Monitoring mode
is designed for evaluating
Deep Edge on a production network without
blocking any traffic or making
Deep Edge a point of failure in the
network flow. In monitoring mode,
Deep Edge is invisible to the
network. Establish the correct monitoring settings on the network switch to mirror
traffic to the
port that connects to
Deep Edge.
Deep Edge will apply policies to the mirrored traffic, but only logs violation-related information.
Network traffic is never blocked by policies in this mode.

Deep Edge in Monitoring mode
In monitoring mode, network traffic does not pass directly through Deep Edge. Deep Edge runs independently
outside the network (logically) aided by the switches of the network which mirror
the specified
traffic to interface(s) on which Deep Edge listens. Deep Edge monitors the status of the traffic and presents the
information to the Deep Edge user.
Trend Micro suggests Deep Edge be
deployed at the core Internet switch in order to see a copy of all Internet traffic
leaving and
entering the network. Deep Edge requires at least two network
interfaces to function correctly in Monitoring mode. In addition to the interface
that Deep Edge uses to listen for traffic, there should be another connection
for Deep Edge to access the Internet to connect to the ActiveUpdate
and WRS query servers, as well as other cloud protection sources that Deep Edge offers.
Monitoring mode is typically used when:
- The network already has related devices (firewall, IDPS) deployed, but there is a
lack of
visibility into the overall network posture. In this case, Deep Edge
provides visibility without dramatically changing the network topology.
- Before deploying Deep Edge inline,
Monitoring mode could help with the evaluation of the Deep Edge device. After learning the security benefits provided by Deep Edge, you could change from Monitoring
mode to either Bridge mode or Router mode for true inline protection.
