ZKX Helix FraudFighter™
Stop Fraud Before It Can Happen
Most fraud tools react after the damage is already done. ZKX Helix helps retailers, banks, and healthcare organizations verify trust at the moment fraud risk appears.
The Problem
Fraud Teams Are Still Being Asked to Guess
Account takeover, card-not-present fraud, new account fraud, promo abuse, and suspicious high-value purchases all share the same underlying problem: uncertainty. Is this the real customer? Is this the trusted device? Is this a legitimate transaction, or is an attacker using stolen credentials, a compromised account, or manipulated location data?
Most fraud prevention tools rely on risk scoring, behavioral signals, and post-transaction remediation. Those tools are useful, but they still leave retailers, banks, and healthcare organizations making expensive decisions with incomplete proof.
Add Proof at the Moment of Risk
Helix FraudFighter™ adds cryptographic identity proof to high-risk transactions, account activity, and customer workflows without slowing down every legitimate user.
When activity looks normal, the user can continue with little to no added friction. When the transaction, location, account behavior, or request pattern looks suspicious, Helix can trigger a verification check before fraud becomes a loss.
FraudFighter™ Benefits
- Stop account takeover fraud before it becomes a loss
- Adds proof where fraud risk is highest
- Reduces unnecessary customer friction
- Protects revenue, compliance, and customer trust
How Fraud Prevention Works With Helix
Helix helps organizations move from “this looks risky” to “we have stronger proof.” The result is a smarter fraud workflow that can protect revenue, reduce abuse, and improve confidence in high-risk decisions.
Step 1
A customer takes an action
A user logs in, makes a purchase, changes account details, initiates a transfer, or attempts another sensitive action.
Step 2
Risk is detected
The retailer, bank, or healthcare system identifies suspicious behavior, such as unusual location, device mismatch, account change, high transaction value, or abnormal activity.
Step 3
Helix triggers verification
Instead of blocking the user outright or allowing the action based on a score alone, Helix prompts a verification check tied to the trusted user and device.
Step 4
Action is approved, denied, or stepped up
If trust is proven, the customer continues. If the proof fails or risk remains too high, the action can be blocked, escalated, or routed for review.

Built for Fraud Moments That Cost Real Money
Fraud prevention should not punish every legitimate customer. It should step in when the action is risky enough to deserve stronger proof.
Watch Fraud Prevention in Action
Our FraudFighter demo shows a common scenario: most transactions move forward normally, but suspicious activity triggers a verification check before the transaction is allowed to continue.
In the demo, the user’s activity appears risky because the purchase is coming from a different location than normal. Helix steps in at the right moment to verify trust without adding friction to every shopper.
What Is Fraud Really Costing You?
Fraud costs more than the transaction itself. Chargebacks, manual reviews, customer support, compliance exposure, lost inventory, and account recovery all add up.
ZKX can help your team evaluate where proof-based verification may reduce risk in your current fraud workflow.
