How to Protect Your Business from Fraud: A Checklist for Online Payment Operators

Fraud isn’t just a “risk.” It’s a persistent operational threat to any business that accepts online payments. Ignoring it means losing money, customers, and reputation. That’s why it’s crucial to build protection not just in isolated areas, but systemically—across technologies, processes, and responsibilities.

Below is a practical checklist for businesses in fintech, e-commerce, iGaming, or digital services looking to reduce losses from fraudulent transactions.

What it means: Don’t rely on a single login factor. At minimum—password + SMS / push notification / biometrics.

What it delivers: Reduces account takeovers by over 80%.

Tranzzo in practice: 3D Secure 2.0, device fingerprinting, behavioral biometrics support.

What it means: Each transaction should be evaluated across dozens of parameters: IP address, geolocation, activity history, form fill speed, VPN/Proxy detection.

What it delivers: Identifies abnormal patterns and blocks fraud before funds are withdrawn.

Tranzzo in practice: 200+ transaction scoring criteria, rule-based filtering system, and AI analytics.

What it means: Block payments from countries where fraud levels exceed your acceptable threshold. Set limits by BIN, geography, and card types.

What it delivers: Immediate chargeback reduction and fraud blocking at the entry level.

What it means: IP addresses, devices, accounts, and cards previously involved in fraud should be automatically added to and processed by the system.

What it delivers: Fast detection of repeated attacks from known fraud actors.

Tranzzo in practice: Support for internal blacklists and global suspicious user tracking systems.

What it means: Require verification for every transaction. If supported, enable address verification (AVS) and CVV checks.

What it delivers: Reduces use of fake or stolen cards.

What it means: Automatically block users who attempt too many transactions in a short time.

What it delivers: Detects bots and card-testing attacks early.

What it means: Your operations team should have a dedicated interface for monitoring risks: transaction statuses, risk scores, suspicious patterns.

What it delivers: Enables real-time fraud response.

Tranzzo in practice: A dedicated Fraud Management Dashboard with blocking scenarios and automated actions.

What it means: Even automated systems need manual review. Are your rules effective? What can be optimized?

What it delivers: Updates filters to counter new attack types and reduces false positives.

What it means: Your provider shouldn’t just offer a gateway, but a platform with fraud detection tools at its core.

What it delivers: Lower losses, faster launch, and less manual work for your team.

Why Tranzzo: Tranzzo’s fraud module is part of the core infrastructure—not an add-on. You get a complete system for verification, filtering, and response without extra subscriptions.

What it means: Don’t limit fraud prevention to financial transactions. Fraud starts at account creation, form filling, and withdrawal method selection.

What it delivers: A proactive approach that reduces losses before fraud impacts your finances.

Fraud protection is not a compliance checkbox — it’s a process that must be integrated into your product and payment flow from day one. Companies that ignore fraud controls pay the price in losses, bank blocks, and user trust.

Tranzzo is more than just a payment processor. It’s infrastructure that empowers you to manage risk on every level — from API to back-office.
