Optimised Decision Engine (ODE)

A revolutionary response to combat fraud and scams

Fraudulent activity presents a significant threat to the UK’s prosperity, national security and reputation. When it comes to combating fraud and scams, one of the biggest challenges is understanding how to minimise the number of false positives being generated whilst maintaining the desired level of fraud detection. 

Striking a balance between false and true positives remains a challenge for most firms. Inefficient or ineffective fraud strategies can lead to detrimental consequences, including a substantial negative impact on your customers and operations due to false positives, as well as increased losses resulting from missed fraud cases.

Fundamentally transform your fraud operations in a way never imagined before, with Sopra Steria's Fraud Optimised Decision Engine (ODE)

Most fraud detection providers enable you to improve your fraud management through authoring and editing your own rulesets, but often leave firms to do the hardest job themselves. 

ODE is different - It does the hard work for you

Instead, it optimises your current decision engine by replacing legacy rulesets in favour of a new auto-generated suite of optimised rulesets. 

Our solution:

  • Takes an automatic approach to optimisation through a suite of automatically generated rulesets.

  • Searches billions of permutations per day.

  • Frees up resources - SMEs only validate and select rulesets to be used to accommodate varying risk appetite.

  • Creates new rulesets each time, and take a fraction of the time to run.

  • Removes all bias related to legacy rulesets through the creation of new rulesets.
