How To Set Up A VPN With Linux: A Comprehensive Beginner’s Guide

A VPN or a Virtual Private Network basically means creating a secure private network using public infrastructure. This process helps create a protected network that can help employees of the same company but based in different parts of the world work together in a setting that provides the utmost privacy and confidentiality. It can also be used by home users who value privacy and don’t want prying eyes to glance at everything that they do and see.

The encryption that is present in a VPN helps the two or more interacting parties keep their shared information secret and does not let others get an idea of the things that are being discussed. This is how an encrypted connection between two or more computers that are present in far-off locations can go a long way in giving complete freedom to people who are interested in safeguarding their web history from anybody who wishes to monitor the same.
