Authorization for agent tool calls
Sensitive data and PII redaction
Bot and abuse blocking
Security building blocks called inside your app's code
Policy enforcement and audit evidence for agent actions
Use Cases

Why do startups need this tool?
Startups building AI agents can use Arcjet to add runtime security directly in code, protecting against prompt injection, abuse, and data exposure without leaving their development workflow.
