Oso
Visibility and controls to secure agents. Agents are here. Oso makes them safe.

Oso is an authorization and agent security platform that helps organizations implement fine-grained access control for both traditional applications and AI agents. It provides automated least-privilege enforcement, visibility into agent permissions, and compliance tooling to prevent AI agents from inheriting excessive human access rights. Engineering teams use Oso to implement RBAC, ReBAC, and ABAC without building custom authorization logic from scratch.
Oso integrates into application stacks to enforce fine-grained authorization policies using its Polar rule language, automatically applying least-privilege access controls to both user and agent interactions.
