Microservices broke your authorization model
In a monolith, all your data is in one place, and so is your access control. But with microservices:
Data is scattered across databases and services.
Teams implement access control differently.
You can't filter lists or enforce rules consistently across services.
This leads to drift, duplication, and delay.
Centralize Your Permissions, Plug Into Any Database
Oso supports a hybrid model for authorization data:
- Shared permissions data lives in Oso Cloud.
- Application-specific data stays in your database.
Use Oso’s SDKs to evaluate permissions locally, no need to sync everything.
- List filtering enforces permissions at the database level, returning only the data a user can access.
- Centralized, readable policies ensure consistent authorization logic across all services without duplicating code.
- Operational tooling, including auditing, decision logs, and testing tools to verify policy changes before they reach production.
