Difference Between Virtual Private Network (VPN) and Proxy

Computer NetworkMCAComputer Engineering

In networking both VPN and Proxy used to connects to the remote system where one can access the host system from remote location. On the basis of process of connection to the host system we can differentiate between both Proxy and VPN are as follows.

Following are the important differences between Virtual Private Network (VPN) and Proxy.

Sr. No.KeyVirtual Private Network (VPN)Proxy
1DefinitionVPN is basically a mechanism to simulate a private network over public network which includes implementation of encryption and authentication to connect to the network and access the remote system.On other hand in case of Proxy simulation of private network does not occur and access the remote system is without any encryption and authentication.
2ProtocolsIn case of VPN protocols used such as PTTP (Point to point tunnelling protocol), L2TP (Layer 2 tunnelling protocol) etc.On other hand Proxy uses protocols such as Proxy are FTP (File transfer protocol), SMTP (Simple mail transfer protocol) HTTP (Hyper Text Transfer Protocol) etc.
3FirewallVirtual private network uses firewall for its execution.On other hand proxy do not use firewall for its execution.
4IPIn case of Virtual private network IP address of client is visible and do not get hide over the network.On other hand in case of proxy IP address of client is hidden and get hide over the network and uses the anonymous network ID as IP.
5SecurityVirtual private network provides high security and is more secure as compare to the Proxy.While Proxy does not provide as secure connection as VPN does and hence is less secure as compare to the VPN.
