Enforce policy.
Stay compliant.
Govern every
agent action.
Prove it to
anyone who asks.

Aurek sits between your agent framework and every action your agents take. Every tool call, resource access, and inter-agent message is evaluated against policy before it executes. Developers ship it in an afternoon. Compliance teams get the audit trail they need before anyone asks for it.
