Similarly, VPNs securely connect geographically disparate offices of an organization, creating one cohesive network. VPNs allow employees to securely access their company’s intranet while traveling outside the office. Businesses use VPNs to connect remote datacenters, and individuals can use VPNs to get access to network resources when they’re not physically on the same LAN (local area network), or as a method for securing and encrypting their communications when they’re using an untrusted public network. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.Ī Virtual Private Network, or VPN, allows a group of computers or networks to connect to each other over public network-usually, the internet. There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. VPN is a network that is constructed by using public wires - usually the Internet - to connect to a private network, such as a company’s internal network.
