What Is a VPN?<\/h2>\r\n

A\u00a0virtual private network<\/strong>\u00a0(VPN<\/strong>) extends a\u00a0private network\u00a0(intranet) across a public network (Internet), and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network while taking advantage of the flexibility of the Internet.<\/p>\r\n\r\n[caption id=\"attachment_7700\" align=\"alignright\" width=\"300\"]\"A Figure 1. Using a VPN is one way a business can protect sensitive information.[\/caption]\r\n\r\n

In a business setting, remote-access VPNs allow employees to access their company's\u00a0intranet\u00a0from home or while traveling outside the office. Site-to-site VPNs allow employees in geographically separated offices to share one cohesive virtual network.<\/p>\r\n

To ensure security, the VPN connection is established using encryption protocols and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN.\u00a0Although VPNs cannot make online connections completely secure, they can increase privacy and security. For example, to prevent disclosure of private information, VPNs typically allow only authenticated remote access using encryption\u00a0techniques.<\/p>\r\n

  • the VPN messaging is designed to detect instances of tampering with transmitted messages<\/li>\r\n<\/ul>\r\n

    As security concerns continue to grow in the digital age, more and more companies are emerging to serve the growing demand for VPN services. Which service a business chooses will be determined by its planned uses for the VPN.<\/p>\r\n
