By WSO2 IAM team
Identity and access management (IAM) is the efficient integration and management of identities, giving users access to the right resources at the right time. Identity is no longer a mere security project for enterprises. In the integration and API domain, as businesses continue to increase the number of internal and third-party APIs, it’s more important than ever that APIs are integrated and governed securely. In the user domain, with increasing user identity spaces, company-wide policies, complex structure hierarchies and roles, regulatory pressures, and customer-facing applications, security becomes a bigger challenge each day for identity architects and administrators.
WSO2 Identity Server aims to address both API and user domains while providing an enhanced user experience as part of WSO2’s open source Integration Agile Platform. It’s a highly extensible IAM product, designed to secure APIs and microservices and enable Customer Identity and Access Management (CIAM).
In addition to user access management, the application, container, microservices, and integration spaces have grown in complexity and become more decentralized. The challenges for identity management to secure these models have also increased. For example:
WSO2 Identity Server, a part of the WSO2 Integration Agile Platform, is an open source IAM solution that facilitates single sign-on (SSO) between applications and federates identities between multiple heterogeneous systems. It’s optimized for securing APIs, microservices, and customer IAM projects.
It offers enterprise-grade capabilities, such as identity federation, SSO, strong and adaptive authentication, account management, and identity provisioning, to help digital-native organizations become integration agile through CIAM and API security.
WSO2 Identity Server is based on open standards and open source principles, enabling freedom from vendor lock-in and velocity to innovation. The product comes with seamless, easy-to-use integration capabilities that help connect applications, user stores, directories, and identity management systems.

Business users typically access multiple heterogeneous applications and identity providers (IdPs) that their systems need to integrate with. WSO2 Identity Server alleviates working with identity silos through the ability to connect Java Database Connectivity (JDBC), lightweight directory access protocol (LDAP), or Active Directory (AD) user stores and enforce role- or attribute-based access control with eXtensible Access Control Markup Language (XACML), since user stores alone cannot enable SSO.
Having to fill a form to sign up as a user or having to sign in multiple times creates an unfavorable user experience. Identity federation allows bring your own identity (BYOID) or social logins to access applications and systems. SSO offers the ability to stay signed in to multiple applications. This also includes rule-based authorization support and Google ReCaptcha support for SSO. WSO2 Identity Server offers these capabilities, as well as single logout (SLO) via Security Assertion Markup Language 2.0 (SAML2), OpenID Connect (OIDC) and WS-federation passive, and federated SSO with external providers. With WSO2 Identity Server, you can also integrate with Azure AD, Microsoft 365, and other MS applications with the use of standards such as OIDC for user provisioning. With Microsoft 365, the product can be used to provide SLO and cloud synchronization.
Authentication is the process of validating a user’s identity before granting access to a resource. Strong authentication involves multi-step and multi-option with local and federated authenticators such as FIDO, IWA, SAML2, OIDC, MePIN, email/SMS OTP, and Duo security.
Adaptive authentication with WSO2 Identity Server enables authenticating a user by considering the context factors, such as user’s risk profile/behavior, identity attributes, environmental attributes, device type, geolocation, machine learning algorithms, and request parameters.
With WSO2 Identity Server, an identity admin is able to use ready-made scripting templates to take complete control of the authentication flow to implement adaptive authentication. This includes enforcing rules, attributing transformations, using provisioning/deprovisioning, communicating with external systems, implementing step-up authentication, and more. Based on a user’s context, the authentication sequence changes, providing better usability.
Biometrics are rising in demand as mobile sims can be cloned. WSO2 Identity Server provides federated authentication with biometrics through Veridium, Aware Inc, and other providers.
Identity bridging facilitates exchanging identity attributes and authentication decisions between heterogeneous identity systems and protocols in a seamless manner. This includes bridging tokens (OIDC, SAML2, and WS-Federation), service provider claims to IdP claims (email addresses, phone numbers, and names), and identity provisioning requests (from SCIM and SOAP to SCIM, Google apps, and Salesforce).
