Enterprise organizations can use access policies to define which data each group of users can read or write on a resource. Retool enforces access policies on every query that runs against the resource. A policy can grant access to whole tables, specific columns, or specific rows.
For example, you can use an access policy to restrict an EMEA group's access on a table to only the customer rows for their own region. Retool applies that restriction to every query the group runs against the resource, so it holds regardless of which app, query, or agent the request comes from.
One policy covers queries from apps, the query library, raw SQL, and agents. Workflow queries against an enforced resource are blocked, so account for any workflows using the resource before you turn enforcement on. Retool supports access policies on PostgreSQL resources.
Access policies are enabled by default on cloud instances. On self-hosted instances, navigate to Settings > Beta and toggle on the feature flag for Enforce data security using access policies. To create a policy:
- Open a PostgreSQL resource and select the Access Enforcement tab.
- Turn on Data access enforcement.
- Create a policy, choose the groups and environments it covers, and define its rules.
- Activate the policy, then click Save changes.
Turning on data access enforcement closes the resource by default in every resource environment. Access policies apply only to the resource environments you select, so grant broad access first and narrow it once your policies are in place. Refer to Configure access policies for more details.
Access policies operate by granting access, not denying access. Refer to Access policies and Data access enforcement for more information.
