CyberArk serves a broad range of industries and offers tiered pricing, so it's a good option for those that want to move to a Zero Trust model.

Another strong contender is RSA, which offers a unified identity platform with advanced authentication, anomaly detection and machine learning-based risk assessment. It includes single sign-on, self-service and unified directory features, so it's a good fit for the most secure environments. RSA offers a variety of customizable products and professional services to help customers get the most out of their identity security investments.

Clerk is also a good choice, particularly if you need a full-stack user management platform that includes multifactor authentication. Clerk offers advanced security features like session management, bot detection and secure password authentication, and offers flexible APIs and admin dashboards. It integrates with popular frameworks and tools, so it's a good fit for different authentication needs.
