Introducing the next era of Duende IdentityServer.

Secure it, build it, ship it. Govern AI agent workflows with standards-based identity infrastructure. Accelerate identity development with AI-powered Duende expertise. Two sides of the same foundation - securing MCP and building with it.

Centralize authentication and token security across fragmented legacy estates. Deliver secure SSO with velocity while eliminating technical debt and custom code using a modern, .NET-native identity infrastructure - all without application rewrites.

Meet evolving security standards while maintaining uncompromised control over policy, consent, and audit evidence — all from a secure, .NET-native identity foundation.

Run identity anywhere - on-prem, sovereign, or air-gapped - and define exactly how it behaves. Duende IdentityServer gives you complete control over credentials, tokens, flows, and business logic. The standards stay the same and everything else is yours to shape. Use modular add-ons to extend capabilities exactly when you're ready.

Broker and orchestrate federated SSO and complex authentication flows across diverse IdPs (SaaS, on-prem, partner tenants) with the deep control and .NET-native performance your architecture demands.

Bundle a complete, standards-compliant identity engine into your product and ship it under your own brand. Your customers get authentication, SSO, and token security out of the box with no separate setup, no visible third-party dependency.
