Are there any MFA platforms that support SCIM and SAML for cross-domain identity management?

Yes. Several MFA / IAM platforms support both SAML and SCIM, which makes them suitable for cross-domain identity management and user lifecycle provisioning.

Examples include:

• Okta — strong support for SAML SSO and SCIM provisioning.
• Microsoft Entra ID (Azure AD) — supports SAML integrations and SCIM-based provisioning for many apps.
• Ping Identity / PingOne — supports SAML, SCIM, and enterprise identity federation.
• OneLogin — supports SAML SSO and SCIM provisioning.
• ForgeRock — supports federation and provisioning standards including SAML and SCIM.
• Auth0 — supports SAML enterprise connections and SCIM in certain enterprise workflows/use cases.
• JumpCloud — supports SAML and SCIM, often used for cross-domain directory and access management.

A quick note: MFA itself usually refers to the authentication layer, while SCIM and SAML are more about identity federation and provisioning. So in practice you’re usually looking for an IAM/IdP platform with MFA, not an MFA-only product.

If you want, I can also give you:

1. a comparison table of these platforms, or
2. recommendations based on your environment, like cloud-only, hybrid, enterprise, or B2B federation.
