presence of multiple regional offices and client login portals indicates a mature operational infrastructure. Marketing efforts include active social media engagement and newsletter subscriptions. The company maintains compliance with privacy regulations and uses modern web analytics tools. The lack of visible security policy and incident response details suggests an opportunity to strengthen trust and compliance posture.

Security posture

The website enforces HTTPS and uses hCaptcha to protect contact forms, indicating a baseline security posture. No sensitive data is exposed in the HTML, and no vulnerable libraries were detected. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies reduce the overall security maturity. The missing WHOIS data for the domain raises concerns about domain registration transparency. There is no evidence of incident response readiness or dedicated security contact channels. The security score is good but could be improved by implementing recommended headers, publishing security policies, enabling DNSSEC, and enhancing monitoring. Overall, the security posture is adequate for a professional services website but lacks advanced maturity indicators.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Enable DNSSEC for the domain to protect against DNS spoofing and improve domain security.
  4. Regularly audit and update third-party plugins and libraries to mitigate vulnerabilities.
  5. Enhance monitoring and alerting mechanisms for suspicious activities and potential breaches.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, WP Rocket for performance optimization, and Search & Filter Pro plugin for enhanced search functionality. It uses hCaptcha for bot protection on forms and Google Tag Manager for analytics and marketing. The site is mobile-optimized with responsive design and good accessibility features. Performance is enhanced by lazy loading scripts and images. SEO is well implemented with comprehensive meta tags, Open Graph, and JSON-LD structured data. Hosting provider details are not explicitly identified. The technical infrastructure supports a professional and scalable online presence with opportunities to improve security headers and domain registration transparency.
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.
