Datadog AI Guard is a defense-in-depth product designed to **inspect**, **block**, and **govern** AI behavior in real time. AI Guard is built to plug in directly with existing Datadog tracing and observability workflows to secure agentic AI systems in production. It sits **inline with your AI app/agent** and layers on top of existing prompt templates, guardrails, and policy checks, to **secure your LLM workflows in the critical path**.

AI Guard protects against prompt injection, jailbreaking, and sensitive data exfiltration attacks with Prompt Protection, Tool Protection, and Sensitive Data Protection. Together, these capabilities protect against the [agentic lethal trifecta](https://simonwillison.net/2025/Jun/16/the-lethal-trifecta/):

- Privileged system access
- Exposure to untrusted data
- Outbound communication

AI Guard also detects sensitive data such as personally identifiable information (PII) and secrets in LLM inputs and outputs. These protections work for any target AI model, including OpenAI, Anthropic, Bedrock, VertexAI, and Azure. To see your AI agents and services mapped out, including how they interact with each other and which ones AI Guard is protecting, go to the [Discover](https://app.datadoghq.com/security/ai-guard/discover) page.

To quickly evaluate a conversation without any code or setup, use the [AI Guard Playground](https://docs.datadoghq.com/security/ai_guard/onboarding.md#playground) to submit user input, assistant output, and tool calls, and see the evaluation result in real time.

For information on how to set up AI Guard, see [Get Started with AI Guard](https://docs.datadoghq.com/security/ai_guard/onboarding.md).
