Aserto — Developer Tools

What does Aserto do?

Aserto is a fine-grained authorization platform that lets developers add resource-level access controls to any application or API in minutes. It enforces permissions in ~1ms and supports any authorization model (roles, hierarchies, subscriptions, sharing & collaboration) across any cloud.

What problem does it solve?

Traditional authorization (e.g., simple role-based access) is too coarse for modern, zero-trust applications. Aserto replaces standing permissions with real-time, context-aware decisions—using user attributes, organizational relationships, and environmental conditions—so you can enforce least-privilege access without building complex custom infrastructure.

Who is it for?

Aserto is built for developers and SaaS vendors who need scalable, centralized authorization. It’s ideal for teams using Auth0, Okta, Azure AD, or GitHub/GitLab for identity, and who want to avoid rolling their own policy engine.

Real use cases

• Multi-tenant SaaS: Restrict document access per organization, team, or folder.
• Internal tools: Control admin vs. viewer permissions across apps from one dashboard.
• API gateways: Enforce per-endpoint authorization based on user role, department, or time of day.

• ~1ms authorization — Real-time enforcement without caching stale decisions.
• Any model, any cloud — Supports roles, hierarchies, subscriptions, sharing, and policies that reference user attributes and org-chart relationships.
• Get started in <5 minutes — SDKs for Node, Go, Python, Java, .NET, Ruby, plus sample apps and quickstarts.
• Central control plane — Manage users, policies, authorizers, and authorization data from one place.
• Edge authorizers — Deploy local decision engines that sync in real-time for low-latency enforcement.
• Pre-built integrations — Connects to Auth0, Okta, Azure AD, GitHub, GitLab, DockerHub, and SIEM tools like ELK and Splunk.
• Zero trust & least privilege by default — Policies can incorporate environmental attributes (time, location) and dynamic relationships (manager-of, can-read).
