 In a scanty local area network LAN with few, very trusted users and good physical security, clear-text data going over network wires is not likely to elevate security-related risk very much. The further this data is transmitted, the greater the risk because there are more distinct points at which clear-text data can be captured without authorization. Sending clear-text data from one point to another over a public network, however, raises security-coordinated concerns to an entirely different level. Virtual Private Network VPNs are secure tunnels over a public network, most notably the Internet. This secure tunnel allows two private, internal networks to spread over the public network without compromising the communications that flow over them. The two networks may be corporate LANs, a single remote machine from the vast pool of road warriors that your company has, or an employee working from home.
From a consumer perspective, each user is on the internal network. Each has access to all the resources available to someone who is physically connected to the regional LAN. The speed or bandwidth is probably the only noticeable difference in a true...

IPSec is often referred to as a "security overlay" because of web use as a security layer for other protocols.

Both protocols use a "handshake" method of authentication that involves a negotiation of network parameters between the client and server machines. Free free web based proxies initiate a connection, an authentication process involving certificates is used. Certificates are cryptographic keys that are stored on both the server and client.
