Industry Context
Why this matters for accounting firms.
The main risks for accounting firms are not only technical. They include careless spreadsheet sharing, weak access control, fake invoice requests, payroll data exposure, uncontrolled backups, and clients losing confidence because confidential financial information was mishandled.
Can staff download or share all client files without approval?
How are bank detail changes confirmed before payment?
Who can access payroll or tax files?
Can critical files be restored if a laptop or cloud account is lost?
Common risks
