Policy as Code to Control Service Mesh
Styra DAS lets you incorporate dynamic context into the policy that governs how, when and why a service mesh should allow or deny traffic. With Styra DAS, any context—including dynamic authentication token data, the type of information being requested, the APIs making the requests, and much more—can be easily incorporated into the policy that governs what can talk to what, all without custom code or app changes.
