Easily add resource-level permissions to any SaaS. Multi-tenant applications need more than roles in isolated environments. They need fine-grained permissions.

Go beyond roles

Justified access, not just access. Marry user information from your identity providers and directories with dynamic context data from your application, to ensure that only the right users can access the right resources.

Identity & context-aware access

Authorize in a millisecond, based on fresh data. Enjoy the blazing fast authorization of a local microservice, with the scalability of a distributed system.

Fast & scalable authorization

Evolve authorization as requirements change. Aserto natively supports RBAC, ABAC, PBAC, ReBAC, and combinations. Start with the simplest model and seamlessly evolve to more powerful ones when the time is right.

Seamlessly evolve your model

Add authorization to your app in minutes, not months. Go, Node, Java, Python, Ruby, and ASP.NET SDKs & quickstarts are available, as well as GraphQL, gRPC, and REST APIs.  

Easy implementation

Your users want to share resources they own with others - let them. Add resource-level secure sharing to your app in minutes.

Allow your enterprise customers to mix and match your permissions into their own custom roles.

Add trials, feature bundles, add-ons, and custom pricing packages to your app. Customize  frontend experiences with external policies, rather than feature flags or updates to code.

Automatically capture every access decision made, along with all of the inputs. Easily export these audit trails to your SIEM tools, or share them with auditors as proof of compliance.

Self-serve custom roles 

Full audit trails. Automatically capture detailed logs for every decision made, along with all the inputs and reasoning. These audit trails can be used for anomaly detection and proof of compliance.

Simplify compliance and audits 

Turn access on or off. Support internal teams; provide a support agent with access to customer records once assigned to that customer, and revoke it when that is no longer the case.

Mix and match features and support custom product packaging. Restrict the features and capabilities that are available to your end-users without deploying the app.

Decouple authorization logic from code, so that it can evolve without redeploying the application. Externalized policies can also be treated like code, version controlled, tested, and signed.

Zero trust and least privilege by nature. Aserto helps you implement best in class security standards with a fine-grained, real-time access control system that defaults to deny.
