Business travel is integral to the bottom line for most large companies. As a result, the number of business trips taken by U.S. workers alone tops 237 million annually. Travelers typically have a laptop in tow to help them get the job done. That flotilla of computing power may boost productivity, but it also exposes companies to an ocean of risk. Companies need to understand the threats they face and make sure that they have adequately armed their mobile fleet with the technological tools that can protect against these threats.
