# Tonion > Tonion is the control plane for AI agents - an enterprise-grade governance, observability, and compliance platform that lets teams deploy autonomous agents safely and at scale. Tonion sits as a policy layer between your agent framework and your production environment. It intercepts every agent action in real time, evaluates it against configurable policy rules, and either allows, blocks, or routes it for human review - without requiring changes to your agent code. ## What Tonion Does - **Agent governance**: Define and enforce policies that control what actions AI agents are permitted to take, in what context, and under what conditions. - **Agent observability**: Full session-level tracing of every agent decision, tool call, and output. Understand what your agents are doing and why. - **Human-in-the-loop (HITL)**: Route high-stakes agent actions to human reviewers via Slack, Email, or Microsoft Teams for approval or denial before execution. Approved actions proceed automatically. - **Immutable audit logs**: Tamper-evident, append-only logs for every agent run with full context, rationale, and reviewer attribution. - **Agent cost governance**: Track, cap, and allocate LLM token spend and compute costs across agent fleets in real time. - **Compliance exports**: Automatically generate evidence packages for regulatory frameworks including the EU AI Act, SOC 2, and GDPR. - **Multi-framework support**: Native SDK integration with LangGraph, LlamaIndex, CrewAI, AutoGen, Google ADK, and OpenAI Agents SDK. - **Enterprise security**: SSO, RBAC, VPC deployment, SLA guarantees, and dedicated support. ## Key Concepts - **Policy engine**: YAML-based policy definitions that are versioned, testable, and deployable like code. Policies can block, allow, modify, or escalate agent actions. - **Agent registry**: A catalog of all agents running in your environment, their capabilities, their policy assignments, and their runtime status. - **Control plane**: Tonion acts as the central nervous system for your agent infrastructure - a single integration point for governance, observability, and compliance across all agent frameworks. - **Intercept layer**: A lightweight SDK wrapper that evaluates every tool call and action against policies before execution, with sub-100ms latency. ## Who Uses Tonion - **Platform engineers** building safe agent infrastructure without modifying agent code - **Security and compliance teams** meeting regulatory requirements for autonomous AI systems - **Product and operations teams** shipping agents to end users with confidence ## Pages - [Home](https://tonion.ai): Product overview, features, integrations, and demo request form - [About](https://tonion.ai/about): Company background and founding story ## Contact - Demo requests: [https://tonion.ai/#book-demo](https://tonion.ai/#book-demo) - Email: support@tonion.ai
