Guardian Analytics Inc. said it will launch an outsourced fraud prevention service Wednesday that will help financial institutions meet new Federal Financial Institutions Examination Council guidelines.

Those guidelines, released June 29, require banks to have a layered approach to security as well as continuous risk assessments. Banks must also protect security at the transaction level.

A chief concern for financial institutions, Guardian said, is that it may take too much time and is too costly to do ongoing account monitoring and behavior analysis, as the FFIEC guidelines now mandate.

Guardian's service will include help from its on-staff fraud analysts who can help financial institutions assess fraud alerts, flag high-risk events and activity, including unusual payments that may require internal review. The analysts would help keep unauthorized wire, automated clearing house and bill-payment transactions from leaving the institution, Guardian said.

The service will complement Guardian's automated fraud prevention platform FraudMap. Guardian is in Los Altos, Calif.
