For many enterprises, the solution is a centralized single sign-on (SSO) infrastructure that leverages the enterprise directory with federation, multifactor authentication and centralized access control to give users one URL and login to access all their enterprise applications and services–without having to type in another URL or enter credentials a second time. At the same time, it provides IT with a single identity, access control and management infrastructure, closing the inevitable security and management gaps inherent in juggling multiple gateway solutions. Such a solution would offer the best of all worlds, combining enhanced user productivity with IT efficiency, cost effectiveness, security and compliance.
