Future-Proof Compliance and Financial-Grade Security
Adopt evolving security standards while gaining uncompromised control over policy, consent, and audit evidence - all from the secure, .NET-native core.
Challenge
Modern Standards Outpace Legacy IdPs
In highly regulated industries, compliance now moves faster than legacy identity systems can adapt. Auditors expect FAPI 2.0, dPoP, mTLS, PAR, JARM, and auditable consent as baseline. Yet most IdPs can't deliver, forcing costly workarounds and leaving policy, logging, and claims control outside your reach. Your developer team is caught in the middle, trading speed for compliance or compliance for speed.
Impact
Every Audit Cycle,
the Gaps Get Wider
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.

Solution
Spec-Compliant Identity with Deep Control
Duende IdentityServer is a spec-compliant identity core that sits between apps and IdPs - centralizing policy, consent, and logs at a single, extensible Authorization Server. Built by industry leaders and pioneers in security standards, including OpenID, OAuth, BFF, and FAPI, Duende IdentityServer helps you meet evolving standards and protect critical transactions - without re-platforming or losing control.
Standards Adoption:
Built-in support for FAPI 2.0, mTLS, PAR, JARM-aware flows and verifiable tokens. Adopt financial-grade and government standards without app rewrites.
Central Policy Engine:
One place for MFA rules, scopes/claims, session lifetimes, step-up triggers. Deep Extensibility to plug in custom risk analysis.
Audit-Grade Evidence:
Complete, queryable logs for consent, authz decisions, and high-assurance events. Make audits and incident response faster.
Risk-Based Auth at the Authorization Server:
Decisions externalized from the app and signaled via ACR/AMR and claims. Unifies controls and apps don't need rewrites.
