VPNs disguise your actual IP address and location. The network service scrambles your data in a process known as encryption. The VPN service puts your internet data into capsule, of sorts, to send it through a private tunnel to the website you requested.For an organization looking to provide a secure network infrastructure for its client base, a VPN offers two main advantages over alternative technologies: cost savings, and network scalability. To the clients accessing these networks, VPNs also bring some benefits of ease of use.
