UNINAC Network Controllers
Introduction Introduction Number of devices growing exponentially Networks are becoming increasingly vulnerable Identifying who and what connects to network becoming important Networks need to be secured internally and externally Today s network tools are not adequate to meet demands Need to Identify Threats, Enforce Policies and Protect networks Network Access Control provides full network visibility and control Helps become proactive rather than reactive 2
