Oso Security provides a platform that helps software developers add and manage authorization features in their applications. It offers authorization tooling that developers can integrate to control who can access what, handling user roles and permissions, as either Oso Cloud (cloud) or Oso On-Premises (self-hosted) with subscription pricing and optional consulting. Developers embed Oso’s libraries into their apps so the platform enforces access rules and scales with their products. Its goal is to make accurate, scalable authorization easy for software teams, reducing security risk and speeding up development.

Leaflink purchased Oso through AWS Marketplace, simplifying procurement and integration. "With Oso, we were able to adopt a powerful, flexible authorization system that fits our legacy and horizon architecture and lets our team move faster," said Steffne "Stevie" Palmateer, CTO of Leaflink. "Buying through AWS Marketplace made the process seamless and supported our enterprise plan. Partnering with Oso is a win for our developers and for our customers." If you're an AWS customer looking to solve authorization, you can book a complimentary authorization review with one of its engineers. Oso GTM.
