Setting up a VPN is quite easy, often as simple as entering a username and a sever address. Flagship smartphones can configure VPNs using PPTP and L2TP/IPsec protocols, while all major OS can configure PPTP connections. OpenVPN and L2TP/IPsec protocols need small open source applications, and certificate downloads.

The number of protocols and available security features of VPN are constantly growing. The most common among them are:

PPTP – It has been around since Windows 95, and the main selling point is the fact it can be simply setup on all major OS. PPTP tunnels a point-to-point connection over GRE protocol, but unfortunately, its security is in question in recent years. However, it is still going strong, but it is not the most secure.

L2TP/IPsec – It is more secure than PPTP and offers several more features. This protocol is a way of implementing two protocols together to gain the best of both worlds. For instance, L2TP creates a tunnel and IPsec provides a secure channel, giving you a secure package.

Open VPN – This is an SSL-based VPN is becoming more popular. It uses open source software and it is freely available. SSL is a mature encryption protocol, and OpenVPN runs on a single UDP or TCP port, meaning that it is extremely flexible.
