A vir­tu­al private net­work (VPN) is a private and secure envir­on­ment with­in the inter­net itself which allows you to send and receive mes­sages and data while main­tain­ing the pri­vacy and secrecy of a private net­work.

That means you could use one to cre­ate a secure tun­nel into your com­pany net­work to enjoy access to private intern­al sys­tems, but also means you could browse com­pletely anonym­ously online and access con­tent you might oth­er­wise not be able to get to such as Net­flix Brazil.

All the traffic that passes through your VPN con­nec­tion is secure and can­not be inter­cep­ted by any­one else mak­ing it the safest way to browse.
