Real-time authorization

Eliminate standing permissions. Enforce in milliseconds, based on real-time data.

Deploy local authorizers to the edge of your application and let Aserto do the rest. The Aserto control plane will sync changes to authorization data with them in real-time to ensure you never authorize over stale data.

Central control

Manage all of your users, policies, authorizers, and authorization data from one place.

The Aserto control plane makes understanding authorization logic and managing access across applications as easy as pie.

Aserto centralized authorization system

Works with what you have

Seamlessly add authorization to any application using our complete set of SDKs middleware, or using our gRPC / REST APIs. Then connect your identity provider, user directory, and SIEM tools using our pre-build integration.

Aserto works with what you have

Zero trust and least privilege by default

There is no zero trust without fine-grained access controls. Ensure users can only access what they need to at the moment, and easily change that logic, or what they can access.

allowed { input.user.properties.dept == "Sales" }
Use any user-centric attributes in your policies

Compliance without the headache

Aserto automatically collects and aggregates authorization decisions along with all of the inputs, so you have complete audit trails. You can even map decisions to policy versions and the data that was used.

Share fine-grained decision logs with your logging system

Cloud-native and open source

Aserto is based on a modern, cloud-native, open-source foundation, including the Topaz open-source authorizer, Open Policy Agent decision engine, and a Google Zanzibar inspired directory.

Don't build undifferentiated plumbing

Reinventing the wheel

Authorization is complex

Evaluating policy against real-time user attributes with millisecond latency and 100% availability is a distributed systems problem. Most engineering teams can’t justify taking the time to fully solve it.

Requirements constantly evolve

Custom roles. Custom attributes. Integration with enterprise identity providers and directories. Decision logs. ISO 27001. As products move up-market, teams that build them can't keep up.

You could be building customer value

"I want to rewrite RBAC!" said no engineer, ever. Your team could be working on end-user features instead of undifferentiated heavy lifting.

Built by developers, for developers

David Kerber

VP of Technology

"Authorization involves really hard problems that I want experts to solve. We like to focus our internal engineering efforts on our customers and their problems. Aserto allows us to do just that, at a small fraction of the cost it would take to build and maintain it ourselves, not to mention the opportunity cost."

Mathias Biilmann Christensen

Co-founder & CEO, Netlify

"As millions of developers and businesses are adopting a Jamstack approach, most modern web applications involve multiple APIs and services. Aserto's promise of separating policies from code could radically simplify the implementation of authorization across the front-end UI and the larger world of back-end functions and endpoints."

Tom Preston-Werner

Co-founder, GitHub

"Building & managing an authorization/RBAC system is a huge pain, especially at enterprise scale. So stop! Aserto has a distributed, millisecond latency, 100% availability API for that. I'm excited to help as an angel investor!"
