Aserto helps developers build secure applications. It makes it easy to add resource-level authorization to any application or API. 
 Aserto handles all the heavy lifting required to achieve scalable, real time authorization. It offers ~1ms authorization decisions coupled with a centralized control plane for easy management of policies, user attributes, resource and relationship data, and decision logs. It’s flexible enough to support any authorization model (RBAC, ABAC, PBAC, ReBAC) and easy enough to implement that a single developer can go from prototype to product ready in 1-2 weeks.
