Case Study: Seegno Simplifies Multi-Tenant Authentication with FusionAuth

Seegno Manages Thousands Of Tenants With FusionAuth And Kubernetes

Seegno, a software development team working across industries including financial services, retail, real estate, cybersecurity, and bioinformatics, needed a scalable way to handle authentication for multiple applications and thousands of tenants. Before adopting FusionAuth, they relied on a homegrown auth system and wanted a headless, self-hosted, configurable solution that could support multi-tenancy, token/session management, and social login.

Seegno implemented FusionAuth as a multi-tenant authentication service, using its API and Node client to manage tenants, users, session tokens, JWT encryption keys, email confirmation codes, and passwordless login. Running FusionAuth in Kubernetes, the team now supports over 5,000 tenants in their largest environment and estimates that rebuilding and maintaining these capabilities in-house would have taken hundreds of hours; they also highlighted FusionAuth’s configurability and responsive support as key advantages.
