Virtual Private Network (VPN)

As a business grows, it might expand to multiple offices across the country and around the world. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks. In addition, travelling employees like salespeople need an equally secure and reliable way to connect to their business’s computer network from remote locations.

One popular technology to accomplish these goals is a VPN (virtual private network). A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together.
