Virtual Private Networks (VPNs)
Last updated
What is Virtual Private Networks (VPNs)?
A Virtual Private Network (VPN) creates a secure, encrypted connection over a less secure network, like the internet. It essentially extends a private network across a public one, allowing users to send and receive data as if their devices were directly connected to the private network. This is achieved by routing the user's internet traffic through a VPN server, masking their IP address, and encrypting their data.
