What is Oso?

Editorial review
Oso provides a unified authorization layer designed to manage access for AI agents, applications, and human users. It addresses the complex challenge of authorization, especially with the emergence of agentic AI, by enforcing least privilege principles. The platform monitors agent actions, detects anomalous or risky behavior, and enables dynamic privilege adjustments, alerting, and quarantining to prevent over-permissioning and ensure security. Oso is built for engineering teams who need to implement consistent and robust authorization logic across their platforms without building it from scratch. It offers visibility into agent activities, controls to set boundaries, and immutable audit trails for compliance. The solution supports various authorization models like RBAC, ReBAC, and ABAC, and is engineered with strict security and privacy controls to serve as a reliable foundation for modern application architectures and permission-aware AI workloads.

Oso FAQ

How does Oso specifically secure AI agents?

Oso secures AI agents by providing visibility into their actions, enforcing least privilege for every tool call, and setting boundaries to prevent unauthorized data access or infrastructure changes. It also simulates agent behavior in staging and detects anomalous activities in production, quarantining agents and rolling back changes if necessary.

What types of authorization models does Oso support for applications?

Oso supports a range of authorization models including Role-Based Access Control (RBAC), Relationship-Based Access Control (ReBAC), Attribute-Based Access Control (ABAC), and any custom authorization logic required by an application.

What is included in the Developer free plan?

The Developer free plan includes access to Oso Cloud with a 99.5% SLA, community Slack support, and a rate limit of 100,000 events per month.

How does Oso define and count Monthly Active Users (MAU) for billing?

Oso counts MAUs based on unique user identifiers that are the subject of authorization queries within a given month. If User{"Alice"} performs multiple actions or queries a list of 1,000 profiles, it still counts as one MAU.

Can Oso be deployed on-premise or in a hybrid cloud environment?

Yes, the Enterprise plan offers flexible deployment options including cloud, hybrid, or on-premise installations, along with custom SLAs and support.
