our call
Start with Subuno — 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.

Subuno
Subuno's underlying tech is an IF/THEN rules engine connected to third-party identity/risk lookup services. Rebuilding the UI and rule execution in Node.js is trivial, but maintaining contracts, schema mappings, and API keys for a dozen external fraud vendors is not worth the overhead for most merchants.
you can rebuild
- Custom IF/THEN rule engine for flagging high-risk orders
- Manual order review queue with approve/reject actions
- Email alerts and webhook triggers for flagged transactions
- Basic IP geolocation and address verification (AVS) checks
- Custom merchant-defined whitelists and blacklists
what you lose
- Pre-integrated access to 15+ external fraud data providers
- Unified billing and unified payload normalization across third-party identity APIs
- Cross-merchant shared bad-actor detection network
- Zero-maintenance e-commerce store platform plugins
- Turnkey automated order status updating in connected store platforms
real moats
- Aggregated integration maintenance across a broad mesh of specialized risk APIs
- Cross-merchant shared blacklists and fraud signal history
- Low subscription fee relative to managing multi-vendor API overhead directly
