Aserto is a startup that provides a platform for fine-grained, scalable authorization for applications. It operates in the cloud security market, serving a broad range of clients who need to manage access controls for their applications. The platform is designed to be easy to integrate, with the ability to get started in less than 5 minutes.

Aserto's business model revolves around providing a centralized system for managing resource-level access controls. It allows businesses to enforce permissions in real-time, eliminating standing permissions and ensuring that authorization is based on the most current data. This is achieved by deploying local authorizers to the edge of the client's application and syncing changes to authorization data in real-time.

The platform also offers a control plane that simplifies the understanding of authorization logic and the management of access across applications. It is compatible with existing systems, allowing businesses to add authorization to any application using Aserto's SDKs middleware, or its gRPC / REST APIs.

Aserto's platform is built on the principles of zero trust and least privilege, ensuring that users can only access what they need to at the moment. It also offers compliance without the headache, being cloud-native and open source. It supports custom roles, custom attributes, and integration with enterprise identity providers and directories.

In terms of revenue generation, Aserto likely operates on a subscription-based model, where clients pay a recurring fee for access to the platform and its features.
