Client money and client files, handled with care.

Practices hold tax file numbers, bank details and financial records for every client, and move money on their instructions. That makes payment fraud and mailbox takeover the risks that matter most day to day.

Situations we help with

  • A client’s supplier “changes bank details”

    An email that looks like it comes from a client’s supplier asks you to update the account on an invoice you are about to pay on their behalf.

    What helps: Email protections that make impersonation harder, a call-back rule for any change of bank details, and staff who have practised spotting the request.

  • A partner’s mailbox is signed into from overseas

    Someone has the password for a partner’s Microsoft 365 account and has set up a rule forwarding client emails to an outside address.

    What helps: Multi-factor authentication for everyone, external forwarding blocked or alerted, and sign-in monitoring someone actually looks at.

  • A lost laptop with client files

    A staff laptop is left in a taxi with a year of working papers on it.

    What helps: Disk encryption on every device, files stored centrally rather than only on the laptop, and the ability to lock or wipe a managed device.

Depending on your business, privacy obligations such as the Notifiable Data Breaches scheme may apply when personal information is involved. Whether they apply to you, and what they require, is a question for your legal or compliance adviser — we can help you get the facts together for that conversation.
