THE PROBLEM

Block too much and you lose sales. Block too little and you absorb fraud.

Managing fraud with fixed PSP thresholds creates the same problem as fraud itself: lost revenue. Without your own rules, you are always making the wrong decision.

01

Fixed PSP rules

Each processor applies its own criteria. Without visibility into what is blocked or why. With multiple PSPs, each one decides differently.

02

False positives

A legitimate customer with a foreign card or high amount gets blocked. You lose the sale and the customer leaves with a bad experience.

03

Without operational autonomy

Any adjustment to the fraud rules must go through engineering or the processor. The team cannot react to a new pattern.

HOW IT WORKS

Your rules. Your criteria.
Built into the orchestration.

Full control over your payments, without a single line of code

Zru evaluates each transaction with a cumulative scoring system defined by you. The result not only determines if the payment is blocked, but also decides what happens next in the orchestration flow.

Define your strategy from the panel

Combine up to 42 predefined variables (amount, issuing country, BIN, IP, buyer history...) or add your own. Each rule adds or subtracts points from the total score. No code, no engineering tickets.

Zru scores each transaction in real time

Zru evaluates each transaction in real time

The engine evaluates all active rules and calculates a cumulative score. A frequent buyer with a foreign card might add risk points but subtract them due to a clean history; the system weighs the factors and does not block blindly.

The engine decides whether to authenticate in the background (frictionless) or trigger a challenge only when the risk justifies it.

The score triggers the correct action

Depending on the risk level: frictionless payment, 3DS challenge, or blocking. The score is just another variable within the orchestration flow, not a two-state traffic light.

Instant block from the activity section

You detect a fraudulent transaction on the panel and block the card, BIN, IP, device, or email with one click. Without setting up anything additional. Any subsequent attempt is automatically rejected.

Measure the impact of your rules

The statistics panel shows the evolution of your fraud rate and the volume of blocked transactions. Adjust your rules with data, not with intuition.

Strategies

Choose how to respond to the risk

There is no single correct answer to fraud. You define what happens in each risk bracket, and you can change it whenever you want, without touching any code.

3DS

LOW RISK

Frictionless approval, for trusted transactions

The payment flows without 3DS or interruptions. The buyer doesn't notice a thing. Repeat customers or those on a trusted list always take this path.

3DS

Without 3DS

54

MEDIUM risk

Proportional verification, for ambiguous transactions

The 3DS challenge is activated before processing. Neither blocked nor free-pass. The customer can complete the purchase by verifying their identity.

LOCKED

93

HIGH risk

Automatic block, for high-risk transactions

The transaction is rejected before reaching the processor. From the panel, you can block the item with a single click.

Frequently asked questions

Frequently asked questions

Does fraud scoring replace 3DS?

No, it decides when to apply it. The score evaluates risk before processing and determines what happens next: frictionless payment, a 3DS challenge or a block. They're two complementary layers, one decides and the other authenticates.

How is this different from my processor's fraud system?

It comes down to who decides. Your processor applies its own criteria and doesn't tell you what gets blocked or why. With Zru you define your rules, see the score behind every transaction and adjust your thresholds when a new pattern shows up.

That said, using your own rules doesn't stop your processor from applying its own on top: Zru's rules act first, on the transactions you decide to let through.
