Organizations are quickly realizing that access to applications must be controlled not just for the vast number of vulnerabilities they introduce to the network, but also for the excessive mis-use of bandwidth they consume and the considerable loss of productivity. With employees indulging in non-business application usage with gaming, audio-video downloads through peer-to-peer networks like Kazaa, and more, business critical applications are forced to deal with insufficient bandwidth, resulting in poor Application QoS and frustrated users. The solution is to identify and control access to specific applications so as to achieve optimal bandwidth utilization for business-critical applications.
