RSA Authentication Manager by RSA Security is an on-premises identity, authentication, and access management solution that balances security and convenient authentication across various use cases. The system acts as a security-hardened authentication server that works with RSA SecurID hardware tokens, software tokens, and biometric authentication methods to validate user identities. It can be deployed via hardware appliance or virtual appliance to enable multi-factor authentication (MFA), access control, and centralized identity management for cloud, hybrid, and on-premises environments, delivering 99.99% availability through failover mechanisms.
