Technical Depth
Built for engineers
who care about control.
PermStack is designed as an authorization platform, not a security add-on. Every capability is built around clean separation of policy, identity, and resource logic.
RBAC
Define roles with fine-grained permissions. Assign users to roles across resources and tenants with inheritance and overrides.
ABAC
Enforce context-aware access policies using attributes such as department, location, time, or custom metadata fields.
Policy Engine
Write structured access policies in a human-readable format. Evaluate them in real time against incoming requests.
Multi-Tenancy
Full namespace isolation per tenant. Each organization has its own roles, users, and policies with no cross-tenant bleed.
Audit Logs
Immutable event logs for every permission evaluation, role change, and policy update. Export in structured formats for compliance workflows.
Identity Integration
Connect with Okta, Azure AD, Auth0, Google Workspace, and custom identity providers via standard OAuth 2.0 and OIDC flows.
