OAuth scope minimization audits over-permissioned OAuth2 grants by inventorying service principals and delegated permissions via Microsoft Graph. It classifies scopes by risk level to prioritize remediation for third-party and internal applications.

OAuth scope minimization is the process of tightening overly broad scopes and stale grants to reduce data exposure. You need to review third-party app permissions when auditing identity providers to enforce least-privilege access and curb third-party risk.

Generate a remediation plan by inventorying OAuth2 permission grants and classifying them by risk. This identifies unapproved apps, excessive scopes, and stale grants, producing actionable guidance to implement least-privilege access in your production environment.

Yes, you need Microsoft Graph admin credentials and permissions to query Service Principals, OAuth2 permission grants, and sign-in activity. These credentials are required to inventory grants across your organization's identity providers and SaaS platforms.

The best way to prioritize remediation is to classify OAuth scopes by risk level after inventorying all grants. This approach identifies risky consent patterns, stale grants, and overly broad scopes across SaaS platforms to support a targeted remediation plan.

Yes, you can use Python with the requests library to query Microsoft Graph endpoints. The workflow requires admin credentials to inventory OAuth2 permission grants across service principals and generate a prioritized scope reduction plan.
