# Pay App Guard

*/Startups/Pay_App_Guard*

## Startup Overview

This security layer intercepts malicious transaction payloads directly at the API gateway. By parsing incoming requests before they reach internal microservices, it blocks fraudulent transfers, injection attacks, and application logic exploits. It operates entirely inline, dropping bad traffic without requiring post-event reconciliation.

Engineering teams building high-volume digital payment platforms face a constant barrage of payload manipulation. Because modern financial transactions process instantaneously, waiting for asynchronous risk scoring or batch review allows theft to clear. This deployment eliminates the gap between request and execution, neutralizing threats before the core application processes any financial data.

Unlike legacy web application firewalls or basic in-house rate limiting that only evaluate headers and IP reputation, this engine deeply inspects the actual transaction payload. Compared to external fraud APIs like Sift, it functions as a developer-native, synchronous gateway extension. The architecture is explicitly optimized for zero-latency inspection, ensuring legitimate payments clear without delay while malicious inputs are destroyed at the edge.

## Startup Offer

**Proof**:
- Fintech startups aiming to reduce false positive fraud blocks without impacting checkout latency.
- High-volume e-commerce platforms targeting zero-latency payload inspection at peak holiday volumes.
- Payment processors seeking to replace legacy WAFs with API-native transaction interception.
**Tiers**:
- Name: Starter Volume · Price: ~$0.003–$0.005 per payload · Inclusions: Core transaction payload inspection intended for up to 250,000 monthly API calls with standard fail-open gateway routing.
- Name: Scale Volume · Price: ~$0.001–$0.002 per payload · Inclusions: High-volume processing for up to 5 million monthly API calls, custom rule thresholds, and intended SIEM log streaming.
- Name: Dedicated Gateway · Price: enterprise: ~$30k–$60k/yr · Inclusions: Flat-rate enterprise volume, dedicated isolated clusters, sub-millisecond latency guarantees, and custom deployment support.
**Guarantee**: Guarantees sub-millisecond latency added to intercepted API calls; if payload inspection causes a measurable timeout exceeding the SLA, the month's service fee is fully refunded.
**Business Function**: ProvideService
**Objection Handlers**:
- Adding an inspection layer at the gateway will increase our API latency: The engine is optimized for sub-millisecond payload processing designed explicitly not to bottleneck transaction flows.
- We already use a standard WAF for our web traffic: Legacy WAFs look at headers and basic injection patterns; this parses and scores the actual JSON transaction payload for malicious business logic.
- Integration will require modifying our core payment processing code: It is intended to run directly as a plugin at your existing API gateway without requiring changes to downstream application services.
- What if the service goes down and blocks all legitimate payments: The gateway integration is designed to fail-open by default, ensuring transactions continue to process even if the inspection engine is unreachable.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A 14-day shadow mode deployment at the API gateway to prove the engine successfully parses JSON transaction payloads with sub-millisecond latency before moving to active blocking.
- A 30-day active inspection pilot on a secondary payment routing endpoint to demonstrate the fail-open design maintains transaction continuity during controlled service disruptions.
**Target Metrics**:
- Target: <1 millisecond processing latency added per intercepted transaction payload
- Aim: 0% increase in checkout timeout errors during high-volume API surges
- Target: 100% fail-open routing execution during simulated inspection engine downtimes
- Aim: >90% reduction in false-positive blocks compared to legacy WAF header inspection rules
**Target Case Studies**:
- A mid-market fintech processor led by a CTO replaces a legacy WAF with API-native payload parsing to intercept malicious business logic without increasing transaction timeouts.
- A high-volume e-commerce platform directed by a VP of Engineering processes peak checkout API calls while isolating JSON-level anomalies, validating the sub-millisecond latency guarantee.
- A Series B payment gateway guided by a Head of Security implements fail-open transaction interception, ensuring zero dropped legitimate payments during simulated security engine outages.
**Testimonial Targets**:
- CTO of a payment processor expressing relief that the gateway plugin intercepted malicious JSON payloads without requiring any modifications to the core payment application code.
- VP of Engineering sharing satisfaction that the sub-millisecond latency guarantee holds up perfectly without bottlenecking transaction flows during peak traffic spikes.
- Head of Information Security highlighting confidence in the fail-open architecture, proving that the security layer never accidentally drops legitimate checkout traffic.
