SCENARIO

The challenges of transactional security

At Nexi, ensuring a secure and smooth payment experience is a top priority. Millions of transactions are processed every day, an amount that involves two significant challenges: the management of fraud, although statistically rare, must be impeccable to avoid negative impacts, and response times must be extraordinarily fast, in the order of milliseconds, so as not to compromise the user experience.

Added to this scenario are the transformations introduced by the regulatory environment of PSD2 in 2018, which required the implementation of strong authentication mechanisms (SCA - Strong Customer Authentication) and has expanded the information assets available on transactions. These developments have made a technologically advanced approach essential to guarantee the highest level of security without sacrificing the fluidity of payments.

The solution

AI and fraud intelligence to monitor payments

Traditional fraud detection methods are based on rule engines with different levels of complexity, developed by domain experts. This approach, as useful as it is, has two main limitations. On the one hand, the maintenance of these systems requires a consistent operational effort, with a constant need for manual updates to deal with new fraud scenarios. On the other hand, it typically has a significant incidence of false positives (genuine transactions that are incorrectly classified as suspected fraud), with a negative impact on the customer experience and less fluid processes.

To overcome these limitations, Nexi has collaborated with Data Reply to develop a fraud intelligence solution based on artificial intelligence.

This system, designed to monitor 3DS Full Secure transactions, has optimised the way in which Nexi manages payment security, maintaining an optimal balance between protection and service fluidity. The new solution is able to:

  • Leverage machine learning models to ensure accurate and easily interpretable analysis of transactions.

  • Evaluate suspicious transactions in milliseconds, while complying with stringent latency requirements.

  • Integrate a containerised architecture with Docker, making it lightweight, scalable and compatible with existing infrastructure

We innovate with AI to make every payment safer, faster and smoother: because trust is built, one transaction at a time.
