Aserto is a cloud-native authorization platform that allows developers to get out of the business of rolling out custom access control solutions, and instead focus on their core user experience.


Aserto has two major components:

  • Authorizer: where authorization decisions are made
  • Control Plane: manages all the artifacts that Aserto uses to make authorization decisions


The Authorizer is an open source authorization engine which uses the Open Policy Agent (OPA) to compute a decision based on a policy, user context, and data. It is most commonly deployed close to your application, to offer the lowest latency and the highest level of availability to your application.

Control Plane#

The Aserto Control Plane manages the lifecycle of policies, user context, and data that are used by the authorizer. The control plane makes it easy to manage these artifacts centrally, and takes care of the details of synchronizing them to the Authorizer instance(s) deployed at the edge.

The control plane also aggregates all of the outputs from the Authorizers, including decision logs, to give an administrator a centralized, single-system view of a complex distributed system.
