Professional services

Security for the firms that hold their clients’ affairs.

We test, harden and run the systems advisory, accounting and consulting firms keep client data in.

Professional services

The obligations in play.

An adviser holds a client’s financial position, identity documents and correspondence, usually in a Microsoft 365 tenant and a handful of cloud practice systems. One compromised inbox is enough to redirect a payment or expose a file.

AML/CTF tranche 2 adds program and due diligence obligations for accountants providing designated services, and larger clients now ask for evidence of controls before they share data.

  • Privacy Act 1988 and the APPs

    Client personal and financial information under the Australian Privacy Principles, with the Notifiable Data Breaches scheme behind it.

  • AML/CTF Act, tranche 2

    Accountants providing designated services have been reporting entities since 1 July 2026: programs, customer due diligence and records.

  • Tax Agent Services Act 2009

    The Code of Professional Conduct obliges registered tax and BAS agents to keep client information confidential.

  • Client security questionnaires

    Larger clients and government buyers ask advisers to evidence their controls before they share data.

What the sector is facing.

What we do

What you carry, and what we do about it.

  • Client files live in a Microsoft 365 tenant, one compromised inbox away from a redirected payment.

    We review and harden the tenant your firm signs in to: Conditional Access and MFA coverage, privileged roles, app consent and offboarding.

    Entra ID and Microsoft 365 review
  • Larger clients ask for evidence of your controls before they send the work.

    SMB1001 readiness turns the controls you run into a certificate on a public registry, and an Essential Eight assessment rates the hardening behind it.

    SMB1001 certification readiness
  • Portals, remote access and the website face the internet every day.

    We test the hosts you expose, verify and re-rate every finding, and hand back a remediation programme with a re-test.

    Penetration testing
  • The tenant, the devices and the accounts need running well, every week.

    Managed ICT runs Microsoft 365 tenants, devices and support, under the same practice that secures them.
