Introducing the next era of Duende IdentityServer.
Meet evolving security standards while maintaining uncompromised control over policy, consent, and audit evidence — all from a secure, .NET-native identity foundation.
In highly regulated industries, compliance moves faster than legacy identity systems can adapt. Auditors expect FAPI 2.0, DPoP, mTLS, PAR, and auditable consent as baseline. Yet most identity providers can't deliver. Your development team is caught between speed and compliance.
Doing nothing only magnifies the problem. Policy drift and inconsistent controls lead to recurring SOC 2, ISO, HIPAA, and PCI findings, while fragmented evidence slows audits and incident response. Static MFA frustrates users and ignores risk context, and each new standard demands costly, time-consuming app rewrites. Compliance debt compounds, turning operational drag into real business risk.

Standard-compliant by design, Duende is your extensible identity infrastructure for centralizing policy, consent, and audit logging across every application in your architecture. Built by pioneers in OpenID Connect, OAuth, BFF, and FAPI, Duende gives your team full control over identity and access while keeping pace with evolving security standards and protecting critical transactions.
Financial-grade security built in, not bolted on. FAPI 2.0, DPoP, mTLS, and PAR are native to the framework - your team adopts evolving standards through configuration, not costly application rewrites.
Centralize MFA rules, session lifetimes, scopes, claims, and step-up triggers at a single Authorization Server. Extend with custom risk logic through deep extensibility hooks — without scattering policy across applications.
Complete, queryable logs for consent decisions, authorization events, and high-assurance transactions. Give auditors the evidence they need and your team the visibility to respond to incidents - fast.
Define authentication and risk controls once at the Authorization Server. Every connected app inherits them automatically - improve both security posture and user experience without per-app rewrites.
