Challenge

Regulators Move Faster Than Legacy IdPs Can Adapt

Open banking, PSD2 Strong Customer Authentication, FAPI 2.0, and CFPB Section 1033 keep raising the bar for authorization security. Most vendors ship consent flows that force you to solve each new regulation with a manual plugin and turning their technical debt into your financial burden.

Impact of Doing Nothing

Compliance Debt Compounds. Transactions Don't Wait.

Policy drift surfaces in every SOC 2, ISO 27001, and PCI cycle. Fragmented consent logs turn regulator inquiries into archaeology. Token theft and session hijacking go unaddressed; payment flows and account aggregation stall waiting on a vendor's roadmap. Every workaround compounds.

Solution

Financial-Grade Identity Infrastructure, Expanded on Your Terms

Duende IdentityServer gives .NET teams an identity foundation that’s standards-compliant, fully extensible in C#, and deployable wherever your regulator requires. Add capabilities as your regulatory surface grows through modular add-ons, with one roadmap and support contract, and no third-party bolt-ons.

Financial-Grade Security & Conformance

Validate your existing Duende IdentityServer configuration against FAPI 2.0 and OAuth 2.1 requirements and produce an audit-supporting conformance report with remediation guidance.

Transactional Consent

Rich Authorization Requests carry per-transaction detail into the approval screen and into an access token scoped to that one transaction. Every consent is queryable, every approval auditable.

Decoupled Authentication (CIBA)

Client-Initiated Backchannel Authentication for call-center, voice-banking, and agent-initiated flows, so a human approval can be bound to a specific transaction on a second device

Deploy and Extend Without Vendor Boundaries

Deploy on-premises, private cloud, or air-gapped. Data stays in your jurisdiction, keys in your HSM. When you need custom grant types, claim transformations, or policy decision points, you write them in C# against a first-party extensibility surface.
