+# Netwrix Activity Monitor v8.0 Documentation
+
+The Netwrix Activity Monitor deploys agents to target environments to provide real-time monitoring
+of activity. It can be configured to provide the event data to other Netwrix products for reporting
+and alerting purposes. The Activity Monitor also provides operational efficiencies and visibility
+into a wide spectrum of human and machine data interactions with a standardized format that is used
+to gain deeper visibility into activity associated with the access, use, and modification of data.
