our call
Start with FraudNet — highest vibe code, weakest moat.
FraudNet
Building a rule engine with MaxMind or Radar APIs takes a weekend, but you cannot replicate FraudNet's global network of shared fraud signals and device fingerprint intelligence. Without global transaction data across thousands of stores, custom AI models hallucinate or generate false positives that destroy legitimate conversion.
you can rebuild
- Rule-based transaction scoring engine (e.g., velocity checks, threshold limits)
- Order risk review dashboard and manual approval workflow
- Blacklisting and whitelisting by email, IP, shipping address, or BIN
- Basic geo-IP mismatch detection and address verification triggers
- Webhook alerts and automated order holding in Shopify or WooCommerce
what you lose
- Cross-merchant network intelligence tracking fraud rings across thousands of stores
- Proprietary device fingerprinting heuristics bypassing browser privacy protections
- Chargeback guarantee coverage options that shift financial liability away from you
- Real-time proxy, VPN, TOR, and residential botnet IP reputation databases
- Continuous machine learning model retrain cycles backed by global dispute feeds
real moats
- Cross-merchant consortium data linking malicious devices and emails across clients
- Proprietary device fingerprinting scripts resilient to modern privacy browsers
- Chargeback liability shifting and financial guarantee models
open source escape hatches
- Zen Engine MIT
- Grule Rule Engine Apache-2.0
- Apache Fineo / Open Threat Feeds Apache-2.0
Signifyd
You can build the device fingerprinting script, rules engine, and Shopify order-hold webhook with AI in a weekend. What you cannot build is the bank balance required to reimburse merchants when your algorithm misclassifies a $3,000 stolen-card order.
you can rebuild
- Order hold and manual review queue automation
- Device fingerprinting and session analytics collection
- Custom risk-scoring rules engine (IP velocity, address matching, order value limits)
- Webhook routing to Shopify, Magento, and WooCommerce for order cancellation
- Basic chargeback notification webhook listeners
what you lose
- 100% financial chargeback guarantee on approved orders
- Access to Signifyd's 10,000+ merchant global identity graph
- Automated 48-hour chargeback reimbursement payouts
- Third-party enterprise liability offloading for accounting audit compliance
- Dedicated human fraud analysts for manual order re-reviews
real moats
- Balance sheet reserves capable of liquidating millions in chargeback indemnifications monthly.
- Cross-merchant device and identity graph built over a decade across 10,000+ enterprise retailers.
- Direct integrations into card network early-warning feeds (Ethoca, Verifi, RDR).
open source escape hatches
- FraudLabs / open rules engines (Drools) Apache-2.0
- Feedzai alternatives — River BSD-3
- MaxMind minFraud open clients Apache-2.0
