our call
Start with Trustfull — highest vibe code, weakest moat.
Accertify
Building a custom rules engine with an AI assistant takes a couple of weeks, but Accertify's moat is its vast cross-merchant transaction database and hardware fingerprint network. An isolated self-hosted application has no access to global stolen card data or collective threat intelligence. You can easily build the admin workflow, but your fraud engine will be blind to external threat actors.
you can rebuild
- Manual order review queue and analyst decision workflow UI
- Custom merchant-defined risk scoring rules engine
- Basic velocity checking and IP geolocation distance verification
- Webhook triggers to hold or release risky orders in ecommerce backends
- Basic analytics dashboards tracking approved versus flagged transactions
what you lose
- Cross-merchant global transaction and stolen card threat network
- Automated chargeback representment and dispute resolution pipelines
- Hardware-level mobile and web browser device fingerprinting SDKs
- Dedicated 24/7 enterprise threat analyst team and performance SLAs
- Pre-built processor and card brand network dispute connections
real moats
- Proprietary cross-merchant fraud signals accumulated across billions of checkout events
- Direct integrations with issuing banks and chargeback networks
- Contractual performance SLAs and financial chargeback protection options

Trustfull
AI can write a full-featured risk rule engine and signal aggregation service in a afternoon. However, you cannot easily replicate Trustfull's underlying access to direct mobile carrier networks, HLR lookups, and global breach databases without paying high third-party data fees.
you can rebuild
- Custom risk scoring rule builder and threshold evaluation engine.
- Basic IP risk lookup (VPN/Tor/Proxy detection via public databases).
- Email syntactical analysis, disposable domain checks, and MX record verification.
- Redis-based velocity tracking for identity fields (e.g., requests per phone number per hour).
- Audit logging and structured API response formatting.
what you lose
- Direct access to real-time mobile network operator (HLR/SS7) data without setting up separate vendor contracts.
- Cross-merchant global reputation data on fraudulent phone numbers and email addresses.
- Unified billing and SLA management for multi-signal data sources.
- Pre-built compliance workflows for European privacy standards (GDPR) regarding identity lookups.
real moats
- Proprietary integrations and wholesale volume rates with international HLR/telecom data aggregators.
- Aggregated historical data on phone/email reputation built across millions of evaluation requests.
- Low-latency global API infrastructure serving unified risk responses under 100ms.
