Features
What Sentinel checks, and what it keeps.
01
Insider and payroll fraud
Payslip checks need a payroll feed: Xero Payroll or MYOB.

A vendor whose bank account or address matches a staff member’s.
Terminated employee still paid
Any payslip dated after the recorded termination date.
Shared bank accounts
Two or more employees or contacts paid into one account.
02
Invoice redirection and vendor checks
Holder-name match: Xero, and MYOB suppliers.

A vendor’s bank details changing, and any bill or payment within 7 days.
Registry verification
Vendor names checked against the ABR, UK Companies House and NZBN.
Account holder name match
The bank-account holder’s name compared with the verified legal name.
