Permit.io is a full-stack-authorization solution - covering all the layers required for building access-control for products and services - Infrastructure (e.g. Policy-engines, SDKS, APIs), Backoffice (the controls the team behind the product needs), and end-user interfaces (e.g. user management, audit logs, api-keys, and more).
A key part of Permit.io’s infrastructure is the open-source combo of OPA / AWS Cedar and OPAL.
OPA (Open-Policy-Agent) and AWS Cedar are policy-based decision engines, and OPAL (Open-Policy-Administration-Layer) is a realtime solution to keep policy agents updated with the policies and data they need, in an event-driven distributed fashion.
When you use Permit.io’s authorization microservices you get OPA+OPAL as a built-in default.
