Overview

The Styra DAS Emissary-ingress system type helps you manage the client API requests permitted within your OPA-integrated Emissary-ingress Gateway. For example, permit API requests only to predefined backend APIs to minimize the risk of data exfiltration or implement microservice API authorization.

For more information on how OPA can be integrated with Emissary-ingress for API authorization and enforce security policies over client API requests received by Emissary-ingress, see the Emissary-ingress tutorial.
