eTrust Single Sign On offers SSO functionality across a broad spectrum, from client applications to web applications, secured databases and virtually any networked application. It also offers useful tools to administer users, policies and even sessions.
Aladdin's eToken SSO solution is based on the use of USB tokens upon which information is stored, including user data, application profiles and, if you wish, other certificates. This makes for a particularly intuitive operation as, once everything is set up, you just plug in your token and enter your password once. And when you have finished, simply remove the token.
GemSafe Logon is intended for the individual computer. It is self-contained, but with an administrative twist. Access policies are set up centrally by an administrator who creates a configuration file for the individual smartcards and distributes it to users. This is practical for smaller installations but perhaps not for large, distributed enterprises.
The Authenex ASAS system is a very robust system designed for large companies. It requires a standalone server running Windows 2000 with SP4 or Windows 2003. It must also have a Radius or SQL server on the system to allow for use of the integrated database of A-Key tokens supplied with the system.
ActivCard AAA Server has been designed for industrial or large-scale implementation. Its separate administrative console allows for delegation of multiple administrator roles if the situation calls for it. Installation of the software only requires a system large enough to hold Windows Server 2003 running as a Domain Controller.
