Overview
Multinex Shield is the ultimate safeguard for enterprise intellectual property. It operates as an impenetrable, high-throughput bidirectional firewall sitting squarely between your internal networks and external LLMs. By weaponizing an ultra-low-latency Aho-Corasick algorithm, Shield intercepts, parses, and redacts restricted PII and proprietary logic in milliseconds—guaranteeing your corporate data never leaks into public training datasets.

- Ingress: A client sends an OpenAI-formatted request to the local Deno Gateway.
- Classification: The gateway passes the payload memory to the Rust-based classifier, scanning for millions of prohibited patterns in
O(n)time complexity. - Mutation/Rejection: Hard-block rules trigger a 403. Redaction rules replace offending strings with
<REDACTED>. - Egress: The sanitized payload is securely forwarded to the external LLM provider.
