our call
Start with FraudLabs Pro — highest vibe code, weakest moat.
FraudLabs Pro
Coding a custom rule evaluation engine (e.g., flag order if billing country differs from IP country) is trivial. However, FraudLabs Pro relies on global blacklists, IP risk intelligence, and cross-merchant chargeback data that you cannot replicate in a standalone application.
you can rebuild
- Custom rule builder engine (e.g. IF order > $500 AND shipping != billing THEN flag)
- Manual order review status dashboard and approval queues
- Velocity checking per customer email or IP address
- Disposable email domain blacklisting using static open-source lists
- Automated order hold status updates via e-commerce platform webhooks
what you lose
- Access to a global cross-merchant blacklist of malicious buyers and emails
- Proprietary real-time IP reputation, proxy, VPN, and TOR exit node detection data
- Cross-site device fingerprinting telemetry
- Phone number and carrier risk scoring lookups
- Historical global chargeback statistics associated with individual buyer attributes
real moats
- Proprietary global dataset of reported fraud cases across thousands of online stores
- Network effects: every merchant reporting a chargeback strengthens protection for all other users
- Deep integration with commercial IP intelligence databases (such as IP2Location)
open source escape hatches
- json-rules-engine MIT
- Apache Unomi Apache-2.0
- Rspamd 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).
