# The risky way 😬
import openai
client = openai.OpenAI(
api_key="sk-proj-abc123..." # Hardcoded secret!
)
response = client.chat.completions.create(
model="gpt-4",
messages=[{"role": "user", "content": prompt}]

# No logging, no policies, no audit trail...

# The Control Zero way
from control_zero import ControlZero
cz = ControlZero(api_key="cz_...")
# Secrets injected, policies enforced, calls logged
client = cz.get_client("openai")
response = client.chat.completions.create(
model="gpt-4",
messages=[{"role": "user", "content": prompt}]
)
# That's it. You're governed.

What is Control Zero?

A lightweight SDK that wraps your LLM calls to provide enterprise-grade governance without the enterprise complexity.

Secret Management

Secrets injected at runtime. Never stored in code, never exposed in logs.

AES-256-GCM encrypted

Policy Engine

Granular access control with conditions. Block, allow, or rate-limit by user, model, or context.

Evaluated locally

Audit Logging

Every LLM call logged with full context. Query, analyze, and export your AI usage.

ClickHouse powered

Cost Tracking

Real-time visibility into token usage and costs across all providers and models.

Per-user attribution

How is Control Zero different?

Zero Latency

Policies evaluated locally in your app. No network hop for valid requests.

No Proxy

Your traffic goes directly to LLM providers. We never see your prompts or responses.

No Lock-in

Export your data anytime. Switch providers freely. Your data is always yours.

Traditional Proxy Approach

All traffic routed through third party • Single point of failure • Data exposure risk

Control Zero SDK Approach

LLM

Zero added latency • No proxy • Your data stays yours • Policies run in-process

How it works

The SDK runs in your app — not as a separate proxy. Valid requests have zero added latency.
