The Enterasys Networks introduces the SecureStack B3 stackable switch for customers looking for industry- leading performance at an economical price point. The SecureStack B3 delivers line rate switching as well as policy capabilities that enable customers to deploy a role-based policy on their network. By offering unprecedented port density in a stackable switch, the SecureStack B3 allows customers to start small and then keep growing. In addition, customers can upgrade their switches to an Enterasys Secure Network via a license upgrade, providing many of the features that make Enterasys Networks known as the Secure Networks company. Enterasys Secure Networks is the role based security architecture where every user is assigned an easy to deploy, yet highly granular role on the network. The SecureStack B3 supports up to 768 policy rules per switch or stack. Once users are authenticated to the network (using 802.1X, MAC, or optional web authentication), they are then controlled according to the rules of their particular role.
