Protect the revenue you fought to earn.
Kandral helps high-risk and grey-market operators shut down fraud, abuse, and chargebacks before they drain the bottom line. We turn payment risk from a cost centre into a controlled, measurable edge.
Built for operators the banks and generic providers say no to.
Fraud and abuse are business problems, not just technical ones.
We sit on the operator's side of the table. Every recommendation we make is judged on one thing: does it protect revenue without strangling the customers you actually want?
Revenue-first
We optimise for approved good transactions, not just blocked bad ones. False declines cost more than most fraud.
Signal, not noise
Real-time risk scoring and layered detection tuned to your traffic, your customers, and your margins.
Built for high-risk
We specialise in the verticals traditional providers avoid — where the abuse is smarter and the stakes are higher.
Four fronts. One goal: keep your money.
Each engagement is scoped to your stack and your threat model. Here's where we go to work.
Fraud Detection & Prevention
Real-time transaction risk scoring, card-testing detection, and interception of stolen-card and payment fraud before it settles.
Waste & Abuse Prevention
Stop promo, refund, free-trial, and bonus abuse, multi-accounting, and reseller and arbitrage exploitation of your offers.
Anti-VPN, Proxy & Bot Defence
Detect VPNs, proxies, and datacentre IPs, fingerprint devices, and mitigate location-spoofing and automated bot traffic.
Chargeback & Dispute Protection
Prevention, representment, and dispute mitigation — plus chargeback-ratio management to keep your accounts in good standing.
Layered defence, tuned to your traffic.
No single rule stops a determined attacker. We build defence in depth — scoring, fingerprinting, network intelligence, and dispute strategy working together — then tune every layer against your real data so legitimate customers never feel it.
- Threat-model review of your checkout and payment flow
- Risk-scoring and rules calibrated to your margins
- Ongoing tuning as attackers adapt
- Clear reporting tied to revenue, not vanity metrics
Questions operators ask us first.
Do you work with high-risk and grey-market businesses?
Yes — that's our focus. We specialise in the verticals traditional processors and consultants avoid, where fraud and abuse are more sophisticated and the margin for error is thinner.
Do you replace my payment provider or fraud tools?
No. We're consultants, not a processor. We work alongside your existing stack — tuning what you have, filling the gaps, and recommending tooling only where it genuinely moves the numbers.
How do you measure success?
Against revenue. Lower fraud losses and chargeback ratios, fewer abused promotions, and — just as importantly — fewer false declines on customers you want to keep.
Can you help lower our chargeback ratio quickly?
Often, yes. Prevention, representment, and dispute mitigation together typically bring ratios down and keep your merchant accounts in good standing. We'll be straight with you about what's realistic for your situation.
How do we start?
Email contact@kandral.com. We'll scope a short review of your payment flow and threat model, then tell you exactly where the risk — and the opportunity — sits.
