“Single sign-on (SSO) is an authentication scheme that allows a user to log in with a single ID to any of several related, yet independent, software systems.
True single sign-on allows the user to log in once and access services without re-entering authentication factors.” ~ Wikipedia
Introduction
Single Sign-On (SSO) solutions have become a mainstay in modern digital infrastructure, providing an enhanced user experience and improved security for both users and administrators. Among the numerous SSO solutions available, Keycloak, an open-source identity, and access management tool, has earned a prominent place due to its versatility and cost-effectiveness. Keycloak facilitates authentication and authorization management, offering a comprehensive and customizable suite of features to handle various security requirements.
Cost Savings with Keycloak
One of the main benefits of Keycloak lies in its cost-effectiveness. Being an open-source solution, it eliminates the need for costly licenses or subscriptions typically associated with proprietary SSO solutions. This reduces direct costs and provides an opportunity for indirect cost savings. It does so by minimizing the potential for vendor lock-in, allowing businesses to maintain control over their SSO solution without fear of sudden pricing changes or unexpected discontinuation of service.
Moreover, Keycloak’s extensive feature set and compatibility with numerous standards, like OpenID Connect, SAML 2.0, and OAuth 2.0, reduce the need for additional software or middleware. This further trims down software procurement, installation, and maintenance costs.
Flexibility and Adaptability
Keycloak’s platform-agnostic design makes it an ideal choice for various deployment scenarios. Whether running on dedicated servers, on-premise, or in the cloud, Keycloak can seamlessly integrate with your existing infrastructure. This flexibility makes it a cost-effective option as it reduces the need for significant infrastructure overhauls or supplementary solutions to accommodate different environments.
For businesses operating on dedicated servers or on-premise, Keycloak offers the benefit of enhanced control over data and processes. Running Keycloak on your hardware can be more secure and reliable, given that you have direct control over the servers and their maintenance.
However, if your business is leveraging the cloud’s scalability and accessibility, Keycloak also shines. It can easily be deployed in cloud environments and can take advantage of cloud-based features like auto-scaling and load balancing, ensuring optimal performance even under heavy loads.
Transitioning and Hybrid Scenarios
What if your organization is transitioning from the cloud or vice versa? Or are you considering a hybrid approach, utilizing both on-premise and cloud infrastructure? In these cases, Keycloak still stands out as a robust and adaptable solution.
During transitions, Keycloak can be a steady, unchanging component amidst a shifting infrastructure, maintaining user authentication and authorization without interruption. Its platform-agnostic nature allows it to adapt to new environments without significantly changing its configuration or operation.
Keycloak can bridge the gap between on-premise and cloud infrastructure in hybrid scenarios. Centralizing authentication and authorization ensures a consistent security posture across your entire digital landscape. Regardless of where your applications and data reside, Keycloak can manage access effectively and securely.
Backed by Red Hat of IBM
A major advantage of Keycloak is that it’s backed by Red Hat, a subsidiary of IBM. This brings a level of trust and assurance that is often necessary for organizations of all sizes when selecting critical infrastructure software.
This backing ensures that Keycloak is a reliable solution for small to medium-sized businesses. Red Hat has a long-standing reputation for providing robust open-source solutions, and its support for Keycloak testifies to its quality and durability. Small to medium-sized companies can use Keycloak knowing that it’s a secure and reliable tool that is being continually developed and improved.
For larger corporations, this backing is even more significant. Large corporations often have stringent requirements for their software solutions. The software must be reliable, secure, and capable of scaling to meet their needs. Moreover, it needs to be supported by a reputable company that can provide assistance when necessary. Red Hat’s backing fulfills all these requirements, making Keycloak an ideal choice for large corporations.
Furthermore, Red Hat’s backing offers the benefit of a broad and active community of developers and users. This community continually contributes to Keycloak’s development, providing regular updates, patches, and new features. This ensures that Keycloak remains at the forefront of SSO technology, adapting to new security challenges and integrating new technologies as they emerge.
Extensibility and Manageability
Another noteworthy feature of Keycloak is its ease of extensibility and manageability. Keycloak has been designed with customization and extensibility at its core, making it a versatile solution for various unique business needs.
Keycloak provides a comprehensive administration console, which makes managing its configurations straightforward. The console is user-friendly and intuitive, enabling administrators to manage realms, clients, roles, and users without needing to understand complex command-line interfaces or programming languages. This significantly simplifies managing and adjusting Keycloak’s settings to meet an organization’s specific requirements.
In addition to its manageability, Keycloak is also highly extensible. It provides a well-documented, plugin-based architecture that allows developers to extend its capabilities by creating custom providers for user federation, authentication, and social login, among others. This means that if your business has specific needs not covered by Keycloak’s extensive out-of-the-box features, you can create custom plugins to address these needs.
Keycloak’s support for scripting further enhances this extensibility. You can write scripts in JavaScript, which can be used in various parts of Keycloak, like authentication flows or protocol mappers, to add even more flexibility and customizability.
Moreover, Keycloak’s extensibility continues beyond its own boundaries. It provides comprehensive APIs, which allow you to integrate it with other systems and applications in your infrastructure. Whether it’s synchronizing user data with your CRM, linking it with your email system for user notifications, or integrating it with your monitoring systems for security audits, Keycloak’s APIs can handle it.
User-Friendly Interface
Keycloak’s benefits are not just limited to its backend functionalities; its front-end design also merits attention. Keycloak’s user interface (UI) has been designed with simplicity and ease of use in mind, both for administrators managing the system and for end-users interacting with it.
For administrators, Keycloak’s comprehensive and intuitive admin console significantly simplifies the process of managing the system. The console allows administrators to easily handle various tasks such as user management, session management, and configuring identity providers. The console is organized into logical sections, and complex configurations can be handled through easy-to-understand forms and settings. Moreover, it provides a visual way to manage complex flows, such as authentication or identity brokering, making it easier for administrators to understand and customize these processes.
For end-users, Keycloak provides a clean and straightforward interface for login, account management, and consent. It comes with a default theme that is modern and user-friendly, but it also allows for full customization. You can create custom themes to match your company’s branding, ensuring a consistent user experience across all your applications. The user-facing pages are responsive and designed to work well on various devices, including desktops, tablets, and mobile phones.
Furthermore, Keycloak’s UI supports internationalization (i18n) out of the box. It can display its default messages in various languages, and you can easily add support for more languages or customize the existing messages. This makes Keycloak a user-friendly choice for businesses with an international user base.
