How does Auth0 (Okta Customer Identity) differ from Okta Workforce Identity?

Auth0 is optimized for Customer Identity and Access Management (CIAM) — securing customer-facing applications with social login, progressive profiling, customizable login flows, and B2B organization management. Okta Workforce Identity manages employee authentication and authorization for internal applications, SaaS tools, and infrastructure access.

What authentication protocols and standards should enterprise IdPs support?

Enterprise IdPs must support: SAML 2.0 (for legacy enterprise applications), OpenID Connect (OIDC) for modern OAuth 2.0 applications, SCIM 2.0 for automated user provisioning/deprovisioning, LDAP proxy for legacy directory-integrated applications, and WebAuthn/FIDO2 for phishing-resistant passwordless authentication.

How do enterprises implement Zero Trust network access with IdP integration?

Zero Trust access with IdP integration uses: continuous identity verification (not just at login), device posture assessment integration (MDM compliance signals from Intune, Jamf), risk-based adaptive authentication (challenging unusual logins with step-up MFA), and policy enforcement at every access request through integration with ZTNA/SSE platforms (Zscaler, Cloudflare Access, Netskope).
