Security remains one of the foremost inhibitors to expanding wireless application use in the enterprise. We expect that within the next 1-2 years, 50-65 percent of companies deploying wireless applications, many of which have been deployed with minimal security built-in, will acquire tools that secure and manage those applications. Moreover, with an increasing array of different device types and platforms in use, companies will concentrate on suites that provide maximum platform support while integrating into the existing non-mobile security capabilities enabled in most organizations. Products like Good Mobile Defense enable badly needed enhanced security in enterprise wireless deployments.
