Sometimes new users aren't sure what proXPN is for, or how they can use it. This article will attempt to clear that up for those users.
When you connect to proXPN, you create an encrypted tunnel through which all of your internet traffic (web browsing, email, any internet application) passes. While you are connected to proXPN, no outside party can see what is passing through the tunnel. This protects your privacy. All data goes through the tunnel and cannot be seen by prying eyes.
Another side-effect of using proXPN is that when you are connected, your public facing IP address changes from the one issued by your ISP to a proXPN IP address. This masks your real IP address, keeping your true location private. Also, having an IP address in a certain country can be advantageous if you wish to access content that is blocked to users outside of that country, like BBC content in the UK, for example.
proXPN offers three flavors of VPN for flexibility - OpenVPN, IPsec and PPTP VPN. OpenVPN runs over SSL, the same technology that browsers use to secure connections like at banking sites, for example. This allows the VPN connection to slip through firewalls that are set up to filter access to resources on the public internet (censorship, corporate blocks, etc).
IPSec provides data security at the IP packet level. A packet is a data bundle that is organized for transmission across a network, and it includes a header and payload (the data in the packet). IPSec emerged as a viable network security standard because enterprises wanted to ensure that data could be securely transmitted over the Internet. IPSec is supported in Windows and iOS through the proXPN app or by manual configuration for other platforms.
PPTP VPN is built into most operating systems, including Windows, Mac (all versions), IOS, Android, Windows Mobile. This allows maximum flexibility for users. The one downside to PPTP VPN is that it is easy to block on a router level, due to it being hardwired to run on port 1723 using the GRE (General Routing Encapsulation) protocol.
