Authorisation platform built on the Polar declarative policy language, delivered as the hosted Oso Cloud service with open-source Polar client libraries.
Why it matters for NETEVO
Oso models application authorisation in the Polar declarative language and answers questions such as whether a given actor may take a given action on a given resource, and which resources an actor may access. The current product is the hosted Oso Cloud service; the Polar language and the Oso client libraries are open source under Apache-2.0. Among policy engines, Oso is the commercial managed-service alternative to the open-source engines Cedar and OPA.
Oso Cloud is commercial with proprietary terms; only the Polar language and the client libraries are Apache-2.0. Any evaluation of Oso therefore needs to distinguish the hosted platform from the open-source language. For an organisation weighing policy-engine adoption, the choice is between self-hosting an open-source engine and procuring a managed service — both legitimate, with the familiar infrastructure trade-off between operational overhead and vendor concentration.
The maintained path is Oso Cloud. Current documentation is published at osohq.com/docs.
