Virtual private networks (VPNs) are a necessary protection in an inherently insecure internet world. Enterprise-class VPNs have been around forever and there are a multitude of vendors to choose among. Most require a dedicated centralized device (e.g., an appliance, gateway, firewall, concentrator or server) to which all participating VPN users connect.

Now a growing new class of VPN vendors, especially in the small business and mobile space, uses the power of the cloud to scale their decentralized offerings. Some are even completely free.

Traditional VPNs rely on the IP address of the user to remain stable. Mobile VPNs can adapt to changing IP addresses as users move around and connect through, say, a hotel LAN or wifi hotspot. This is because mobile VPNs are bound to logical IP addresses whereas traditional VPNs require a stationary address. The logical IP address is tied to the device.
