15 Identity Providers Your B2B Saas Must Support To Close Enterprise Deals
Security Boulevard, Thursday, April 23rd, 2026
B2B SaaS companies must support 15 specific identity providers to close enterprise deals, with Okta, Microsoft Entra ID, Google Workspace, Ping Identity, and OneLogin covering 80% of Fortune 2000 requirements.
This guide ranks 15 identity providers (IdPs) by their frequency in enterprise security questionnaires rather than market share, with Okta, Microsoft Entra ID, Google Workspace, Ping Identity, and OneLogin covering roughly 80% of Fortune 2000 deals.
Supporting SAML 2.0 alone is insufficient; modern enterprise buyers require OIDC and SCIM 2.0 for automated user provisioning, with SCIM support becoming non-optional for deals above $50,000 ARR.
The article explains that enterprise buyers prioritize IdP support for security, compliance, and offboarding speed, as a single missing integration can kill otherwise successful deals.
