What is Control Zero?

Control Zero is a Smart SDK that adds governance, security, and observability to your LLM applications. It runs inside your app — not as a separate proxy — giving you enterprise-grade security without the latency or complexity.

Core Capabilities

Everything you need to secure and govern your AI applications

Secret Management

Inject API keys at runtime, never hardcode. Secrets are fetched on-demand, encrypted, and wiped on session end.

Policy Engine

Granular access control with conditions. Time-based, role-based, and IP-based rules with default-deny model.

Audit Logging

Every action tracked, queryable, and exportable. ClickHouse-powered for blazing-fast queries.

Environment Management

Complete Dev/Staging/Prod isolation. Different secrets and policies per environment.

Architecture That Makes Sense

Unlike traditional proxies that route all your traffic through a third party, Control Zero runs in-process. Your data goes directly to LLM providers.

✗ Traditional Proxy Architecture

Your App → Proxy Server → LLM Provider

  • •All traffic routed through third party
  • •Added latency on every request
  • •Single point of failure
  • •Data passes through external servers

✓ Control Zero Smart SDK

Your App (with SDK) → LLM Provider

  • •Direct connection to providers
  • •Zero latency for valid requests
  • •No external dependency
  • •Your data never touches our servers

Two Integration Patterns

Choose the pattern that fits your architecture

Service Gateway

Centralized secrets for backend agents. Perfect for microservices and batch processing.

python
# Service Gateway Pattern
cz = ControlZero(
    api_key="cz_...",
    mode="service",
    environment="production"
)
# Secrets injected from central vault
llm = cz.wrap(ChatOpenAI())

User Pass-through

Per-user credentials for user-facing apps. Each user brings their own API keys.

python
# User Pass-through Pattern
cz = ControlZero(
    api_key="cz_...",
    mode="passthrough",
    user_id=current_user.id
)
# User's own API key injected
llm = cz.wrap(ChatOpenAI())
