ZyWALL USG 1000 is a Unified Security Gateway engineered to provide a variety of security services on top of a robust, hardware-accelerated platform. By integrating both IPSec VPN and SSL VPN technologies, the ZyWALL USG 1000 allows organizations to establish Virtual Private Network (VPN) connections amongst multiple locations such as remote branch offices, business partner sites and even a remote teleworker getting connected in a potentially unsafe hotel hotspot. Communication channels are securely encrypted so that information leakage / data theft can be mitigated when transmitting confidential information over insecure networks, such as the Internet. The Hub and Spoke VPN feature is capable of reducing policy management overhead dramatically in a complex, multi-site corporate network infrastructure.
