In this new landscape, the traditional “perimeter-based” security model is not aging well and binary access tools like VPNs, firewalls, and jump servers are proving to be cumbersome and unscalable. Working environments are no longer governed by fixed perimeters. Users work off their own devices and sensitive company data is stored in third-party cloud services. Companies can no longer rely on binary security models that focus on letting good guys in and keeping bad guys out. For modern enterprises, the challenge is how to give users the access they need while reducing set-up and maintenance costs and without compromising security.
