Uncompromised Control: Identity That Runs Your Way

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.

Challenge

If SaaS Controls Your Identity, Who Controls Your Risk?

In highly regulated environments, control is not optional - it's mandated. For enterprises facing national sovereignty requirements, strict regulatory mandates (HIPAA, GDPR, FedRAMP), OEM redistribution, or vendor-neutral strategies, handing identity to a rigid SaaS provider is a non-starter. You're surrendering both where it runs and how it behaves. SaaS vendors increasingly gate enterprise capabilities - SAML, FAPI, advanced federation - behind opaque pricing tiers that punish growth.

Impact of Doing Nothing

When You Don't Control Identity, Risk and Cost Compound

Without centralized control, bespoke authentication stacks drift out of compliance, policies diverge, and audit findings pile up. Your development team is stuck maintaining fragile integrations, outdated security practices, and custom identity code that all compounds with every workaround. All while SaaS callbacks into on-prem systems add latency, risk, and friction that make every cloud or hybrid migration slower and more expensive.

Solution

Your Identity Foundation

Your Rules

Duende IdentityServer gives you a control-centric identity foundation that preserves sovereignty over credentials, tokens, and infrastructure - deployable on-prem, sovereign, or air-gapped. Own where identity runs and how it behaves.

Full Control

Command over UI, UX, business logic, and data. Keep credentials in your directories (AD/LDAP/HR) and run identity entirely inside your infrastructure.

Modular Add-Ons - Extend When You're Ready

Add the capabilities you need as a flat-fee or usage-based add-on. Avoid overpriced SaaS bundling and forced platform upgrades. Introducing: User Management, SAML, Financial-grade Security & Conformance, Automatic Key Management, and Multi-Issuer.

Infinite Hosting Possibilities

Self-managed on containers, Kubernetes, Windows, Linux - even offline or air-gapped. Your architecture dictates deployment, not the vendor.

Standards & Compliance

IdentityServer v8 delivers OAuth 2.1 and FAPI 2.0 compliance improvements, a built-in Conformance Report, production-ready DPoP, and modernized .NET 10 platform types. Provable compliance, not just promised.
