What is the use of SSL VPN?

SSL VPN (Secure Sockets Layer Virtual Private Network) allows users to remotely access restricted network resources via a secure and authenticated pathway by encrypting all network traffic and giving the appearance that the user is on the local network, regardless of geographic location. This protocol achieves a higher level of compatibility with client platforms and configurations for remote networks and firewalls, providing a more reliable connection. While Northwestern University Information Technology (NUIT) continues to offer its traditional VPN to the University community at large, SSL VPN is the next generation of VPN service.

SSL VPN also allows access to administrative systems, critical infrastructure, and sensitive information maintained by system administrators. SSL VPN access can be granted to University system administrators as well as vendors and other external collaborators, provided that the user has a valid NetID and password and is in an LDAP (Lightweight Directory Access Protocol) group with SSL VPN access.
