our call
Start with Sift — 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.

Sift
An AI coding agent can write a custom rule engine, device fingerprinting intake, and XGBoost fraud scoring API in a couple of weeks. However, you cannot replicate Sift's global data network, which uses cross-merchant behavioral signals across 34,000+ sites to stop fraud on arrival.
you can rebuild
- Client-side JS snippet integration for basic device signal capture
- Custom rule builder for block/allow lists (e.g., country code matching, velocity limits)
- Real-time scoring API endpoint returning risk numbers (0-100)
- Manual investigation review queue console for fraud analysts
- Shopify and Magento webhook trigger integrations
what you lose
- Access to Sift's global consortium data tracking over 1 billion unique digital personas
- Pre-trained cross-merchant Account Takeover (ATO) and identity theft detection models
- Sift ActivityIQ generative AI pattern detection across global network events
- Out-of-the-box integrations with major enterprise processors (Adyen, Stripe, PayPal) and platforms
- Automated continuous machine learning retraining on global chargeback data
real moats
- Global Consortium Network: Shared signal intelligence across thousands of global enterprises processing 70B+ events monthly.
- Petabyte-Scale Behavioral Graph: Historical link analysis linking IPs, device hashes, credit card bins, and shipping addresses across decades.
- Zero-Day Fraud Vector Detection: Ability to detect novel botnet and account takeover patterns before individual merchants experience them.
