LLM PRIVACY GATEWAY

Put a privacy boundary between your app and your model provider.

NullTrace is middleware for LLM traffic. It inspects supported PII, secrets, and prompt-injection signals and can forward sanitized OpenAI-compatible chat traffic with your own provider credential.

Centralize the policy without taking over the stack.

When multiple services call an LLM, each service can otherwise implement different sanitization rules. A gateway turns common checks into reusable infrastructure.

NullTrace does not host models, select providers, or pay provider invoices. Provider choice stays with the application.

BYOK

X-NullTrace-Key: <TENANT_KEY>
Authorization: Bearer <PROVIDER_KEY>

The keys serve different purposes: tenant authentication at NullTrace and upstream provider authorization.
