AI agent security and control platform
Oso helps companies run AI agents in production with confidence by providing monitoring, access controls, and automated least privilege. It discovers all agents running across laptops, browsers, and terminals, monitors their prompts and tool calls, detects rule violations and anomalies like PII leakage, and enforces custom policies. The platform offers complete logs for compliance and incident investigation, and includes a registry of real-world agent failures and exploits.
