Financial institutions sit at a specific intersection of risk: they move money on request, and their staff are trained to be responsive to urgent client and executive communications. That combination makes them a preferred target for Business Email Compromise and wire-fraud schemes.
Why Financial Services Is Disproportionately Targeted
Attackers targeting banks and financial services firms are typically after one of two things: fraudulent wire transfers authorized through impersonated executive or client instructions, or credential access to move laterally into transaction systems. Both attack paths usually begin with a convincing email or SMS, not a technical exploit.
Behavioral Baselining for Payment Requests
Because financial institutions process a high volume of legitimate payment and account-change requests, static rules generate excessive false positives. Behavioral baselining — modeling typical requestors, typical amounts, and typical approval chains per client or department — allows anomalous requests (a new beneficiary account, an off-hours request, unusual urgency language) to be flagged without blocking routine business.
Vendor and Counterparty Risk
Financial institutions also work with a wide network of counterparties, custodians, and vendors — any of whom could be compromised and used as a trusted relay for fraud. Monitoring for reply-to mismatches, sudden changes in banking details, and communication-pattern deviations from known counterparties extends protection beyond the institution's own staff.
Deployment Considerations
DefenceNet has been piloting with financial institutions in Canada, and supports both API-based cloud deployment and fully on-prem, air-gapped deployment for organizations with strict data residency requirements.
Frequently Asked Questions
Does DefenceNet replace existing fraud detection systems at a bank?
No — it addresses the communication layer (email, SMS) where BEC and wire-fraud attempts typically originate, complementing rather than replacing transaction-monitoring and core-banking fraud systems.
Can this be deployed without sending data to the cloud?
Yes, an on-prem, air-gapped deployment option exists for organizations with strict data sovereignty requirements.
