What is Identity as a Service (IDaaS)?

Identity as a Service (IDaaS), also known as identity and access management (IAM) as a service, is a cloud-based authentication solution managed by third-party providers. IDaaS firms offer cloud-based authentication or identity management services to enterprises on a subscription basis.

The concept of 'Anything-as-a-Service' (XaaS) in IT refers to delivering functionalities, such as identity management, through third-party providers via the cloud rather than deploying them on-site. For instance, Identity-as-a-Service (IDaaS) manages authentication and access control remotely, much like how Gmail provides email services over the cloud.

The primary objective of an identity service is to authenticate users—confirming they are who they claim to be—and to appropriately regulate their access to software applications, files, and other resources. Managing these services on-site can be difficult, particularly as new challenges arise, such as adapting identity provisioning systems to accommodate employees using a variety of devices under Bring Your Own Device (BYOD) policies. Conversely, IDaaS offers a streamlined, centralized cloud-based system developed by identity management experts. These specialists have extensive experience resolving common and complex identity issues across numerous organizations, making IDaaS a robust and efficient identity-as-a-service solution for modern enterprises seeking reliable access management without the complexity of in-house systems.

Key Features of IDaaS

Identity as a Service (IDaaS) provides a robust framework for managing identities and access in the digital age. Here are some key features that make IDaaS an important solution for modern enterprises:

Single Sign-On (SSO): SSO simplifies the user experience by allowing individuals to access multiple applications and services with a single set of credentials. By minimizing the number of times users need to log in, the SSO solution enhances productivity and reduces the chances of password fatigue.
Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring users to provide two or more verification factors to gain access to resources, making unauthorized access significantly harder. With over 15+ MFA methods available, organizations can tailor authentication processes to suit diverse user needs and scenarios, ensuring robust protection for sensitive data in various environments, particularly those involving Identity as a Service (IDaaS) providers.
Access Management: Efficiently controls who can access what within an organization. IDaaS solutions provide dynamic access controls, adjusting permissions based on real-time assessments of risk and behavior patterns, which is essential for identity and access management as a service.
Directory Integration: Seamlessly integrates with existing directory services, Directory as a Service (DaaS) to manage user identities across various platforms. This integration ensures that all users' identity and access rights are centrally managed, simplifying administration and enhancing security.
User Authentication: A core component of IDaaS, user authentication verifies the identity of users attempting to access systems. This feature is integral to maintaining security protocols and ensuring that access is granted only to legitimate users.
Provisioning: Provisioning refers to the process of creating, managing, and deactivating user access to system resources automatically. Provisioning in IDaaS helps in efficient resource management, ensuring that the rights and privileges are aligned with the organizational policies and changes in employment status.

How IDaaS Works

Identity as a Service (IDaaS) integrates advanced cloud-based technologies into existing IT ecosystems to manage user identities and access permissions efficiently. Here’s a detailed explanation of the architecture, workflow, and integration process of IDaaS:

Architecture and Workflow:

Subscription and Access: Upon subscribing to an IDaaS solution, an organization is provided with an API (Application Programming Interface) and/or a centralized configuration portal. These tools are essential for setting up and managing the integration.
Integration: Organizations utilize the API or configuration portal to connect their application suite with the identity management services offered by the IDaaS provider. This integration is crucial for enabling features such as Single Sign-On (SSO), social login, and adaptive authentication.
Authentication Request: When a user attempts to access an application, the system sends an authentication request to the IDaaS provider via the API. This includes verifying the user’s credentials and asserting their identity.
Identity Verification: The IDaaS system processes this request by checking the user’s identity against secure, cloud-hosted databases.
Access Grant: Once the user is authenticated, the IDaaS system authorizes and grants access to the requested resources, ensuring secure and seamless entry.
Authorization (Optional): Beyond authentication, the IDaaS may perform authorization checks using predefined policies to determine the resources a user is permitted to access.

Integration with Existing IT Ecosystems

Seamless Integration: IDaaS is designed to seamlessly integrate with an organization’s existing IT infrastructure without significant disruptions. This integration involves linking the IDaaS solution with various business applications, directory services, and security protocols already in place.
Compatibility and Customization: The flexibility of IDaaS allows it to be customized to fit the specific needs of an organization, whether it involves complex enterprise systems or simpler web-based applications. This customization capacity makes it a versatile choice for businesses of all sizes.
Centralized Management: By centralizing identity management, IDaaS reduces the complexity and administrative overhead associated with the internal management of user accesses and identities. It provides a unified view and control panel that helps IT teams manage settings, policies, and access controls more efficiently.

Benefits of Using IDaaS

Identity as a Service (IDaaS) provides significant advantages for businesses aiming to enhance their operational efficiency, security, and compliance with regulatory requirements. Here are the primary benefits of adopting an IDaaS solution:
