Is Your Company Prepared for the New Generation of Fraud? See 7 Prevention Tactics You Can Automate

The era of PIX and instant transactions has brought unprecedented agility to businesses in Brazil. But that same speed has opened new avenues for fraudsters, who now operate with an alarming level of sophistication. Manual prevention processes or legacy systems simply cannot keep up.

When risk analysis depends on human review or on “hard-coded” rules that take weeks to change, your company becomes vulnerable. The result? Financial losses, reputational damage, and worst of all, a breach of customer trust.

The good news is that the most effective defense against modern fraud is intelligent automation. A robust rules engine enables dynamic, real-time protection. Here are 7 essential tactics that CADS DIGITAL implements to protect its clients.

Robust Identity Verification (Real-Time KYC)

Customer onboarding is the main entry point for fraudsters. Automating document validation (CPF, CNPJ), checking credit bureaus and sanctions lists in seconds, and cross-referencing registration data to identify inconsistencies form the first line of defense—blocking fraudulent accounts before they even exist.

24/7 Transaction Monitoring

In the world of PIX, fraud analysis cannot wait. A rules engine monitors every transaction in real time, comparing it to the customer’s profile. A high-value purchase at an unusual time from a new device? The rule can trigger two-factor authentication or even proactively block the transaction.

Geolocation Analysis

If a customer makes a purchase in São Paulo and, two minutes later, attempts another in Ceará, something is wrong. Automated geolocation rules can identify these geographic impossibilities and flag the transaction as suspicious, preventing cloned card fraud.

Behavioral Deviation Detection

A rules engine learns each user’s patterns (average transaction value, frequency, common locations). When a sudden deviation is detected, the system can escalate the transaction’s risk level, protecting the customer from fraudulent activity.

Device Analysis (Device Fingerprinting)

Multiple login attempts from different devices within a short time? A new device attempting a high-risk transaction? Automation can detect and flag these patterns—classic indicators of an account takeover attempt.

Watchlist Screening

Your company must ensure it is not conducting business with individuals or entities listed on national or international sanctions lists. A rules engine automates this verification at every transaction or onboarding event, ensuring continuous compliance and avoiding regulatory risks.

Real-Time Data Enrichment

A single data point may not be enough. True intelligence comes from combining information. In milliseconds, the platform can query external data sources (credit bureaus, email/phone validation services) to enrich the transaction’s risk profile, enabling more precise and secure decisions.

How CADS and the Decisions Platform Bring These Tactics Together

Individually, each tactic is powerful. Together, orchestrated by a single platform, they create an almost impenetrable security mesh.

This is where CADS DIGITAL comes in. We use the Decisions platform to design and implement fraud prevention systems tailored to your business reality.
