# Introduction

> The control plane for managing AI agents across your organization

# Introduction

Spellguard is the control plane for managing AI agents across your organization — multi-vendor, multi-department, unified governance. Get visibility into every agent, enforce policies consistently, and maintain audit trails across your entire agentic infrastructure.

For secure agent-to-agent communication, Spellguard provides two core protocols that you can use independently: **cTLS** and **AMP**.

    **Cloud Transport Layer Security** implements bidirectional attestation and secure channel establishment for agents regardless of the hosting provider.

  <Card title="AMP" icon="scroll" href="/specifications/amp/overview">
    **Admissible Messaging Policy** provides tamper-evident audit logs and secure message archiving between two parties without requiring trust of either side's account.
