Convergence is the best word to sum up this appliance-based offering. Imprivata OneSign brings together three pieces of identity management. The first is authentication management, which replaces Windows-based authentication with stronger methods that can be managed in one place. Next is single sign-on, which is implemented for all legacy, client/server, Windows, Java and web applications in an easy and efficient manner. The final piece is physical/logical, an interesting feature that can integrate network and building access systems to provide a single consolidated user identity based on specific policies.
