The future lies in having one identity for each user, which works across multiple systems and multiple domains, making the user experience seamless. Those systems could be placed on corporate intranets, enterprise extranets, or on the open internet. Along with that single identity comes the need to have granular access controls for each user, as all users have different needs when accessing systems.
Without Federated Identities, enterprises need to work out costly synchronization techniques or manually manage each single identity at each domain.
Enterprises have a lot to gain from Identity Federation in several different ways:
- Reduced administration for and stronger relationships with customers by offering seamless access to corporate resources. The automation also removes any disruption in productivity when users cannot use services due to account locking, password resets, etc.
- Reduced administration for internal users using external services
- Enablement of Single Sign-On to internal applications that reduces costs and improves end user satisfaction.
- Increased security and control over both internal and external users.
- Ideal for online business partnerships and company/departmental mergers.
