What is a VPN?
VPNs (Virtual Private Networks) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips). Today they are increasingly being used for personal use by individuals to protect their privacy while online in public places (e.g. when using the wi-fi connection in a cafe) or in a country where the internet is censored / blocked (e.g. China, Saudi Arabia).
Why do I need a VPN?
Whether youre an expat living in a foreign country where the internet is heavily regulated, a mobile user constantly on the road, or just someone concerned with maintaining their privacy online, having aVPNis becoming essential.
