Arcjet - Security for AI agent operations

Arcjet provides runtime security solutions specifically designed for AI agents. It focuses on preventing unauthorized actions, blocking prompt injections, and safeguarding sensitive information. The platform offers various protective measures, ensuring that AI applications operate securely and efficiently. With features like bot protection, rate limiting, and data loss prevention, Arcjet aims to enhance the security of AI workflows.

1. Prompt Injection Detection

   Arcjet employs advanced detection mechanisms to identify and block hostile instructions in user inputs and tool outputs before they reach the AI model.

2. Sensitive Information Protection

   The platform strips sensitive data, such as personal identifiable information (PII), before it can be processed or logged, ensuring data privacy.

3. Abuse Protection

   Arcjet includes features to protect web applications from abuse, including bot detection and rate limiting to manage traffic effectively.

4. Budget Control

   Users can set token and spend budgets to prevent runaway processes from exhausting resources, ensuring cost-effective operation.

5. Integration with Various Frameworks

   Arcjet supports multiple SDKs and frameworks, making it easy to integrate security measures into existing applications.

6. Real-Time Policy Management

   Security policies can be managed remotely, allowing for immediate updates without requiring code deployments.

7. Audit and Evidence Collection

   Every decision made by the system is logged with context, providing a comprehensive audit trail for security reviews.

1. Install the Arcjet SDK and create a client with your specific rules.
2. Integrate Arcjet into your application code where actions are taken, using the protect() or guard() functions.
3. Test the integration in dry run mode to observe decisions without blocking actions.
4. Regularly review and update security policies to adapt to new threats.

How do I add runtime security to AI agents in production?

Install the Arcjet SDK, create a client with your rules, and call it inside the code path that takes the action.

How do I stop AI agents from taking unsafe or unauthorized actions?

Implement checks at the action boundary, scoping each tool call by identity, role, and input, and refuse the call before execution.

How is this different from an AI control plane or an MCP gateway?

Arcjet is integrated directly into the application code, allowing decisions to be made with full context, unlike external control planes that operate separately.

How do I prevent prompt injection in production LLM applications?

Use Arcjet's detection model to catch hostile instructions before they reach the AI model, allowing you to decide on the appropriate action.

How do I enforce token and spend budgets on AI agents?

Utilize a token bucket system keyed to user and organization characteristics, passing the estimated cost of the call as the requested amount.
