Corporate networks are encountering the highest levels of change in history. Users require anywhere, anytime access to the network from a variety of company- and personally-owned mobile devices. In addition, applications have evolved to be highly dynamic and multifaceted, blurring the line between legitimate business applications and those that waste time and increase the company's exposure to internet-based threats. As a result, organizations must take a new approach to security - without abandoning time-tested methods - to unify the network's security framework, accelerate business innovation, and proactively protect against new and emerging threats.
