OAuth governance & SaaS supply-chain defense
Every "Sign in with Google" or "Sign in with Microsoft" click can grant persistent API access to corporate mailboxes, drives, and directories. Elba inventories OAuth grants across Google Workspace, Microsoft 365, and Dropbox, scores vendor reputation from 0 to 10, alerts on vendor breaches and Critical/High CVEs, and revokes risky tokens.

Supply-chain & OAuth controls
MFA on your identity provider cannot stop an attacker who compromises a third-party OAuth token that already holds read/write access to Gmail, Outlook, Google Drive, or SharePoint.
Discover every third-party OAuth application authorized across Google Workspace, Microsoft 365 (Entra ID), and Dropbox, inspect exact API scopes granted per user, and revoke risky or abandoned tokens in 1 click.
Evaluate unfamiliar SaaS and AI vendors with a 0-10 reputation score, and trigger automated Playbooks whenever a connected SaaS vendor discloses a data breach or Critical/High CVE.
Instead of revoking legitimate workflow integrations blindly, ask the employee who authorized the OAuth app in Slack, Microsoft Teams, Google Chat, or email, and auto-revoke grants left unconfirmed after your grace period.
OAuth governance matrix
Compare how lean teams discover, evaluate, and revoke risky third-party OAuth grants.
| OAuth security capability | Native Google / Entra admin portals | Enterprise SSPM ($50k-$100k+) | Elba OAuth & SaaS Security |
|---|---|---|---|
| Cross-workspace OAuth inventory | Separate consoles for Google Admin, Entra ID, and Dropbox | Unified view gated behind six-figure enterprise contracts | Single OAuth inventory across Google Workspace, Microsoft 365, and Dropbox + browser Shadow IT |
| Scope blast-radius & vendor trust | Lists raw scope URIs without vendor reputation context | Complex risk graphs built for dedicated SOC analysts | Plain-language scope impact + 0-10 vendor reputation scoring out of the box |
| Vendor breach & CVE response | Manual scramble through news feeds to check if staff connected a breached app | Requires external TPRM feed or manual SIEM correlation | Built-in Third-Party SaaS Vendor Breach & Critical/High CVE Playbooks |
| Token cleanup without breaking work | Admin revokes blindly or chases users manually on chat | Creates Jira/ServiceNow tickets for IT to chase | 1-click owner verification via Sam (Slack, Teams, Google Chat, email) + direct token revocation |
| NIS2 & ISO 27001 supply-chain evidence | Manual screenshots of consent screens before each audit | OAuth only; still requires separate DLP and access-review tools | Combines OAuth governance, 46-connector access reviews, Cloud DLP, and Browser AI DLP |
Remediation workflow
Move from initial tenant scan to continuous supply-chain Playbooks with zero endpoint friction.
Authorize Elba’s workspace connectors to pull existing user and admin OAuth grants, scopes, and last-used signals immediately.
Filter grants holding broad mailbox, drive, or directory write permissions paired with low 0-10 vendor reputation scores, and revoke unapproved tokens.
Automatically nudge employees via Sam when new risky OAuth grants appear, and alert your team the moment a connected SaaS vendor suffers a breach or Critical/High CVE.

A closer look
Elba discovers, evaluates, and revokes third-party OAuth grants across Google Workspace, Microsoft 365, and Dropbox, and complements them with Okta SSO directory sync and managed browser Shadow IT discovery across Chrome, Edge, Firefox 128+, and Safari 26+.
Elba tracks disclosed data breaches and Critical or High CVEs affecting third-party SaaS vendors in your application inventory. When an incident matches a connected app, Elba triggers your Playbook so admins and affected users can revoke OAuth tokens and rotate access promptly.
Yes. Elba separates basic identity sign-in scopes (such as openid, email, and profile) from high-impact permissions that read or modify emails, cloud files, calendars, or directory users, combining scope severity with a 0-10 vendor reputation score.
