PasskeyBridge: Identity Threat Engine – API-driven Identity Threat Response with Post-Quantum Security

Summary: PasskeyBridge is an Identity Threat Response as a Service (ITRaaS) platform that ingests carrier-level threat signals like SIM swaps and port-outs via a single API, triggering deterministic JSON playbooks and secure callbacks. It employs zero-PII storage, hybrid post-quantum cryptography, and AI-based behavioral analysis to enhance identity threat detection and response in high-security environments.

What it does

PasskeyBridge processes threat signals through a multi-tenant API, matching them against JSON-defined response playbooks that execute sequential actions such as webhooks and alerts. It uses HMAC-SHA256 signed callbacks, stores no raw PII by hashing data, and integrates a self-hosted verifiable credentials engine for credential revocation.

Who it's for

The platform targets organizations needing to automate and secure responses to carrier-level identity threats and behavioral anomalies without managing multiple fraud APIs or custom logic.

Why it matters

It addresses the complexity of reacting to identity threats by consolidating detection and response into a single secure API with advanced cryptographic protections against future quantum attacks.
