What is the VPN Client?
The VPN Client is a tool that staff and faculty members can use if they need to access on-campus network resources from off campus. Usually these resources are protected by our network firewall, and therefore are blocked from off-campus usage or the PSU wireless network. Some of these resources include Banner access, remote desktop access, and I drive access for some database applications.
The VPN client software creates a secure 'tunnel' through the internet from your home computer to the PSU network. This added security layer allows you to safely connect to PSU resources as if your home computer were physically on the PSU network.
