One engine for all your authorization needs
Define powerful access logic, enforce it consistently, and scale it to any use case
Complex authz features made simple
Oso makes it easy to implement any permissions model, and supports advanced functionality like fine-grained access controls and user-defined roles.
No more brittle authz code
Centralize your authorization data, policies, and enforcement to improve maintainability, increase feature velocity, and enhance your security posture.
Connect user data to AI systems, safely
Propagate and enforce user permissions across RAG pipelines and agentic systems to ensure data leaks are a thing of the past.

“I'm sold on this way ahead for the known future. Oso has nailed the abstractions.That’s the hardest part to get right, and the hardest part to change later.”
“Oso is a compelling fit because of their singular focus on authz, plus the flexibility of their Polar rule definitions. Within twenty minutes we’d managed to define a custom Polar definition to handle our current use case."
“We needed to manage authorization across all of our new microservices. The answer was the Oso authorization framework."
“Oso is A+. As we moved upmarket, being able to implement authz consistently and accurately helped us move faster and resolved a never-ending source of bugs.”
“We reviewed multiple solutions – Oso came out on top for its devex, scalable and consistent performance, and the flexibility to match all our needs.”
“It used to take us months to add new roles. With Oso we cut that time 10x. The Oso team has also been very helpful, making our migration super smooth.”
“Oso has been huge for us. It has the most intuitive model. It’s the most mature, and has the best tooling and docs. And the support has been unreal.”
“Oso was the fastest path to building roles and has been incredible – easy to wrap our heads around, great docs, and makes life much simpler.”
"We were able to build and deploy a sample app with Oso in an afternoon versus several days for the others. It was significantly faster to get started out of the box."
Let's see some code.
