The BiGuard SSL VPN Appliances: BiGuard SSL VPN Gateway VPN Functionality and Introduction

To provide a secure long distance access is a key requirement for those enterprises whose employees need to work from remote places to require the resource of an enterprise. If enterprises want to keep their productivity under the environment of their employees working from remote offices, internet cafes or hotels, then they need a solution to solve the difficulty of acquiring company's resource from remote places. VPN (Virtual Private Network) is a technology built upon the current Internet infrastructure. It creates secure encrypted VPN tunnels between two points. Since VPN is more secure and cost effective than those traditional leased line or private networks, such as ATM, MPLS, or Frame Relay, so VPN is widely accepted and recognized by enterprises.
