FusionAuth is a single-tenant CIAM solution that deploys on-premises, in your private cloud, or on their fully-managed FusionAuth Cloud. Their JSON REST API provides advanced identity management that is easy for developers to deploy and implement on any platform or framework.
“We have complex needs in that we’re a multi-sided, multi-tenant enterprise SaaS platform and need to support customer specific identity providers for SSO. We also require end-to-end authentication across different applications, microservices, and APIs. FusionAuth’s flexible multi-tenant architecture and first-class developer experience enabled us to unify all of this in short order, and made it simpler than others to do so.”
