Point-to-Point Tunneling Protocol VPN (PPTP VPN) – This is a software-based VPN system that uses an existing internet connection. In this scenario a secure “tunnel” is created between two points, allowing a remote user to connect to a remote network by using an existing internet connection. Windows Server has a built-in PPTP that you connect to via a native VPN client within Windows. PPTP establishes the tunnel but does not provide encryption. Nevertheless, it is used in conjunction with the Microsoft Point-to-Point Encryption (MPPE) protocol to create a secure VPN. When using this method your company will have lower overhead cost, making it more cost effective for Small and Medium Business because the software is built into most Microsoft operating systems. Pro and Cons: In the past PPTP has been criticized for its various security flaws, but in the current versions of the protocol many of these issues have been addressed by using Continue reading The Ends And Outs of VPN
