As a business grows, it might expand to multiple shops or 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. Traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations. Even while on leisure, people want to keep their computers safe when on an unfamiliar or unsecured network.
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. The VPN uses "virtual" connections routed through the internet from the business's private network or a third-party VPN service to the remote site or person. VPNs help ensure security — anyone intercepting the encrypted data can't read it.
