See every OAuth app authorized in your org and cut the ones you can't justify before one goes rogue

Video thumbnail

Quick Summary: OAuth apps accumulate authorized access silently - approved once, never reviewed, often long after the original use case ended. Oleria, an AI-native identity security & governance platform, surfaces every OAuth app in your org with the scope it holds so you can cut the ones you can't justify before one becomes a breach vector.

Outcome

Cross-tenant OAuth apps. End-user-consented integrations. Dormant grants from a vendor pilot two years ago. Mail.Read scope on apps nobody can name. This is exactly how Midnight Blizzard reached a production tenant - and how the next breach will start at your org if you can't answer the question today.

The reality

OAuth grants are the modern attack surface. They don't show up in MFA reports. They don't expire on their own. They survive the user who consented and the project that needed them. A forgotten test-tenant OAuth app holding Mail.Read across an entire org was the entry point in a major breach last year. A ransom campaign in 2024 exploited malicious OAuth apps in GitHub. A credential-chain attack against a major cloud platform pivoted through third-party OAuth grants into customer tenants. Each one started with an OAuth grant nobody was watching.

The numbers are bigger than people realize. Enterprise orgs commonly carry 200 to 2,000+ OAuth apps. 15 to 30% hold scopes the security team would consider sensitive (Mail.Read, Files.Read.All, Directory-level). More than half were granted via end-user consent rather than admin consent in many environments - meaning a single user click added a third party to your trust boundary.

What makes this stubborn: native admin consoles list OAuth apps but stop at the IdP boundary. Entra shows you Entra apps. Okta shows you Okta apps. Salesforce shows you Salesforce connected apps. Cross-tenant grants, apps from unverified publishers, and apps holding refresh tokens to long-lived sessions all hide in different places. Stitching them together is something the operator has to do manually - and rarely does. The pattern only shows up when you can ask one question across every IdP and SaaS platform at once.

What you get with Oleria

Oleria delivers comprehensive OAuth App Authorization Audit and Governance across every IdP and SaaS platform from Entra and Okta to Salesforce and GitHub in a single, continuously updated view.

One cross-IdP OAuth inventory the individual consoles can't give you.

OAuth apps from Entra, Okta, Google Workspace, GitHub, Slack, Salesforce - in the same table. No more stitching together separate admin consoles that don't talk to each other.

Scope sensitivity flagged automatically so you don't miss the dangerous ones.

Mail.Read, Files.Read.All, Directory.Read.All - flagged against vendor and OWASP guidance. Customizable per IdP for your environment.

End-user consent separated from admin consent - because that's where supply-chain risk accumulates.

Most platforms don't make this distinction. Oleria does, and routes end-user-consented sensitive-scope apps directly to a review queue.

Publisher risk signals surfaced so you can act before the incident.

Apps from unverified publishers, new publishers, or publishers that recently changed - each routed to the right reviewer automatically.

How it works

  1. Connect - Read-only OAuth to each IdP and SaaS platform that issues OAuth apps.
  2. Ask - Filter by scope, consenter, last-used, scope-versus-used delta.
  3. Review - Triage by sensitive-scope count, by unverified publisher, or by unused-but-still-authorized.
  4. Act - Revoke, narrow scope, request a review, or hand to a security-review workflow.

What it looks like in your environment

You connect Entra, Okta, Google Workspace, GitHub, Slack, Salesforce. Within an hour, the OAuth inventory is 1,847 apps. Of those, 212 hold sensitive scopes. 89 are end-user-consented. 47 haven't authenticated in the last 90 days. You hand the dormant-grant queue to a remediation workflow. Mean time from new OAuth grant to security awareness goes from 90 days to same-day.

What good looks like

  • OAuth app inventory coverage: IdP-by-IdP silos → one unified view across all platforms. From "we have OAuth apps somewhere" to 1,847 apps prioritized and queryable.
  • Sensitive-scope apps reviewed: ad hoc → periodic cadence with named reviewer. Not "we should do that someday."
  • End-user consent: ungoverned → admin-reviewed within a defined SLA. Admin consent only, or admin review of end-user consents within X days.
  • Dormant sensitive-scope apps: invisible → auto-flagged at 90 days. The pattern that enables credential-chain breaches caught before it's exploited.
  • Mean time from new OAuth grant to security awareness: 90 days → same day.

Audit every OAuth app your org has ever authorized — before an attacker does.

Sensitive scopes, forgotten grants, and end-user-consented integrations are all live attack surface. Oleria surfaces them in under an hour so you can revoke or govern with confidence.

Frequently Asked Questions

Why is this different from our IdP's OAuth admin console?

The IdP console shows OAuth apps for that IdP only. Modern attacks pivot across IdPs - an OAuth grant in one directory, then a connected app in a CRM, then an installation in a code platform, all leveraging the same compromised refresh path. A single view across every IdP and SaaS platform that issues OAuth grants is what the attacker already has. You should have it too.

How do you decide which scopes are sensitive?

Defaults follow vendor and OWASP guidance - Mail.Read, Files.Read.All, Directory.Read.All on Microsoft Graph; equivalents on Google, Salesforce, GitHub. You customize per IdP for your org. The defaults are not opinions, they're what attackers go after.

Do you cover OAuth apps in SaaS apps too, or just IdPs?

Both. OAuth grants in Slack, Salesforce, GitHub, Atlassian, Google Workspace, and other SaaS platforms appear in the same inventory as IdP OAuth apps. The ones in SaaS are often the most ungoverned because nobody thinks of them as identity infrastructure.

Can you detect OAuth apps that are using more scope than they actually need?

Yes. Oleria compares granted scopes against scopes actually exercised in recent activity. An app with Mail.Read.All in its grant that has never touched mail shows up as a scope-versus-used mismatch. That delta is one of the highest-signal indicators of unnecessary privilege in an OAuth estate - and it's something no individual IdP console surfaces natively.

How long does it take to get the first OAuth inventory?

Under one hour from connection. You authenticate Oleria to each IdP and SaaS platform via read-only OAuth, and the inventory populates within the same session. Most customers see their first filtered query results - sensitive scopes sorted by last-used date - before the end of the onboarding call.
