Obviously VPN is more secure which proof we can get very easily from numbers of corporation who are using VPN since long time. If it is not secure then using of VPN was totally impossible for them.

So for online secure traffic VPN become an essential part for todayís online world which works like a perfect Proxy for us for data transaction.
Setting Up a VPN
Setting up a VPN is very easy task like entering your name and address. We can easily setup VPN by using PPTP, L2TP/IPsec, SSL and OpenVPN to our computer. Almost every operating system is supported to PPTP VPN system. But small application is needed for L2TP/IPsec and OpenVPN.
We should seriously consider about choosing most popular protocol for your VPN because this protocol has also strengths and weakness.
PPTP (Point to Point Tunneling protocol) is really best for beginner VPN user because itís easily configured with any OS (Operating System) like Windows, Mac and also Mobile OS. Unfortunately its security recent come on question as a result itís not secure but still strong.
L2TP (Layer 2 Tunneling Protocol) and IPsec (Internet Protocol Security) are more secure than PPTP with lots of feature and also supported world wide but its setup is little complicate. Here L2TP create tunnel and IPsec supply secure channel which two combinations provide best feature for secure data. It also works given PPTP connection.
SSL (Secure Sockets Layer) provides trusted VPN technology like banking website where you login without any tension. Its deal with web browser also secure like PPTP and L2TP/IPsec.
OpenVPN is SSL based which popularity is being increased day by day. Here open source software is used which is also available online for free. This system is used for creating point to point secure connection like bridge for remote access.
There are lots of VPN provider is seen online on VPN choosing time. From them some charge and rest of other freely provides their VPN service. For financial security issue paid VPN is better than free VPN and we got cheap VyprVPN as reliable with strong security which is providing PPTP, 128-bit encryption, unlimited data usage with download speed and also 5 GB dump truck online storage. So if you want to use VPN just for hiding yourself then free VPN is better but if your purpose of using VPN is financial or strong security related then my recommendation for you please use paid VPN.
