Stop your AI agents from leaking your secrets.

How is this different from built-in sandboxing?
How is this different from built-in sandboxing?
Tools like Claude Code and Cursor offer basic network sandboxing - IP allowlists that block or allow entire domains. That's a lock on the door. Rashomon reads every package that goes through the door. It inspects payload contents for secrets, detects anomalous patterns, understands which AI agent is making the request, and gives you approve/deny controls with full explanations. Sandboxing controls where traffic goes. Rashomon understands what's inside it.
