Adaptive Antifraud 4kst

The new generation of anti-fraud with 4kst Adaptive AI technology
that chases the fraudster.

The only one that keeps up with the speed of the fraudsters.

Fraud patterns change at a much faster rate than traditional anti-fraud models can detect. Fraudsters take advantage of this and generate new strategies all the time, causing increased friction with customers and huge financial losses for institutions.

4kst Adaptive Anti-Fraud models are incremental and adaptive—they aren’t limited to historical data. They continuously learn as new types of fraud emerge. Even if a fraudster changes their strategy, the 4kst Adaptive Anti-Fraud model is ready to identify them.

Benefits

4kst Adaptive Anti-Fraud Models are highly accurate because they don't lose their relevance, even in highly dynamic and unpredictable environments.

Real-time detection of fraudulent transactions

The 4kst Transactional Anti-Fraud Model is fed back with new frauds in real time and allows fraudsters to be identified more quickly, regardless of special customer performance conditions.

More secure credit origination

The 4kst Anti-Fraud Model for Origination is updated in real time with information on new fraud cases, thereby ensuring greater reliability for card issuance, account opening, insurance, and other services.

Reduced friction with customers

Testimonials from those who have chosen 4kst

What our clients say about their results with 4kst.

We were extremely surprised by the figures

"The results were so good that I was suspicious, but I checked and they were right: defaults went from 33% to 13% in one market, from 37% to 19% in another. I don't know anyone who does it the way 4kst does, with this degree of personalization and evolution."

Relationship and Customer Experience Manager

VOX
4kst gives me the exact remedy for my illness

"The score isn't off-the-shelf, it's personalized, thought out and specific. The model is developed using our data and not just market data. It's more niche. 4kst gives me the exact remedy for my illness. It is 4kst that is leading to a reduction in our default rates. We've already achieved a 30% reduction. To improve this figure we need to cut credit, but we can't make the business unviable."

Financial Management

Todescredi
The 4kst model brought personalized decision-making

"We used to do the analysis manually. My pain was to have a robust score that took into account all our particularities: my portfolio, the history of clients and their risk ranking, where I am economically inserted, the 9 companies in the group and the various products involved. The 4kst model provided personalized decision-making, which was very important!"
