Split tunneling is a process used to allow a remote VPN user to access the internet and the resources on the VPN simultaneously. Split tunneling helps the user to access remote devices while accessing the public network. It is useful in avoiding bottlenecks and safeguard bandwidth. This is possible because the internet does not have to go through the VPN server when split tunneling is used.
Split tunneling is used because of the many benefits it offers. It transmits data that requires VPN protection which results in smaller workloads for VPN clients, gateways and server. It keeps private internet use and professional internet traffic separated. The biggest advantage is that it conserves bandwidth usage as it need not transmit private data. Many erroneously believe it is a security risk but experts this method can be made foolproof by using security patches and upgrading technology which will ensure high security of data and information.
