Keycloak & OIDC Security Audit

Find risky OAuth clients before a leaked secret becomes an incident.

AuthSigma helps platform and security teams identify client-secret exposure paths, stale service accounts, risky client-credentials flows, weak redirect URIs, and overbroad scopes across Keycloak and OIDC environments.

Fixed-scope audit. Practical remediation backlog. Delivered in 5–10 business days.

Your biggest identity risk may not be the login screen.

OAuth and OIDC environments often accumulate hidden risk over time: stale clients, long-lived secrets, service accounts with broad access, weak redirect URI patterns, unclear ownership, and limited visibility into how client credentials are used. If a client secret leaks, most teams cannot quickly answer what it can access, where it is used, or how fast they can contain it.

Stale OAuth Clients

Unused clients accumulate over time. Each one is a potential lateral-movement surface with valid credentials and forgotten access grants.

Over-Permissioned Service Accounts

Client-credentials flows often carry broader scopes than the service requires. Compromised accounts mean over-broad access with no human MFA backstop.

Leaked Client-Secret Exposure Paths

Secrets embedded in JavaScript bundles, CI/CD configs, repositories, or environment files create silent exposure that standard SAST often misses.

Weak Redirect URI & Scope Design

Wildcard or over-permissive redirect URIs enable open-redirect and token-hijacking attacks. Overbroad scopes amplify the blast radius of any compromise.
