Remote access enables users to access files and other system resources on any devices or servers that are connected to the network at any time, increasing employee productivity and enabling them to better collaborate with colleagues around the world. Remote access is usually accomplished with a combination of software, hardware and network connectivity.

One common method of providing remote access is via a remote access VPN connection. A VPN creates a safe and encrypted connection over a less secure network, such as the internet. VPN technology was developed as a way to enable remote users and branch offices to securely log into corporate applications and other resources.
