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
Shield
Shield relies on global device telemetry pooled across thousands of applications to spot bad actors. While an AI agent can generate a local browser fingerprinting script in minutes, an isolated application cannot replicate Shield's global fraud graph, emulator detection updates, or proxy intelligence.
you can rebuild
- Basic browser attribute collection script
- Rule-based threshold scoring (e.g., flag orders over $500)
- IP geolocation lookup integration
- Manual fraud review queues and admin UI
- Webhook notifications for flagged orders
what you lose
- Global cross-merchant malicious device registry
- Advanced Android and iOS emulator detection
- Real-time behavioral biometrics analysis (typing/tap cadence)
- Continuous arms-race counter-measures against browser spoofing extensions
- Low false-positive ML models trained on billions of sessions
real moats
- Global cross-merchant dataset of device IDs and associated fraud events
- Dedicated reverse-engineering research team tracking native OS exploits
- Proprietary ML scoring infrastructure operating sub-50ms globally
open source escape hatches
- FingerprintJS BBSL
- MaxMind GeoIP2 Apache-2.0
- Apache SpamAssassin Apache-2.0
Questions people ask
Which is easier to rebuild with AI, FraudNet or Shield?
FraudNet. It scores 5/10 on vibe code with a moat of 7/10, so an AI-assisted MVP takes about 1 week and a full replacement about Never (Requires cross-merchant global transaction network and device intelligence).
Which one costs less, FraudNet or Shield?
FraudNet at $899/mo/mo for a typical mid-market store. The gap between the two is about $13,212/mo a year.
