AuthSec vs WorkOS

WorkOS is the most mature SAML/SCIM enterprise-SSO platform on this list, and it shipped a real Cross-App Access (ID-JAG) implementation in 2026. AuthSec adds certificate-based SPIFFE/SPIRE workload identity, a production Connector Broker, and a self-hostable, open-source deployment model that WorkOS doesn't offer.

Quick take

Where each platform is genuinely strong, before the feature-by-feature detail.

AuthSec

SPIFFE/SPIRE certificate-based workload identity — WorkOS has no X.509/SVID model at all

Connector Broker is a shipped, generalized tool-call proxy; WorkOS's closest product (Pipes MCP) is narrow and early

Open source under Apache 2.0 and self-hostable — WorkOS is cloud-only, with no true on-prem tier

M2M supports both client_secret_basic and private_key_jwt; WorkOS documents client_credentials only

WorkOS

SAML/OIDC breadth: works with effectively any IdP plus a self-serve Test IdP and Admin Portal for customer-side setup

Directory Sync covers dozens of native (non-SCIM) providers beyond AD/Entra, including HRIS systems

Fine-Grained Authorization (FGA) adds a ReBAC-style policy engine layered on RBAC — AuthSec doesn't have this yet

Cross-App Access is a genuinely current, production implementation of the same ID-JAG draft AuthSec's XAA is built on
