As business ecosystems grow increasingly interconnected, the ability to securely manage external identities such as partners, contractors, suppliers, and customers has elevated B2B CIAM to a strategic imperative. This session will review the findings from the latest KuppingerCole Leadership Compass on B2B CIAM, with a particular focus on how leading solutions address the complex technical and organizational demands of inter-organizational identity management.
We will begin by outlining the defining characteristics of B2B CIAM, distinguishing it from both B2E and B2C scenarios. The discussion will emphasize capabilities essential to B2B identity use cases, including delegated administration across business units and partner organizations, fine-grained and dynamic authorization models such as attribute-based access control (ABAC), and flexible identity federation to support hybrid trust environments.
The session will then turn to integration requirements that distinguish B2B CIAM deployments, particularly the need to align identity management with line-of-business (LOB) applications and HR or contractor management systems. We will examine how CIAM platforms enable these integrations to support pre-access identity vetting, background checks, and compliance workflows, as well as runtime access governance across multi-tenant environments.
A core segment will be dedicated to the Leadership Compass results, highlighting vendors that demonstrate strength in delegated user lifecycle management, cross-domain provisioning, policy-driven access enforcement, and API-level extensibility for embedding identity services into complex application environments. We will discuss how innovation leaders are approaching B2B CIAM as an orchestration and trust framework rather than simply a scaled-up version of B2C identity services.
Participants will gain insight into architectural and functional trends shaping the B2B CIAM landscape, criteria for vendor evaluation, and how organizations can leverage these platforms to support scalable, secure, and compliant inter-organizational identity ecosystems.

B2B identity ecosystems are becoming increasingly complex across partners, suppliers, franchises, and multi-tenant environments. Traditional TPAG approaches are struggling to scale with modern digital business requirements.
In this session, Devesh explores how organizations are evolving from static third-party access governance toward dynamic, trust-based B2B identity models using automation, group management, policy-based authorization, and identity orchestration to improve both security and business agility.

Partner Identity and Access Management, aka B2B IAM, remains one of the most overlooked areas in digital ecosystems. In the hands of the right, commercially minded digital team, it can be truly transformative.
In this conversation, Olaf Grewe (National Australia Bank), Jerome Tosterson (Salling Group), and Marco Venuti (Thales) challenge assumptions and share lessons from three complementary perspectives: financial institutions, retail supplier ecosystems, and identity solution providers.
The session explores common blind spots in IAM design, including how scale and partner diversity are often underestimated; the role of organizational validation, third-party authentication trust; and how flexible delegation and authorization models can evolve from static to runtime and even event-driven contexts.
Expect sharp insights, cultural humor, and pragmatic takeaways that show how “improper” problem-solving, blending creativity, precision, and a touch of Danish clutter, can lead to more resilient and scalable approaches to B2B identity.
