Ubisecure B2B Identity Management is an identity and access management platform designed for managing external business relationships including partners, vendors, and supply chain participants. The platform supports both B2B and B2C scenarios and can be deployed as IDaaS, on-premises, or in hybrid configurations. The solution provides multi-tenant architecture with federated access capabilities, allowing organizations to manage complex business-to-business relationships. It incorporates Legal Entity Identifiers (LEI) for verified organization identity, combining organizational verification with individual identity authentication to establish trust in business transactions. The platform includes delegated administration capabilities that enable business partners to manage their own users and access rights within defined parameters. This supports multi-tier hierarchies including organization-to-organization, organization-to-individual, and individual-to-individual relationships. The delegation model includes onward delegation and electronic power of attorney functions. Authentication features include multi-factor authentication with support for TOTP, SMS OTP, passkeys, biometrics, and PKI. The platform connects to external identity providers including verified identities (BankID, NemID, eID) and social identities, supporting bring-your-own-identity (BYOI) scenarios. Step-up authentication allows users to register with low-friction methods and increase authentication strength as needed. The system provides user management across multiple subtenants, centralized authorization services, and API-based integration capabilities. It supports KYC and KYB workflows using verified organization data and includes features for managing agent and broker-based business models in B2B2C scenarios.
