Arcjet
What is Arcjet?
Arcjet is a runtime security platform for developers building AI agents and applications. SDKs and agent hooks check proposed actions against configurable policies before execution. The platform combines enforcement with observation and audit records for reviewing agent behavior. Teams can test policies in dry-run mode and update rules through a central console.
How to use Arcjet?
- Create an Arcjet account and integrate the appropriate SDK or supported coding-agent hooks.
- Define policies for the actions, data, destinations, and request limits your application needs.
- Inspect decisions in dry-run mode, adjust the rules, and enable live enforcement when ready.
Arcjet's Core Features
Action Guards: Check typed action inputs against authorization rules before a tool runs.
Prompt-Injection Detection: Evaluate text for prompt-injection signals within guarded workflows.
Sensitive-Data Protection: Apply configured detection and redaction policies to sensitive values.
Destination Checks: Evaluate outbound destinations against policy and threat information.
Usage Limits: Rate-limit requests by dimensions such as user, tool, or tenant.
Dry-Run Mode: Observe policy decisions before enabling blocking behavior.
Remote Policy Updates: Publish policy changes without redeploying the application.
Decision Auditing: Inspect policy versions, inputs, and decisions associated with agent activity.
