Today, 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 are protected from security threats, and
users outside the traditional network boundary have no acceptable use policy
enforcement, minimal protection against malware, and a high 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).

Traditional network and content security solutions are great for protecting users
and assets behind the network firewall, but are useless when users or devices are
not connected to the network, or when data is not routed through the security
solutions.