End users can manage their own profiles and set account recovery options in a self-service manner. WSO2 Identity Server supports inbound, outbound, and just-in-time (JIT) user provisioning. These features efficiently, cost-effectively, reliably, and securely help organizations manage user information held on multiple systems and applications.
In terms of managing users and groups, WSO2 Identity Server helps with flexible profile management. This includes the ability to link multiple user accounts belonging to a single user, a self-service user portal for profile management, and password management with Google Recaptcha.
Through account management, WSO2 Identity Server offers support for heterogeneous user stores through a built-in LDAP (powered by ApacheDS), an external LDAP, Microsoft Active Directory, or any JDBC database.
Identity provisioning features can be used to propagate user identities across different software as a service (SaaS) providers. Users and groups can be provisioned to external IdPs using SCIM 2.0, and identities can be created on the fly with JIT provisioning.
This controls access to applications in the login flow, with fine-grained access control policies, and acts as a policy decision point for third-party applications. It also helps with managing user entitlements and role-based access control. In this instance, XACML is used as a basis for fine-grained policy-based access control, user-friendly policy administration (PAP), REST profile support, and easy integration with WSO2 Enterprise Integrator.
Securing APIs that are being exposed using OAuth2 access tokens and associated grant types including access control APIs. OAuth2 being a key standard, WSO2 Identity Server offers OIDC support, introspection and form post response mode. The product also provides user-managed access and delegated access control using OAuth2.
WSO2 Identity Server easily integrates with WSO2 API Manager for OAuth2 Key Management. WSO2 API Manager, a part of the WSO2 Integration Agile Platform, is an open source solution that addresses full API lifecycle management, monetization, and policy enforcement. WSO2's offering made the company the only open source vendor to be named a leader in The Forrester Wave™: API Management Solutions, Q4 2018 report.
As for microservices, WSO2 Identity Server offers microprofile JWT 1.0 support for role-based access control and SAML2, JWT assertion, and NTLM-IWA grant types.
WSO2 Identity Server is optimized for privacy regulations such as GDPR, including implementing the Kantara consent management specification. This offers consent management for any application without being locked into a vendor. User consent includes self sign-up to provide consent and for SSO/federation to provide users with choice and control over sharing their personally identifiable information (PII). The product also offers a self-service portal to enable users to control their personal data, manage consent declarations, or make any other changes.
The privacy toolkit is instrumental in removing references of user identity as and when required or when requested by a user.
The product is equipped with powerful monitoring and analytics tools to keep track of the enterprise IAM system’s health when it is deployed in production. The analytics system is capable of generating and analyzing login attempts made via WSO2 Identity Server. In addition, the analytics system is also capable of generating and analyzing information relating to specific sessions that have taken place via WSO2 Identity Server, helping to monitor and prevent fraudulent activity. It can help with manually terminating user sessions and admin-forced password resets.
Each enterprise faces unique identity-related challenges such as integrating user stores, adhering to compliance requirements that come with privacy standards or implementing an authentication system. Whatever the requirement, WSO2 identity Server offers an extensible architecture, with a user store of 40+ connectors, that gives the ability to write custom extensions that enterprises can own. This extensibility also provides authentication and provisioning connectors. Customers such as Nutanix and West Corporation use WSO2’s product for the extensibility it offers.
Scalability is important to ensure that an IAM product can load balance and accommodate a large number of logins or users. WSO2 Identity Server currently manages 75mn identities and more for enterprises such as Trimble, State of Arizona, Express (retail) and more.
WSO2 Identity Server also provides a wide array of ready-to-use connectors that can be used to connect with cloud and other third-party systems to build tailor-made solutions. This helps to write custom extensions, based on the third-party application enterprises, and enables quicker integrations, with out-of-the-box compatibility with cloud and on-premises applications, third-party authentication systems, and social IdPs.
WSO2 Identity Server is also a part of the WSO2 Integration Platform that includes WSO2 Enterprise Integrator and the WSO2 API Manager. The platform comprises components required for the digital transformation of an enterprise in an API-driven world. Such an example is CIAM, where these components come together to bridge all customer identities and applications to provide an insightful experience.
All these options come with the same seamless developer and IT personnel experience.
