Fuzzy Logic represents expert knowledge

As the world's first fraud prevention system, RiskShield uses Fuzzy Logic – accepted as the best mathematical theory to represent (fuzzy) human expert knowledge. RiskShield thus offers your experts the possibility to feed the system with fraud-prevention rules in everyday language and with the aid of graphic editors. Fraud-prevention rules can thus be defined very easily, for example: „In the case of a relatively high amount of a transaction with a card from a problem region with a merchant who has already carried out more than two transactions on the same day with cards from the same problem region, reject the transaction and inform the merchant.“

Evaluation of historical data

RiskShield saves the typical transaction behaviour of card holders, merchants and possibly further historical profiles, and allows you to use these histories in fraud-prevention rules.

Extremely high real-time performance

The online authorisation system of a payment service provider receives the transaction inquiry and forwards this to the RiskShield server for a risk assessment. RiskShield responds to these inquiries in a matter of milliseconds.
Our customers report of throughputs of 2,200 transaction evaluations per second in peak times. RiskShield is thus one of the world's most efficient fraud prevention systems for cashless payments.

High transparency

Unlike most of the other fraud-prevention systems, RiskShield can also provide a reason for the risk assessment on request. Transactions rated as suspect or risky can be tracked separately by your staff using RiskShield Investigator. Extensive reporting functions are available to prepare statistics.

Short reaction times to new fraud patterns

Your fraud experts use the RiskShield client to evaluate new rules against new fraud patterns. The effects of new rules can initially be tested on the basis of older transaction data before they are set into production with only one click – with no downtime of the RiskShield decision server.

A wide variety of uses

RiskShield can also be used for fraud prevention and risk assessment in other fields, e.g. Internet banking, credit applications and to prevent internal fraud.
