Discover shadow IT and risky OAuth grants across every unmanaged application before one becomes a breach

Security and IT teams gain complete visibility into the shadow IT and unmanaged application landscape — every third-party application that has been granted access to corporate identity and data through OAuth, every employee who has authorized it, every scope that grant enables, and the risk it represents. Risky OAuth grants, over-scoped application permissions, grants held by privileged accounts, and grants that persist after employee offboarding are surfaced as prioritized posture findings and driven to revocation through structured campaigns.

This use case transforms shadow IT from an unquantified risk into a governed, continuously monitored part of the identity security program — making every OAuth grant as visible and accountable as any formally provisioned application integration.

Why shadow IT is an identity security problem:  Every time an employee clicks "Authorize" on a third-party application using their corporate identity, they create an OAuth grant — a standing permission that gives that application access to their email, calendar, files, contacts, or other corporate data, for as long as the grant persists. Most organizations have hundreds or thousands of these grants across their workforce, the majority of which were never reviewed by IT, carry scopes far broader than the application needs, and remain active long after the employee stops using the application — or after the employee leaves the organization entirely.

Shadow IT exists precisely because it bypasses formal IT processes. The tools and processes designed to govern application access — IDP-managed provisioning, application catalogs, change management — were never designed to capture the OAuth grant landscape. Without a purpose-built platform, organizations face:

·  OAuth grants are invisible to IDP-centric access governance.  An OAuth grant is issued by an employee authorizing a third-party application directly — it does not go through the IT provisioning workflow, it is not recorded in the application catalog, and it is not visible in IDP admin consoles that focus on formally provisioned SSO integrations. The grant exists in the IDP's OAuth consent store, but this data is almost never surfaced in any access governance tool.

·   The scope of exposure is systematically underestimated.  A single OAuth grant may authorize a third-party application to read all email, access all calendar events, read and write all files, or manage contacts — using only the permissions the employee's own account holds. An employee with privileged access who authorizes a shadow IT application with broad scopes has effectively granted that application privileged access to corporate data. This compound risk is invisible without a platform that joins OAuth grant scope data with the granting identity's access profile.

·  Grants persist indefinitely after use ends.  OAuth grants do not expire automatically in most platforms. An application authorized once by an employee three years ago may still hold an active grant — with valid access to that employee's email and files — even if the employee has not opened the application since. The grant persists until explicitly revoked, which almost never happens without a systematic discovery and remediation process.

· Offboarding does not revoke OAuth grants on local accounts.  When an employee is offboarded and their IDP account is deactivated, OAuth grants they made using local SaaS credentials — rather than IDP-federated accounts — may remain active. The third-party application retains a valid token that can continue to access data even after the employee's corporate account is disabled. This is the same offboarding gap that affects all local accounts, amplified by the potentially broad scope of the OAuth grant.

· No inventory of which applications have been granted access to corporate data.  Without a platform that specifically ingests and analyzes OAuth consent data, organizations have no reliable inventory of which third-party applications hold active access to corporate identity and data. The shadow IT application population is unknown in size, unknown in scope, and unknown in risk — until a breach makes it visible.

·  Privileged accounts granting OAuth access create compound risk.  An executive or administrator who authorizes a third-party productivity application with broad email and file scopes has granted that application access to potentially sensitive corporate communications, financial data, and confidential documents. Without visibility into which privileged accounts have active OAuth grants and what scopes those grants enable, this compound risk is systematically undetected.

Oleria Trustfusion ingests OAuth grant data from connected identity providers and SaaS platforms, maps every grant to the identity that issued it, evaluates the risk of the grant based on scope, granting identity privilege, and grant age — and surfaces the shadow IT application landscape as a continuously maintained, risk-prioritized posture view.
