What is a VPN?
VPN stand for Virtual Private Network. It is a group of computers networked together over the internet. 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.
When you connect to a VPN, you launch a VPN client on your computer, log in with your credentials, and your computer exchanges trusted keys with a far away server. Once both computers have verified each other as authentic, all of your internet communication is encrypted and secured from eavesdropping.
The most important thing you need to know about a VPN: It secures your computer’s internet connection to guarantee that all of the data you’re sending and receiving is encrypted and secured from prying eyes.
