Okta and FusionAuth are two popular identity and access management platforms that cater to different needs of businesses. Okta is a massive organization with complex cloud-based solutions, suitable for large, slow-moving companies with legacy infrastructure. It offers secure access for web and mobile applications through OAuth tokens and API key management. In contrast, FusionAuth provides a streamlined platform designed for scalability without added overhead, ideal for smaller organizations or those with unique security requirements. Both platforms offer full-featured identity tools, including multi-factor authentication, single sign-on, customizable communication templates, and localization support. However, Okta is a multi-tenant "built-in the cloud" service, while FusionAuth offers a single-tenant solution with true data isolation, eliminating data leakage between unrelated companies and providing easier compliance with regulatory restrictions in various industries. Additionally, FusionAuth provides configurable password encryption, brute-force protection, user reports, and analytics, as well as enterprise identity unification and custom feature development capabilities.
