The Internet facilitates a great deal of business activity around the world by enabling communication and data exchange across network boundaries, effectively creating a global marketplace. However, transmitting sensitive information across the public Internet always carries a risk of exposure, which is why most organizations rely upon virtual private networks (VPNs) to create secure connections.
