Virtual private networks (VPNs) have been a staple of enterprise remote connectivity for more than two decades since they replaced old Frame Relay and dial-up systems. Their ability to provide low-cost and secure connectivity for remote users and networks has been unparalleled. VPNs have played an increasingly critical role in enterprises as workplace patterns have shifted to more remote workers and telecommuters.
