our call
Start with SEON — highest vibe code, weakest moat.
SEON
A custom rules engine and transaction dashboard take days to code, but SEON's core value lies in its proprietary OSINT lookups and cross-merchant fraud signals. Rebuilding the software UI is simple, but aggregating social data and phone carrier intelligence across millions of profiles independently is economically unviable.
you can rebuild
- Custom drag-and-drop risk scoring rules engine
- Transaction review dashboard with manual approve/reject flags
- Shopify checkout webhook handler for order hold/cancel
- Basic IP geolocation and proxy detection logic
- Custom risk score calculator and threshold triggers
what you lose
- Real-time social profile footprinting across 35+ services
- Cross-merchant global fraud reputation network
- Telco carrier lookup for disposable phone numbers
- Evasion-resistant device fingerprinting JS agent maintenance
- Zero-maintenance ML models trained on billions of transactions
real moats
- Cross-merchant fraud intelligence graph
- Proprietary OSINT scraping and reverse lookup infrastructure
- Direct carrier and identity data provider integrations

- Holehe GPL-3.0
- KIE Drools Apache-2.0
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.
