Virtual Private Networks (VPN) use encryption and tunneling to extend your company’s private network across a public network, like the Internet.  By utilizing the right VPN solution, your business can operate between regional offices and remote/roaming users as if directly connected to your private network.  VPNs scale quickly from 64k to 100G and can combine with your voice network to reduce costs and decrease the number of circuits you need to manage.  VPN solutions are often cheaper than MPLS and are an excellent choice for data recovery because they can quickly reroute traffic to secure data recovery sites during emergencies..
