The small and medium enterprises (SMEs) category was won by iWebGate from Perth, Australia, and will receive a $300,000 research and development contract. Their product “DMZ in a Box” delivers a low-cost virtual, highly secure reception area between organizations’ trusted networks and the public Internet providing the first line in a layered cyber-defense-in-depth.
