These services function very much like business VPNs but go through a VPN provider to reach the internet, rather than via a private business. Individuals interested in securing their communications over unsecured public WiFi networks and remaining anonymous during their online transactions have begun subscribing to paid VPN services. However, these days, VPNs can do much more and they're not just for businesses anymore. By adding a VPN, a business can extend all its intranet's resources to employees working from remote offices or their homes. Intranets enabled distant colleagues to work together through technologies such as desktop sharing. Businesses started by establishing intranets, private internal networks designed for use only by company employees. To take advantage of this, most businesses have replaced leased lines with new technologies that use internet connections without sacrificing performance and security. Today, the internet is more accessible than ever before, and internet service providers (ISPs) continue to develop faster and more reliable services at lower costs than leased lines. Though leased lines are reliable and secure, the leases are expensive, with costs rising as the distance between offices increases. These connections form a single wide-area network (WAN) for the business. Leased lines provide a company with a way to expand its private network beyond its immediate geographic area. Leased lines, such as ISDN (integrated services digital network, 128 Kbps), are private network connections that a telecommunications company can lease to its customers. Several years ago, the most common way to connect computers between multiple offices was by using a leased line. VPNs help ensure security - anyone intercepting the encrypted data can't read it. 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. A VPN is a private network that uses a public network (usually the internet) to connect remote sites or users together. One popular technology to accomplish these goals is a VPN ( virtual private network). Even while on leisure, people want to keep their computers safe when on an unfamiliar or unsecured network. Traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks.
