What is Identity As a Service (IDaaS)?
Enterprises are embracing cloud and mobile technologies. As they do, they’re moving beyond traditional network boundaries and the capabilities of their legacy identity and access management (IAM) solutions.
Identity as a service (IDaaS) is a SaaS-based IAM offering that allows organizations to use single sign-on (SSO using SAML or OIDC), authentication and access controls to provide secure access to their growing number of software and SaaS applications.
Gartner defines IDaaS as, “a predominantly cloud-based service in a multi-tenant or dedicated and hosted delivery model that brokers core identity governance and administration (IGA), access and intelligence functions to target systems on customers' premises and in the cloud.”
Gartner states that the core aspects of IDaaS are:
IDaaS for the digital enterprise
API-first IDaaS for Development Teams
Another way enterprises can leverage IDaaS is through API-first developer platforms. Often used for customer identity and access management (CIAM), these platforms expose all IDaaS capabilities through APIs. This approach allows enterprises to give their development teams a common IDaaS platform that makes it easy for them to embed identity services into their applications. It’s also important to ensure these platforms can meet broader enterprise requirements across all of their applications with:
A focus on security and reliability.
Support for common identity standards (OAuth, OpenID Connect, SAML).
Integrations that allow for coexistence with their on-premises identity infrastructure.
The ability to model their existing identity architecture in the IDaaS platform.
