Identity as a Service (IDaaS)

Identity as a Service, or IDaaS, is a cloud-based service that provides functionality for managing digital identities. With IDaaS, organizations can control access to applications and data by leveraging cloud-delivered authentication, authorization, and identity management capabilities. This approach replaces or supplements traditional on-premises identity solutions such as Active Directory.

At the heart of IDaaS is the concept of centralized identity management combined with the flexibility and scalability of the cloud. Users can log in to various applications via Single Sign-On (SSO), reset passwords, manage permissions, or enable multi-factor authentication—all through a unified platform.

IDaaS offers numerous benefits, especially for companies with hybrid or fully cloud-based IT infrastructures: it reduces complexity, enhances security through consistent access controls, and simplifies user lifecycle management—from onboarding to role changes to offboarding.

The main challenges lie in integrating existing systems and selecting the right provider, as not all IDaaS solutions offer the same range of features or level of customization. Additionally, data privacy and sovereignty are key concerns, since sensitive identity information is handled by external providers.

When implemented properly, IDaaS enables modern, scalable, and user-friendly identity and access management—a core element of any zero-trust strategy and a key enabler of secure digital transformation.
