Easily add resource-level permissions to any SaaS. Multi-tenant applications need more than roles in isolated environments. They need fine-grained permissions.

Go beyond roles

Justified access, not just access. Marry user information from your identity providers and directories with dynamic context data from your application, to ensure that only the right users can access the right resources.

Identity & context-aware access

Authorize in a millisecond, based on fresh data. Enjoy the blazing fast authorization of a local microservice, with the scalability of a distributed system.
