We're looking at a number of device control applications and I was
wondering if Zen's Endpoint Security Management(ESM) offers the ability
to disable network bridging?

I.e. We have a number of users that have 3G data cards. We've caught a
few users bypassing out proxy server (web filters) by using there 3G
data cards while connected to the network. Does ESM allow the creation
of policies that either:
1) Disables all other network devices when the Ethernet connection is active
2) Or, allow for the creation of online(connected to the LAN) and
offline(Not connected to the LAN) policies so that different devices can
be enabled or disabled based on policy?

Hope that all makes sense :)

Thanks in advance.
