Oso

Founded 2018

Manage authorization and security policies for applications and AI agents

Pricing model

Free Tier, Paid

You can use Oso to manage permissions and secure AI agents across your organization. It lets you discover unsanctioned agents running on laptops, terminals, or browsers, and monitor live AI traffic including prompts, tool calls, and outputs. You can build fine-grained access rules using role-based or attribute-based controls with the Polar policy language. Oso tracks rule violations, detects sensitive data leakage like API keys or personally identifiable information, and maintains complete compliance logs to help engineering teams control agentic behavior in production.
