our call
Start with Signifyd — highest vibe code, weakest moat.
Forter
AI can build an e-commerce device fingerprinting script, rule engine, and risk-scoring API in a few weeks. However, enterprise merchants pay Forter $120k+/year primarily for chargeback indemnification and a trillion-dollar network graph, neither of which can be replaced by software alone.
you can rebuild
- Real-time browser and device fingerprinting JavaScript SDK
- IP reputation scoring, proxy/VPN detection, and datacenter IP identification
- Configurable risk-scoring engines and custom rule builders
- Address Verification System (AVS) and Card Verification Value (CVV) mismatch logic
- Order status API hooks for platform integrations (Shopify, Magento, WooCommerce)
what you lose
- 100% Chargeback Financial Guarantee: Forter pays out of pocket for any approved order that results in a fraud dispute.
- The Global Identity Network: Instant detection of professional fraud syndicates operating across multiple distinct enterprise storefronts.
- Issuer-side 3DS Optimization: Automated conversion boosts through direct data pipelines into issuing bank authorization engines.
- Zero manual review overhead: Entirely automated decisioning backed by legal indemnity.
- PCI-DSS Level 1 managed infrastructure for sensitive payload inspection.
real moats
- Financial guarantee balance sheet: Forter acts as an insurance underwriter for chargebacks; code cannot replicate financial risk absorption.
- Proprietary cross-merchant global identity graph analyzing hundreds of billions of dollars in transaction data.
- Direct partnerships with major card networks (Visa, Mastercard) and issuing banks for 3DS liability shift optimization.

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

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).
