This functionality has been greatly enhanced over the 2004 version of the
product as well.

Using the Firewall Client to Control Individual User Access
In addition to the default capability to support traffic from any Internet client
(SecureNAT clients), ISA includes the capability to restrict, control, and log individual user
firewall access through the installation and configuration of ISA firewall clients. Although
it is a less common deployment scenario by virtue of the need to install and support a
client component, using the ISA Firewall Client can create scenarios that are more secure,
and also enable an administrator to control firewall policy based on individual users or
groups of users.
For more information on deployment scenarios involving the ISA Firewall Client, see
Chapter 11, ???Understanding Client Deployment Scenarios with ISA Server 2006.???
Augmenting an Existing Security Environment with
ISA Server 2006
One of the major steps forward for ISA Server was the change in focus from an assumption
of ISA in a Microsoft-only environment to a focus where ISA is an additional layer of security
to existing security technologies.
