One Gateway for Every Model

We watched brilliant engineers at primes paste CUI into consumer chatbots because the approved tooling was a 2019 wiki.

Route

OpenAI-compatible API in front of GovCloud Bedrock, Azure Government, and self-hosted models. Swap the base URL and ship.

Redact

CUI and ITAR-sensitive strings are scrubbed at the boundary before anything leaves your enclave. Powered by our in-house classifier.

Prove

Every prompt and completion is logged with cost attribution and exportable on demand. Assessors get the report they ask for.

Founders

We left our return offers to build for the people defending the free world.
