Styra, the team behind "Cloud Native Authorization" recently announced a few feature called "Styra Run". Their launch blog back in July described Run as being "a new holistic approach" to authorization. But that is trying to solve? Styra are behind the popular Open Policy Agent - a policy driven decision engine for authorization in cloud native environments. Whilst likely OPA is focused on the protection of infrastructure (think containerized ecosytems) it is also used for protecting APIs and custom applications. The developer-first angle sees a dedicated rule language and the storage of policy data in files. The OPA project on github has over 7000 stars.
