B2B Authentication Provider Comparison: Features, Pricing & SSO Support (2026)
Security Boulevard, Friday, April 3rd, 2026
Enterprise SaaS buyers now expect SSO and SCIM support by default.
Most enterprise security teams will reject SaaS products that do not support SSO. Identity infrastructure has become a core requirement for B2B SaaS platforms.
Modern authentication providers help SaaS companies integrate:
- Enterprise Single Sign-On (SSO)
- Directory synchronization
- SCIM user provisioning
- Multi-factor authentication
- Passwordless login
Instead of building authentication infrastructure internally, most SaaS companies rely on specialized identity platforms.
