Users and their devices are increasingly more mobile, connecting to the Internet
from several locations, such as the office, home, airports, or cafes. Traditionally,
users inside the network were protected from security threats, and users outside
the traditional network boundary had no acceptable use policy enforcement,
minimal protection against malware, and are at a higher risk of data loss.

Employers want to create flexible working environments where employees and
partners can work anywhere on any device, but they also want to protect corporate
interests and assets from Internet-based threats at all times (always-on security).
