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.
