The BYOK Threat Model
BYOK = your organization supplies its own provider API keys instead of using a shared vendor key. It gives you control — and a new attack surface.
What you are defending against:
1.Key exfiltration — a leaked key bills you and exposes your traffic.
2.Prompt-side data leaks — PII or secrets sent to a third-party model.
3.Confused-deputy — a low-trust workflow using a high-trust key.
4.Provider compromise — assume the provider *could* be breached; minimize blast radius.
Principle: the model provider is untrusted infrastructure. Treat every outbound call like it crosses a trust boundary, because it does.
