When data is spread across many systems, governance fragments: each source has its own permission model, and policies drift. SemanticFed is built to enforce a single policy model at the federation edge.
You define row filters (a salesperson sees only their region), column masking (PII is redacted unless explicitly granted), and access rules in one place. The engine applies them to every query before results are returned — no matter which underlying source the rows came from.
Policy lives with the model, not scattered across a dozen databases, so an access review is one consistent thing to read, and a change applies everywhere at once.
Illustrative pre-launch scenario describing the governance model being built.
Do it yourself
Define a row filter or column mask once as an access policy, attach it to a model or entity, and have it enforced on every federated query.
Open the Policies page to see the access policies on your models and entities.
You should see: The list of access policies loads.
