FusionAuth offers Risk-Based Authentication (RBA) that adapts security measures based on a variety of factors including user behavior, device information, IP address, geographical location, and additional contextual indicators. Its flexible architecture, paired with event-driven webhooks, enables you to initiate step-up authentication, restrict access, or identify irregularities in real-time. The platform provides complete customization of authentication processes, allowing developers to craft sophisticated risk models and react promptly to potential threats. When integrated with Multi-Factor Authentication (MFA) and other security measures, RBA significantly improves account security without compromising user experience—making it a suitable choice for organizations adopting zero-trust frameworks or those that are compliance-focused.
